Customer Ratings & Reviews

I’ve been using the Bose Soundlink Flex II for a little while now, and honestly, it’s quickly become my go-to portable speaker. Right out of the box, the setup was super easy – it connected to my iPhone in seconds, and I was ready to play my music. For such a small speaker, the sound is amazing! It’s got this rich, deep bass that you wouldn’t expect from something so compact. Whether I’m listening to music or catching up on podcasts, everything sounds crisp and clear. Plus, if you really want to step it up, the Bose app lets you link two of these speakers together for an even bigger sound. Perfect for a small gathering or an outdoor hangout at the park. Speaking of outdoors, this thing is built with that in mind. It’s both water- and dust-proof, so I don’t have to worry about it getting wet by the pool or dusty when I take it camping. It’s tough and portable, but still stylish enough to leave out in the living room. All in all, the Bose Soundlink Flex II is a quality speaker with serious punch for its size. If you’re looking for a portable speaker that delivers big on sound and durability, this one’s a winner.

Specs This is a very durable and portable speaker made by Bose, who really know their audio items. The size is right around 2” x 8” x 3.5”, yet it still produces the best sound across the board of any speaker I own. There are several different modes it can go into, including party and stereo modes, where you can connect two of them at once for a better surround sound by achieving both left and right channels. The battery life is quite long at 12 hours and charges easily with a USB-C cord. Bose also has an app that can be downloaded to control the speaker and tweak the sound. Pros Talk about durability! I don’t worry about it too much packed up with my gear because it’s water- and dust-resistant. The small size keeps it portable in most situations and wireless Bluetooth connectivity makes it easy to control. The app has very user-friendly controls but it’s not necessary to use the speaker. Cons 12 hour battery life is decent, but it takes up to four hours to charge it completely. For someone who usually forgets to plug in their electronics to begin with, this can be a problem. Although it’s durable, I’d also like a carrying case to prevent unnecessary scratches and whatnot from potentially rough traveling conditions. Conclusion You can’t beat this sound for this price through Bose; this is an affordable option for those who are sick of the tinny sound portable speakers usually carry. You’ll get clear and powerful sound through any genre of music!

The Bose speaker delivers rich, clear sound with impressive bass for its size. Audio remains balanced even at higher volumes, making it perfect for both indoor and outdoor use. The build quality feels premium, and the design is sleek and modern. Bluetooth connectivity is fast and reliable, and the battery life easily lasts through long listening sessions. A great choice for anyone who values sound quality and durability.

Impressively clear, balanced sound — For its size, this speaker delivers clean, detailed audio that handles vocals, acoustic tracks, and everyday listening very well. Midrange and treble are crisp and lifelike, giving music a natural, pleasant feel. This makes it a great all-around portable speaker for home use, travel, or casual listening. Strong portability & build quality — It’s compact, lightweight, and easy to carry around (ideal for small apartments, travel, or shifting between rooms). Yet it still feels solid and well-built, with a design that balances sleekness and durability. Reliable battery and wireless convenience — Built-in Bluetooth connectivity makes pairing with phones, laptops, or tablets simple, and the rechargeable battery ensures you can use it unplugged for extended sessions without worrying about cables. Great value for daily use — For people who want a no-frills, dependable speaker that sounds far better than most basic Bluetooth speakers, this model hits the sweet spot: quality sound, ease of use, and portability at a reasonable trade-off compared to full home audio setups.

I’m extremely happy with my purchase of the Bose SoundLink Flex (2nd Gen) in Blue Dusk. The sound quality is impressive for such a compact speaker—clear vocals, rich mids, and surprisingly strong bass without distortion, even at higher volumes. The build quality feels premium and durable, and the waterproof/dustproof design gives me peace of mind whether I’m using it at home, outdoors, or while traveling. Battery life has been solid, and Bluetooth connection is fast and reliable. I also love how portable it is—easy to carry, lightweight, and stylish. Overall, this speaker delivers excellent performance, durability, and design. Highly recommend it if you’re looking for powerful sound in a portable package.

This is a great product. Clean sound. It can be heard even in very large places. I had to bring it to work on a day that electricity went down. I have used as a substitute to professional sound equipment. And no one saw any difference. I generally use it for home.. it is great for low gentle loung music or loud as a disco club. The quality of sound doesn’t change. It reproduces sound as in a professional entertainment, I didn’t need to recharge the battery since Christmas yet. Also, my house got flooded and one of the two speakers I bought went under water. I saved them both after that and when I tried to turn it on again, it seems to work! Unbelievable! Really good!

It is honestly astonishing how big the sound is coming out of this compact gem. I don't know what engineering voodoo Bose is using, but their speakers blow everyone else away in terms of audio balance. There's bass, but it's never overpowering. There's treble and it's never tinny. If I want to hear a song played well, this is how I play it. The fact that it's so small and lightweight (and water resistant!) means I can pick it up and go anywhere in the house, or throw it in a suitcase. And for the price, you can't go wrong.

