Prepare for System Design Interview in with Resources Disclosure This post includes affiliate links I may receive compensation if you purchase products or services from the different links provided in this article image credit System Design by Educative ioHello guys if you are looking for new Software developer job in then you should learn System Design concepts and Solve as many System Design problem as possible to excel but System Design is quite vast and you need little bit more than that to succeed The Software Engineering job market is very competitive Especially if you have a couple of years of experience under your belt And in the world of Software Engineering if you are applying for a Senior Engineer Lead Architect or a more senior role System Design is the most sought after skill and hence one of the most important rounds in the whole process If you mess this up nothing else would matter If you get it right though you re looking at a raise of at least tens of thousands of dollars annually So how do you ace your system design round Well here s what I did while preparing for my interviews with Facebook Google and Amazon and it worked out rather well I did end up creating a checklist for myself which got me through most of my rounds so if you follow a similar path you should be able to come up with something that works for you as well Before we get into the details though what is a system design interview What do the interviewers really expect from the candidates Expectations You should be able to design a system that satisfies the requirements given to you and scales well Your design should be pluggable and not restrict the addition of new features You should be able to compare various alternatives and choose the most optimal one Things like which database is the most important or which protocol should you use or what s the best approach to scale a system etc You should know the basics that are relevant from a system design standpoint like Load balancersAPIsCachesDatabasesNetwork ProtocolsMessage queuesCDNsHigh level details about ML and Big dataCAP TheoremMonitoring and analyticsIn the past I have shared the best system design courses and best software design questions and in this article I will share the step by step process to crack System design interviews like concepts common questions and resources to master system design concepts like this list of essential System Design algorithms form ByteByteGo a great platform to learn System Design by Alex xu author of System Design Interview An insider s guide one of the best book for System design Steps to Prepare for System Design Interviews in Here s how you can crack the System design round interview of any FAANG company Facebook META Amazon Apple NetFlix and Google or get into FAANGThere is a simple four step process to ace any System Design round Concepts Learn from the tech giantsFAQsPractice Learn Essential System Design ConceptsAny system design interview will definitely require you to come up with a basic high level design for whatever system you are trying to build There are some components that will be needed for sure Make a note of these components Here are a few Load Balancer  You cannot have a distributed system without a load balancer to distribute the incoming requests among various nodes This ensures proper resource utilization and that there is no single point of failure in your system Here s how Nginx does it CacheMost systems have some read heavy interactions some information that the user will access frequently but not update as much It makes sense to cache this information in such a way that it can be easily fetched without the need for a DB lookup Think low latency Also based on your use case you might need to store more frequently accessed information or more recently accessed information So read up on various eviction policies Here is a nice diagram of how Caching is used in App from ByteByteGo DatabaseAgain there can be no system without some form of data storage Whether you want to store files images product information financial transactions or simply dump all the data from various user interactions to run analytics later It all needs databases So read up on it Find out what matters when you are selecting a database read about SQL NoSQL query patterns and how CAP theorem might come into play while making tradeoffs Message queuesSometimes our system needs to perform some tasks that need to be done but not necessarily immediately or their outcome does not affect the user s journey In such cases rather than making a service call and waiting for the response it makes sense to just write the message to the queue so that it can be executed later What if you need to insert information in your database and bulk insert could be more efficient It would make sense to just keep track of these inserts in a message queue and perform bulk insert instead of hundreds of to inserts to optimize your resources CDNWhen your users are distributed geographically getting your content to them in a reasonable amount of time becomes a real challenge CDNs allow us to maintain a copy of our data in various data centers located closer to the users location to reduce the latency Here is a short video about how Akamai does it Analytics and MonitoringThis is something that is needed in every system you create This is a hidden requirement no one calls it out in the requirement gathering but every interviewer wants this User logs in or logs out Wishlisted an item Payment failed It is all the information for us Anything of importance happens fire an event and save it in your messaging queue You can perform real time analytics on data or just dump it in a Hadoop