Ratings and Reviews

Rated 5 out of 5 by from Durable and User-Friendly The Bose SoundLink Flex, true to brand, has amazingly powerful sound for its small size and is packed with thoughtful features.  This model is built for adventuring, particularly with friends.  Don't let the size fool you; this is a party speaker.  It can even connect with other portable Bose speakers in cases where you want more coverage. The battery life is enough to keep your musical motivation going through a full day of travel.  I was not able to charge my phone from the Flex as with its larger cousin the SoundLink Max, so don't expect it to double as a power bank if that is a priority for you.  In terms of size, this is a Goldilocks speaker.  It won't fit in your pants pocket (though you can carry it in the kangaroo pocket of a hoodie), and I wouldn't take it on ultra lightweight backpacking trips where every ounce counts, but it's just the right size to hang off of a pack and take camping or boating.  It's also perfect for beach or pool parties where you want a solid sound system that can stand getting wet. As someone who does a lot of outdoor adventure travel, this is the long-wearing speaker I've always wanted.  While the price point makes it an investment that I would normally think twice about risking on rough trips, the Flex is durable enough to withstand rain or hard bumps, and the sound quality is worth the cost.  The built-in webbing loop makes it easy to hang from a hook or carabiner, and I feel confident hanging it from a backpack without having to fret about it bumping around.  The loop itself isn't replaceable but seems durable enough to last.  The silicon coating can pick up dust, but it's extremely easy to clean due to the water resistance; just give it a rinse.  It even floats so can survive an accidental plunge with no rescue diving required! There is almost no learning curve but plenty of options for customization through the app.  It's extremely easy to connect to devices or other speakers via Bluetooth, adjust the EQ, and set a shortcut.  There aren't many buttons to learn, but you can make it yours within about five minutes of opening the box.  I'm the kind of person who listens to music a lot, because it makes everything- even homework or housework- feel more epic.  The Flex works for that just as well as for true, outdoor adventures.  So, if you want your next excursion with friends to have an epic soundtrack, this speaker is a solid choice!

Rated 5 out of 5 by from Mighty Flex Speaker Considering how small this speaker is, it truly does pack a big punch. Being able to comfortably bring a speaker with me on outings, especially one that can be clipped onto a backpack is game changer. The speaker quality is very clear, and handles deep bass sounds very well. You can easily adjust the EQ to your liking on the app which I found very pleasing. The sound progression is very clean, it doesn't jump too high as you increase audio either. My only issue with the speaker as of now is the connection for bluetooth can be a bit spotty, which can be fixed with an update to the speaker. Overall, this is a great product.

Rated 5 out of 5 by from My New Sidekick The Soundlink Flex2 has become my little sidekick. Im all about quality sound & love to have something always playing as I go about my day. From music/podcasts to videos/tv - The Flex2 is PERFECT for anything. Not only is in insanely portable. It emits the kind of sound quality that’ll make you think you’re listening to a stereo system. Like seriously, how did they fit all of that power into such a little rectangle? Lol On the other hand tho- with the ability to adjust the EQ settings, if you want to be quiet about your listening. YOU CAN DO THAT TOO!! Just adjust those settings to lower & you’re good to go - personal concert at your fingertips. Hahaha. For real though, I listen to music all the time while my family sleeps & I’ve never heard one complaint. The sound versatility is out of this world! & while it is an overall fantastic device, I will say that it does seem to tip over backwards if not set down properly. Just something to note. Overall, I give the Flex2 is a 10/10, 5 stars, 99% (docking 1% for the minor stabilization issue cuz it’s not a deterrent by any means) & a solid TWO thumbs up! It’s a solid speaker choice for anyone wanting access to great quality sounds without breaking the bank or your wrist (hahaha)

Rated 5 out of 5 by from Huge sound for a small speaker I have a different "portable" speaker from another competitor and it's not even close. The one i previously used was so much bigger and heavier, this little speaker really packs a lot into it and is so light! The sound quality is definitely Bose quality theres a richness and fullness in it. I was concerned about 360 sound but even behind the speaker it was loud with good quality. The only thing I would add is a slip case for when I throw it in a backpack, it'd be nice for it to be protected and have the charger with it. I do love the chrome/metal finish to it, but I can see that getting scratched as I bring it around.

Rated 5 out of 5 by from Perfect Size I have had this speaker for 2 weeks now. The sound quality out of a speaker that is so easy to carry with me is my favorite part of it. As a college student I spend a lot of time outside doing different things with my friends. This is the perfect speaker to bring with for adventure. Personally have taken the speaker fishing and hiking and it is so nice I can clip it to my backpack and go.

Rated 5 out of 5 by from Small Body, Big Sound! I am extremely happy with the SoundLink Flex Portable Speaker! I have used the product in a variety of settings (indoor/outdoor) and was very impressed powerful the sound is no matter where I’m listening. I love the ability to adjust the EQ in the Bose App in order to find the sound that I prefer. Connecting and switching between Bluetooth devices is quick and seamless, a welcome relief from other products I’ve used. The materials give the product a premium feel while maintaining a sense of confidence in its durability. It is small enough to transport with relative ease, especially if attaching to a bag or similar item using the built-in loop with a carabiner. One thing that I do think would be interesting would be the ability to sync the product with other speakers within the SoundLink lineup. Whether you prefer soft instrumental music, strong bass, audiobooks, podcasts or a little of everything, you will not be disappointed with this product! I look forward to using mine for a long time!

Rated 5 out of 5 by from Little Big Sound I have had Bose SoundLink Flex for a few days now and despite its compact size, the SoundLink Flex delivers clear and deep sound, with surprisingly powerful bass for a small speaker. SoundLink Flex is easy to carry and fits effortlessly into my laptop bag. I got well over 10 hours of listening time on a single charge, I easily paired the speaker with 4 different Bluetooth devices and pairing was simple and seamless. My only concern was with the Bose App While the speaker connects to the Bose app, it doesn't offer as many sound customization options (EQ, etc.) and the app feels a little glitchy and not very user-friendly. As somebody with multiple Bose products, I can confidently say SoundLink Flexis is a solid option with excellent sound quality, portability, and durability.

Rated 5 out of 5 by from Great Speaker! I got this speaker a few weeks ago and although it’s small it really packs a punch! The bass is phenomenal, and I think the audio really can get pretty loud. This speaker is pretty easy to take around with you and the battery life is pretty great too. I have another Bose model and I really think you can’t go wrong with any Bose product. Pros: -size: easy to carry and bring places -sound: great bass -battery life: decent amount of time in between charges Cons: -doesn’t have a premade carrier handle strap, but can attach a carabiner to make it easier to carry

Rated 4 out of 5 by from Toddler Dance Parties! I’m a busy work from home dad with two very active toddlers at home. The speaker is perfect for moving around the house anywhere work or kids take me. In normal Bose fashion the quality of the speaker is darn near perfect. The small speaker is a great catalyst for lots and lots of toddler dance parties. There is no real perfect product and there are a few things that this speaker does well, and a few not so well: - Pros - great compact design; the small design makes it perfect to maneuver wherever great sound is needed - Party mode!!! Having the ability to link to another sound link speaker is awesome! - Cons - The way the product sits upright it falls over with just a little bit of shaking, played it a lot laying down - No cover on the charging port (with little kids around they may try to put something in the port) - The material on the outer cover is a rubber like material that shows dust really well Takeaway: If you want a high quality speaker at an affordable price this is the speaker. Other than a few minor inconveniences this product delivers on all levels like all Bose products do.