The Soundlink Flex II is another quality product in Bose’s lineup. It’s built well with a silicone cover that’s durable, but also soft to the touch and easy to clean. Buttons are well protected and provide nice, tactile feedback with every input. Battery life is good and it charges quickly via USB C. Bose provided a USB C to USB C cable in the box, but no charging brick. Sound quality is good, but generally even across all genres. Seems to be best at ensuring clear vocals. The Bose app does give you some customizability by allowing you to play with EQ settings. The app also allows you to quickly change device connections, customize the speaker’s shortcut button, and access software updates. Since getting my speaker, I’ve taken it out on the boat and been using it while working on my project car. This single speaker got plenty loud while we were boating. It survived multiple hours in direct sunlight, being tossed around while under way, and being thrown in and out of the water. A full day of use went through about 40% battery at fluctuating volumes. I’m contemplating purchasing a second one and making mounts for them to rest in. We’ll see. The other day I had my speaker with me while I was repainting body panels on my car. Paint and dust makes its way onto just about everything while doing this. I was extremely impressed by how easy it was to clean this speaker off. One disinfecting wipe did it and it looks good as new. All in all, I am very happy with the Bose Soundlink Flex II. I feel like it’s a good value for a name brand, durable, and portable speaker. As long as it’s the right size for your needs, I’d absolutely recommend it.

It’s a Bose, so as you might expect it sounds great at low, mid, and full volume. It’s waterproof, sand / dust proof, and shock proof which I love in a portable speaker. It feels solid and well built. It has a built-in strap that seems durable and lets you clip it to backpack, etc. (clip not included.) The Bose app is simple to use. It also gives you EQ options with some preset options (Bass Boost, Bass Reducer, Treble Boost, Treble Reducer) and you can manually set Bass, Mid, and Treble up/down 10 each. Personally I think it sounds best at Bass +8 and Mid +2 settings for a deeper sound. I put it through the paces on every musical genre and most sound great (rock, rap, dance, folk, country, classical, etc.). Bass heavy music I’d love a tad more bass, but that’s difficult to achieve in such a small package. It sounds good whether laying down, upright, or hanging from its strap. Buttons are easy to use and intuitive including a configurable shortcut button (Link mode/party mode for combining with another Bose SoundLink Flex, Access with Voice Assistant, and Spotify) It has multi point connection to connect with 2 different BT source devices. Battery life is rated at a solid 12 hours, but likely depends on the volume you’re jamming out at. Charging is thankfully USB-C. It weighs about 1.5 pounds so it’s light, but not a featherweight. Overall a solid, rugged, great sounding portable speaker.

The speaker is compact enough to hold in your hand, tuck into your pack, or attach to the outside with its sturdy utility loop. The Flex 2 boasts a 12-hour battery life and an IP67 waterproof rating. With advanced Bluetooth 5.3, it ensures a robust, uninterrupted connection to your device from up to 30 feet away. Multi-point connections allow the speaker to be paired with several devices simultaneously, facilitating easy sharing of DJ responsibilities with friends. A notable addition is the Shortcut button, which provides quick access to various functions, including instant pairing with another speaker. Whether standing upright, laid back, or hung upside down, the SoundLink Flex consistently delivers optimal sound. Bose's PositionIQ technology detects the speaker’s position and adjusts its output for the best performance. Bose speakers are known for their agreeable sound, and the latest SoundLink Flex is no different. It offers clear sound with surprisingly good bass for its size, and the volume can reach impressive levels. Vocals come through clearly, and overall, the audio quality surpasses expectations for a speaker of this size. The accompanying app has been updated recently, allowing EQ adjustments through the Bose app. It also facilitates "SimpleSync" pairing with another compatible Bluetooth speaker. In Stereo Mode, one speaker serves as the right channel and the other as the left, while Party Mode synchronizes two speakers to play the same audio. The Bose SoundLink Flex (2nd Gen) Portable Bluetooth Speaker delivers exceptional sound in a compact form, embodying the quality I value and expect to last. It meets all my criteria for a portable speaker, and I would highly recommend it to anyone seeking a top-quality small Bluetooth speaker.

This Bose portable speaker is one of the best portable speaker I ever had . It’s so easy to use, just connect to your Bluetooth device and listen to your favorite music on the go while caring this compact speaker every where you go I even clip it to my backpack. The crystal sound and deep bass of this speaker is amazing just like I was expecting from a Bose product. The battery life last me all day while I care it to the beach without the need of charging it until I’ve got home. This Bose speaker is also dust, waterproof and one cool thing about this speaker, it also floats if you ever drop it in the water, you can also connect another Bose sound link flex speaker with the press of the shortcut on the device to make a stereo sound effect. The speaker can be lay flat, stand up or just hang it anywhere and with the Bose app you can adjust the sound the best way you like for an amazing sound. On the top of the speaker you get the power button, Bluetooth connection button, shortcut to connect more speakers, the play/ pause button and the up- down volume, it also have a built in mic that let you take calls. Using the Bose app helps you monitor the battery life, adjust EQ sounds, adjust volume or change shortcuts to the speaker.