cluster to use later Similarly if an API call is regularly failing or if your servers are about to run out of resources wouldn t you like to know of it beforehand Network ProtocolsBased on your requirement based on the type of content you are sharing you might need to make a decision on which network protocol to use Read up on various network protocols and when are they relevant what might be the compromises you might need to make etc The first step is to know about all these concepts And by knowing concepts I don t mean just some theoretical knowledge of what these are but more practical hands on experience about what should be used when You need to know things like Which is the best alternative to choose from given the use case What are the tradeoffs that you need to consider while making these decisions Best practices for certain use cases To know most of these things I ll recommend going through this course on System Design by CodeKarle which covers all of the above with concrete examples from the real world Learn from the tech giants read their engineering blog This is probably one of the most underrated tip you will receive and not going to help in the short term But in the long term to become an expert in System Design it s best to look at the Tech blogs of various tech companies and see how they are solving various technical problems This would paint a clear picture of the real problems that they face and how innovatively they solve them  Understanding these things would help you become better at system design and also keep you up to date with the latest innovations in tech Some of the best blogs to follow are Facebook engineering blogNetflix tech blogUber engineering blogYou can also follow blogs of popular tech companies on Medium that s one of the main reason many people take Medium membership Along with that you can also join System Design newsletter run by Alex xu available on ByteByteGo to learn System Design bit by bit Solve Popular System Design ProblemsAn obvious way to get started with your interview prep Knowing the basics is definitely important but it won t be enough The most basic way to get started with your practice is to look at some frequently asked questions and their solutions Most system design interviews revolve around some commonly asked System design questions and if you know the solutions to those you are more than likely to clear this interview The most common System Design questions are Tinyurl System Design Problem with SolutionWhatsApp System Design Problem with SolutionInstagram System Design Problem with SolutionYouTube System Design Problem with SolutionAirbnb System DesignUber System Design Problem How to design Amazon Prime VideoHow to design Google SearchHow to design NetFlixHow to Design a distributed Message QueueDesign a Library Management SystemDesign a Parking Lot SystemIf you need resources to solve these questions something which not only solves the question but also explains the underlying concepts and approach to solving system design questions then this highly rated course by CodeKarle where he discusses most of these case studies and some more problems which has helped many people crack their interviews for companies like Google Facebook Microsoft Amazon etc You can also see the links where you can find tutorials and YouTube video which solves these problems Grokking Modern System Design for Software Engineers amp Managers on Educative course on Educative is another place where you can find the solution of most of these problems Practice Practice and more PracticePractice practice practice Did I say practice There are a lot of resources out there I have shared a few that discuss some of the most popular system design problems in detail Once you go through a few of them you will start noticing a pattern and will soon be able to come up with solutions on your own Get a better understanding of how your systems are designed in your organization How are the other teams doing things What factors do they take into consideration The next best thing is to practice with a friend Make sure you go through a few mock interviews before your actual interview to avoid some common but easily avoidable pitfalls Some most common mistakes that I have seen people make are Not driving the interviewNot asking questionsNot structuring the interview properlyRunning out of timeNot considering the requirementsNot exploring all the alternate design optionsAll these mistakes can be easily avoided by having a few mock interviews with someone who knows System Design well And time your interviews The target must be to reach a solution within minutes including time for some discussion And here is a nice System Design Interview cheat sheet by Educative which you can print and put in your desk for quick revision of essential System design concepts and algorithms That s all about how to prepare for System Design Interviews in I have shared essential

海外TECH	Engadget	The best portable Bluetooth speakers for 2023	https://www.engadget.com/best-portable-bluetooth-speakers-133004551.html?src=rss	The best portable Bluetooth speakers for If there s one thing I ve learned about today s Bluetooth speakers it s that for general consumers the options are pretty good However that doesn t make the process of sifting through the dozens of choices any easier So I set out to test out some of the most popular models in different price ranges Most of the speakers I tried sounded good on first listen it was only through side by side comparisons that I began to suss out the nuances Just reading the spec sheets only goes so far As such we re focusing a bit more on audio quality and dynamic range while also taking into consideration other factors like utility and price Ultimately there isn t one best portable Bluetooth speaker out there but we ve found plenty of good options that will fit a range of use cases and price points What to considerWeather proofingIP ratings Ingress Protection are the alphanumeric indicators you often see in a product s spec sheet that define the tested resistance of a product to both solid objects dirt dust fingers and water It s usually a combo of two numbers with the first indicating solid object ingress and the second being water The former goes from no protection to dust tight The waterproof rating goes from no protection to protected against immersion and high pressure jets When an X is used instead of a number that means the product wasn t tested for resistance If it s waterproof it may have some innate resistance to solids but there s no guarantee IP is a common rating these days indicating highly resistant and potentially rugged speakers These are safe for quick dunks in the pool or tub and should be more than OK in the rain or in the shower They re also good options for the beach playground and other rough environs Additionally speakers with ports and a high rating will often include a tight fitting cover over the charging or auxiliary ports If you plan on using the ports that may limit the product s rated ability to fend off the elements Consider the IP rating and also how you plan to use your Bluetooth speaker when making your decision It may be worth splurging on a better sounding model with a lower IP rating if you ll mostly be using it indoors for instance Battery lifeThe focus of this guide is on portable Bluetooth speakers and while “portable can be a relative term these devices are generally for people who are likely to find themselves far from a power outlet These days around hours of runtime seems to be the baseline but obviously the more battery life you can get out of a speaker the better That said be careful when looking at battery specs as they frequently list a maximum runtime “up to x amount of hours This usually means they tested at a low to mid volume If you like your tunes loud it can often end up cutting the expected usage time in half or more Luckily some manufacturers also list the expected battery life when used at full volume and that transparency is appreciated Additionally if your Bluetooth speaker also happens to have WiFi connectivity they re usually designed for always on functionality Unlike normal Bluetooth speakers that go to sleep after a short period without use these will usually stay awake to listen for your commands and slowly run down the battery If you re out and about you ll want to remember to turn these speakers off manually when not in use to maximize battery life RangeBluetooth range is tricky business Some companies list their product s longest possible range usually outdoors and in an unobstructed line of sight test environment Other companies stick with a foot range on the spec sheet and leave it at that even though they may be running Bluetooth x or x That s likely underselling the speaker s potential but unpredictable environments can affect range and there s little point in promising the moon only to get complaints I ve seen signal drop issues when crouching down with my phone in the front pocket of my jeans and barely feet away from a speaker inside my apartment I ran into this issue across several devices regardless of their listed Bluetooth connectivity range If you re hosting a patio party and duck inside it s wise to have the source device remain close by just in case It s hard to gauge what aspects of any environment may interfere with a Bluetooth signal In general take range specs around feet or more as a perfect world scenario LatencyThis is a minor mention for those out there who use a speaker for their computer output or as a mini soundbar solution for setups like a monitor and streaming box It s annoying to find that your speaker s latency isn t low enough to avoid lip sync issues Luckily it seems that most speakers these days don t often have these problems Only a handful of the few dozen speakers I tried had persistent noticeable lip sync issues Aside from occasional blips all of our picks worked well in this regard If you plan to frequently use a speaker for video playback look for devices with the most recent Bluetooth versions x or x and lower latency codecs like aptX Also make sure the speaker is close to the source device as distance can be a factor To avoid the issue altogether though consider getting one with a wired auxiliary input Price to Tribit StormBox Micro Bluetooth Battery life Up to hoursIP Rating IPAux inputs N AFrequency range Hz kHzApp NoIf you re just looking for an ultra portable speaker that can kick out some decent volume the Tribit StormBox Micro fits the bill The audio quality here is fine it doesn t stand out in terms of fidelity but the volume you get from this affordable little speaker is what makes it a good choice If you re bopping about outdoors on your bike or chilling in the park it s usually more about portability and volume anyway The rubbery rear strap works well on relatively thin things like belts backpacks and bike handlebars While it s small and affordable the speaker doubles as a USB C powerbank to charge your devices in a pinch and you can wirelessly connect two of them for party mode or stereo sound It also supports voice assistants for both iOS and Android users UE Wonderboom Bluetooth N ABattery life Up to hoursIP Rating IPAux inputs N AFrequency range Hz kHzApp NoThe UE Wonderboom is a tiny yet powerful portable delivering the biggest sound in its size range that we tested It s