The new Bose Soundlink Flex 2 is Bose through and through. The build quality is the equal of the Bose reputation. And the sound quality? Equally impressive. I have owned a number of Bose products since purchasing a pair of their 901 Direct/Reflecting speakers in the mid-80s. Since then I have owned several of their remarkable headphones (currently on the first Gen of their QC45!) a pair of their excellent AM-5 speakers (with stands) and over the years I have given as presents to friends and family, several models of Bose headphones and Bluetooth speakers. The Flex looks and sounds like a Bose should. "Bespoke" is a term that has come into favor recently for use in reviews most often typed in "dulcet tones of reverence". The Flex 2 deserves better praise through prose, if you will. As I said, it is undoubtedly a Bose product. First off, it looks like a Bose and as you would expect from Bose, it PLAYS like a Bose. During my testing the battery lasted on average just over 10.5 hours of constant use. The volume was set at an acceptable "I-am-sitting-right-next-to-it level". The same volume level worked perfectly across a 10' X 15' room. I played it as loud as I could personally take it and there was no shortage of music without annoying distortion brought on by shoddy construction! I then moved to the largest anechoic chamber in my home. That would be our backyard and here (hear?!) the Flex 2 continued to amaze rather than amuse with its excellent reproduction of the soundtrack of my life. Even acoustic Jazz with relatively deep bass was done well by this small speaker! The range of reception for the Flex 2 in my testing was for up to 40 or so feet (approx.) from its playback source. Using my iPhone as the source resulted in the best reception as my 3 Digital Audio Players are all several years old and as such their Bluetooth versions are far earlier and not nearly as stable at longer distances as the iPhone 14. It should be noted that this is NOT the "fault" of the Bose Soundlink Flex 2 but rather the limits of earlier Bluetooth transmit variants. Still, the signal was received and decoded with nary a real problem and that is something to consider in the real world in which we all live. The Bose Soundlink Flex 2 delivers your music with ease. I am retired now and as such spend a great deal of my days listening to music and the Flex 2 worked great with either my iPhone 14 or any one of my 3 Digital Audio Players! What more could one ask of a modern Bluetooth Speaker? Answer: Nothing really. The Bose Flex 2 is a quality built speaker with modern good looks and sound quality that goes beyond the level of just being "loud". But when it comes to satisfying sound this speaker goes to "11". Highly recommended? Indeed!

It’s pretty loud and a good size. Price-wise it’s mid — you might find something better in the same range — but overall I’m not disappointed. Battery lasts pretty well, and being able to link up to 2 speakers is a nice feature.

I love this speaker. The color, the bass, the sound, the size. I bring it everywhere with me and even use it at night with the Calm app's thunderstorm sounds to fall asleep. The bass on it makes the thunder feel real. Lol overall, great purchase.

Just got my hands on the Bose SoundLink Flex, and honestly, I’m impressed. For something this compact, the sound is way bigger than I expected. The bass hits nicely without overpowering the rest, and the clarity stays sharp even when the volume’s cranked. One thing I love is how rugged it feels. I’ve already taken it to the beach and tossed it in my bag a few times no scratches, no issues. It’s waterproof and it floats, so I don’t even worry when it’s around water. Perfect for summer hangs. Battery life has been solid, I’ve gotten around 12 hours out of it without needing a charge. Super easy to pair via Bluetooth, and it stays connected without dropouts.

Unsurprisingly to most people this speaker is amazing. Obviously, i mean, it's Bose. They are the undisputed champs of the audio tech companies in my humble opinion. I took this speaker on vacation and it withstood hours of the extreme Jamaican sun, sand, salt water, and occasional spill of a frozen strawberry margarita - and i only charged it once the whole trip. I don't wanna toot their horn because their products are typically on the pricier side, but in this case i can really say confidently you get what you pay for. The sound quality is crisp and clear and the bass is booming. The rose pink color and its compact nature is really just a plus. All around great product and i have no doubt it will last me several years or until i just decide to get a new one. Side note: i'm also pleased with my buying experience with Best Buy. i needed this speaker pretty quickly but the first delivery got messed up. But a quick chat to customer service and i was able to get a replacement sent no problem. I really appreciated that and it made me want to purchase more items through best buy.

I love this speaker. I have bought a few other Brands , that was cheaper, but you get what you pay for... Amazing sound from such a small compact speaker , with amazing Bass..it Is a little expensive , but I got it in sale for only $99..Had bought it in the Sandstone color, which was very nice, except the buttons were hard to see . grey in color , with lighter grey colored buttons... Difficult to see... On the light ones.. The buttons Should be Black.. I returned it for the Black one which Is much easier to see....

Perfect portable speaker. Great sound, light weight, good connectivity and battery life. And got it at a great price during the pre- Black Friday sales!