still a cute barrel shaped speaker with a nubby little strap that probably needs a carabiner to help attach it to most things But this refreshed model includes a couple of bright new colors an extra hour of battery life and improved wireless range With an IP rating on top of the company s five foot drop test durability it can go with you almost anywhere and survive to tell the tale The audio quality is punchy and bright enough for what you d expect at this scale and price range Although there s no app support or connectivity with the rest of the Ultimate Ears speaker lineup you can easily pair it with a second Wonderboom for stereo sound There s also an outdoor mode button on the bottom that boosts the mid and high range to help the audio carry over a greater distance Soundcore Motion Bluetooth Battery life Up to hoursIP Rating IPXAux inputs mmFrequency range Hz kHzApp YesThis nondescript wedge of a wireless speaker could easily slip under your radar but it s worth a listen It has a bright and bassy output which is helped along by Qualcomm aptX support for hi res audio This Anker Soundcore device has a solid slightly heavy build with a metal front speaker grille a soft touch rubberized exterior that loves your greasy fingerprints and IPX water resistance While it s not the lightest or most portable the sound is respectable especially for the price Plus the app offers EQ customization so you can fine tune to your liking There s also a mm aux input for wired connections That s fortuitous as we found that this speaker works well as a mini soundbar alternative and the wired input offers a foolproof connection Soundcore Trance Go Bluetooth Battery life Up to hoursIP Rating IPXAux inputs mmFrequency range Hz kHzApp YesIf you have a large indoor space backyard or similar and want something with powerful long throw sound in an affordable package the Anker Soundcore Trance Go may surprise you This barebones speaker is bigger than most others in this price range and would weigh down a backpack a bit at about six pounds but offers a carry strap up to hours runtime a port for charging your devices and an aux input If you re close by you ll hear the thump of its low end and some decent highs It s generally tuned for covering big spaces though and its sound won t work for every situation This performs like a mini loudspeaker putting out up to around dB albeit with a slightly thinner sound that won t overpower the environment You can also use Soundcore s app to apply EQ presets or customize as you see fit If you have two of these they can pair for stereo sound or connect or more Trance Go speakers via the app s PartyCast feature JBL Flip Bluetooth Battery life Up to hoursIP Rating IPAux inputs N AFrequency range Hz kHzApp YesJBL s Flip deserves high marks for overall sound quality durability and volume considering its size As with most JBL speakers it has a good dynamic range from solid lows to crisp highs with volume tipped towards higher registers The cylindrical shape works well on its side or even standing on its end to save desk space It has a capable carrying or hanging strap and raised buttons you can discern in the dark The JBL Portable app gives you a band EQ to customize the sound profile if desired and if you have two Flip speakers you can run them in stereo mode If you happen to have a mix and match assortment of different PartyBoost enabled JBL devices you can connect multiple speakers for a bigger sound Bose SoundLink Flex Bluetooth Battery life Up to hoursIP Rating IPAux inputs N AFrequency range N AApp YesWhile the Bose SoundLink Micro is half the size we found that it s definitely worth the extra if you trade up to the SoundLink Flex While it s still not a room filler the speaker offers some bright dynamic finesse to your tunes along with a significant amount of bass for its size It s similar to the scale of a small clutch bag with a very small strap for carabiner type hanging Much of the exterior is sheathed in soft touch silicone except for the powder coated steel speaker grilles Like others in this range the speaker is IP rated so it can handle the elements and sound good doing it Setup and connecting to the speaker should be done from within the aptly named Bose Connect app You can also turn off voice prompts which can become annoying and pair with similar speakers for either party mode or stereo Note Some users running Android may encounter connectivity issues with the Bose Connect app The company is working to resolve the problem Marshall Emberton II Bluetooth Battery life Up to hoursIP Rating IPAux inputs N AFrequency range Hz kHzApp YesThe recently released Emberton II Bluetooth portable from Marshall has a bumped up set of specs that make it a better value than the previous gen This clutchable rectangular slab still has a pair of watt full range drivers and passive radiators to deliver the brand s signature sound It may not be the loudest in its size range but it focuses more on balanced output than raw power There s still sound as well making it a good companion for small get togethers Although with its hz low end threshold you ll find a better bass response when there are surfaces to reflect off of and not so much if it s in the middle of a table This new model now offers up to hours of listening on a charge hours better than before and a more rugged IP rating There s also a new ability to pair with another Emberton II or Willen II using the new “Stack Mode The range between them is limited however so stacking them probably is the best way to go Additionally Marshall is offering a more environmentally friendly product than before using percent post consumer plastics in its construction JBL Charge Bluetooth Battery life Up to hoursIP Rating IPAux inputs N AFrequency range Hz kHzApp YesIf you re willing to spend a little more for bigger sound longer battery life and a USB C port to charge your devices the JBL Charge is a great upgrade over the Flip It has the same bright output and capable low end but in a slightly larger package If you re looking for a smallish portable speaker but something capable enough to entertain a few guests this works Price to Monoprice SoundStage Bluetooth Battery life Up to hoursIP Rating N AAux inputs Optical mm and RCA plus an RCA sub outputFrequency range Hz kHzApp NoPortable Bluetooth speakers don t always have to be rugged to be good The Monoprice SoundStage is a prime example This portable is a homebody without an IP rating but checks quite a few other boxes Most importantly it sounds great for the price offering a balanced output with respectable low end and clear dynamic mids and highs It has a minimal bookshelf speaker design with a dark gray exterior top mounted control panel which is hard to navigate in low light and a faux leather handle There s a inch concave aluminum cone woofer two inch silk dome tweeters and a rear bass reflex port The SoundStage has a battery life of up to hours with the volume at percent which is fine but not spectacular However it also operates at full volume when plugged in and charging You can also top up your devices with the USB charging port drawing from its mAh battery The other output port is a single RCA for mono analog subwoofer support although it does well in the bass category on its own As for inputs there are a few a mm stereo jack RCA stereo and a digital optical S PDIF Monoprice is known for affordable no nonsense devices with a good deal of utility If you don t need a speaker that s built for rugged on the go action this speaker offers its own flex with great sound quality Bluetooth and plenty of hard wired connections Bose Portable Smart Bluetooth Battery life Up to hoursIP Rating IPXAux inputs N AFrequency range UndisclosedApp YesWe did test a couple smart home speakers including the Bose Portable Smart and I decided to compare it with its closest Bluetooth equivalent the Revolve II While that s best suited for portability has a loud bright sound that will carry outdoors and long battery life its low end is a little less pronounced than its smart companion If you re willing to spend more and appreciate bass the Bose Portable Smart speaker is a big improvement It has a well rounded low end and a bright dynamic sound with plenty of nuance that makes for a great listening experience This degree portable comes as a combo WiFi Bluetooth speaker primarily geared toward smart home use with the occasional outing It s rated IPX so not the most weatherproof but good for casual outdoor listening The battery is rated for up to hours but since this is an always on smart device you ll need to be more attentive at keeping it topped up There s a charging dock accessory for use around the house but as an away from home portable you should power it down when not in use Smart features WiFi voice and app control support for Google Assistant Amazon Alexa Spotify Connect Amazon Music Chromecast built in Apple AirPlay and SimpleSync connectivity with Bose Bluetooth speakers Note Some users running Android may encounter connectivity issues with the Bose Connect app The company is working to resolve the problem JBL Xtreme Bluetooth Battery life Up to hoursIP Rating IPAux inputs mmFrequency range Hz kHzApp YesIf you ve enjoyed any of the smaller JBL speakers out there and are willing to spend a bit more the Xtreme is a good all around choice It s big enough to warrant a shoulder strap but still only about the size of a football There s a pleasant dynamic sound here with hefty lows and a lively high end that seems slightly better balanced at this size than the smaller options from JBL in this range This is easily a favorite if you want something under with a little more gusto than your average portable but still being IP weatherproof It has enough output to breathe life into a small soiree or backyard hang although while it s quite loud it s best when it s close by or indoors where the bass can resonate to its fullest UE Hyperboom Bluetooth Battery life Up to hoursIP Rating IPXAux inputs mm OpticalFrequency range Hz kHzApp YesThe UE Hyperboom is an all arounder with good looks portability plenty of connectivity options and a loud and punchy albeit compressed output The technical fabric exterior which now includes a white option lets it live among your furniture without screaming “party box while the optical input offers a possible TV speaker alternative The large capacitive buttons on top let anyone adjust the volume pause or play the music and select from two concurrent Bluetooth connections or a hardwired input mm or optical On the edge with the silicone carrying handle there are the wired ports plus one for charging USB devices and another for power Battery life is rated for up to hours and the Hyperboom is good at holding a charge on standby This capable and loud roughly dB speaker will please most people as long as the party is of primary concern over fidelity The ability to remotely power your device on or off using the UE app is also a welcome feature Plus you can easily expand the sound to other Ultimate Ears Boom speakers except Wonderboom using the PartyUp feature The IPX rating means a few spilled drinks won t hassle it but it s not the best Bluetooth speaker choice for all weather adventures Marshall Tufton Bluetooth Battery life Up to hoursIP Rating IPXAux inputs mmFrequency range Hz kHzApp NoIf you didn t know about Marshall s history in amplifiers and rock music the design should clue you in The Tufton is the largest portable Bluetooth speaker from the company looking much like an amp itself as do most of them It has physical knobs at the top and a carry strap to help move it about While it may appear as rugged as concert gear it s less impervious to the elements as some with just an IPX rating so it s protected from light splashes from above Whether or not you re a fan of the brand the rich and distinctly thumping output may make you one We felt pulled into the sound while listening to the Tufton a bit more than most other speakers we tested at this scale It s dynamic warm and dare we say analog in its audio presence It s also multi directional with a supplemental driver on the back along with a bass port There s no app to adjust the EQ just the physical controls including a Bluetooth connect button a power volume knob and two for bass and treble Once powered on you can use the volume knob to set a max headroom and adjust volume on the fly from your source The bass and treble knobs help you choose the tone of your adventure from a purely flat soundscape to an enhanced one We just wish you could see the dial indicators in the dark Other features include aptX support and quick charge capabilities that provide four hours of listening time in just minutes plus great standby battery life Price and higherJBL Boombox Bluetooth Battery life Up to hoursIP Rating IPXAux inputs mmFrequency range Hz kHzApp YesIf you re a fan of JBL s smaller portables but want to kick the volume up several degrees higher the Boombox is a good choice This watt plus big brother to the Xtreme provides that familiar JBL sound but you know louder The output has bright and dynamic highs and floor shaking sub bass that may benefit more from an indoor environment with surfaces to bounce off It doesn t have the long throw that “loudspeakers have although to be clear it is pretty loud This is a dance party tool for your basement rumpus room garage hangout beach or poolside craziness The Boombox has a few upgrades from the previous gen The exterior looks mostly the same but it s now IP rated making it very rugged It s also a touch heavier at pounds possibly since this device now has a woofer alongside the mids and tweeters It s still a convenient grab and go speaker for most occasions when you want the music to be the star of the show or at least not disappear into the background The battery can keep you playing for up to hours but it also runs at full volume while plugged in In fact while it s connected to an outlet the total output wattage gets a boost from watts to watts Sony SRS XP Bluetooth Battery life Up to hoursIP Rating IPXAux inputs mm USB thumb drive listening Guitar MicFrequency range N AApp YesSony s big SRS XP Bluetooth speaker is a good option for fans of loud thumping beats The unit has the look of a futuristic stereo speaker at feet tall and about pounds with pleasing lighting effects on the inside of both top and bottom grab bars You ll also find USB charging ports and LDAC support while the app offers customization including light controls The XP remains portable enough for many people to shuffle around locally without too much effort and its IPX rating means it can handle spills and splashes The exterior is hard plastic with some rubberized feet but it s not the type of speaker you want to treat carelessly It s mostly a homebody that can fire up parties in lofts garages basements or backyards You can also wirelessly pair two for a more powerful experience While the sound is big and bassy it comes up short on handling the lowest registers well Also the high end isn t as pronounced as it could be so it may not be for everyone It s more of a loudspeaker style so it s better in bigger rooms and shines at louder volumes Soundboks Go Bluetooth Battery life Up to hoursIP Rating IPAux inputs mmFrequency range Hz kHzApp YesThe Soundboks Go is a top performer if you re looking for a portable Bluetooth option that provides a big sound for larger spaces although it comes at a price This unpretentious black rectangle is half the size of its more professional sibling the Soundboks Gen It packs one inch woofer and a inch domed tweeter both powered by two W RMS amps for massive sound and chunky bass even at a distance At pounds it s fairly easy to lug around and looks about the size of carry on luggage You can even get the optional shoulder strap which helps for longer missions It has a flexible TPE handle on top silicone bumpers around the edges and ABS Polycarbonate exterior and grill The IP rating also marks it as a resilient device in most environments The sound makes a big statement here Output levels are rated at up to dB with clear mids and highs projecting clearly across large areas The low end also has a significant presence at a distance matching up with Hz frequency response It s definitely capable enough to support large gatherings The speaker is easy to connect to via Bluetooth and the partner app offers EQ customization audio profiles and OTA firmware updates There s a solitary mm stereo input on the Go but its wireless expansion shines letting you connect up to five Soundboks Gen or Go speakers at the touch of a button with its built in SKAA wireless support Lastly the battery pack is removable swappable and also long lasting for a speaker this size at low to mid volume it s rated at up to hours runtime For transparency Soundboks also lets you know to expect around hours of play at full volume You can also run this while charging but there are strict warnings about keeping the volume low while doing so it s not recommended unless you re desperate	2023-01-13 14:30:22
