Customer Ratings & Reviews

I purchased the Bose SL Flex in Late November 2022. Best Buy had all the Bose Bluetooth speakers lined up, and I was able to compare each speaker side by side. I was really impressed with the sound quality of the Flex. I also own the Bose SoundLink Color II which I purchased back in 2020. When I brought the Flex home and then compared the sound quality of the Flex to the SLCII, there was no comparison. The Flex has much more bass and projects much better and fuller sound than the SoundLink Color II. You can keep going up to the more expensive Bose speakers, but I think the Flex checks all the right boxes - for the price, sound quality and clarity, and much more durable build quality. Plus, I prefer the design of the Flex versus the other Bose cylindrical speakers. I want to give this speaker 4.5 stars. One critical area is that the Bose Flex doesn’t have any type of Equalizer app where you can change/enhance the sound quality with different music. Many other brands are offering an EQ App with many of their Bluetooth Speakers. You could say that Bose Speakers are optimally tuned where you don’t need this feature, but it still would be a great option to have an EQ. One good thing to mention is that I regularly use the Bose App on my iPhone to pair 2 Bose speakers together - the Flex and the SoundLink Color II. Pairing both of these speakers in stereo mode is very easy, and maintaining the stereo mode is overall stable. I listen to a lot of classical, old rock/pop music from decades ago as well as a good amount of R&B, Jazz and Blues. I also own a few other Bluetooth speakers besides the Flex, including the 1st Gen Marshall Emberton, and a few others, so I am very selective about sound. I’d definitely recommend the Flex.

Works great. Nice and loud with bass. Great purchase

I love Bose, for the price it's great. I still get better sound quality and volume out of my Bose SLI II but this model is more mobile. I clip it on a carabineer and hang it from my waist or mirror daily. Battery is good, it lasts a full shift and drive time to and from, charged every night.

So far I've had this item for almost two months and I'm very satisfied with it. I mostly listen to rock music with it and on occasion punk, never tried other genres yet but I am sure it would do fine. In terms of volume its not too bass heavy but I personally don't need that and the quality of audio is very good. This item is a huge step up over the Waterbox portable speaker that I had in terms of quality and speaking of which the battery life on it meets my needs, I never timed it but I always get good amount of use out of it before having to charge, your mileage my vary through your own person use ect . To sum it all up I highly recommend this purchase if you're willing to spend a bit more to give yourself something that isn't too bass heavy and has a good amount of battery life along with good audio in my opinion.

I love the sound of the speaker and it bumps really well. It’s durable and sound is amazing. I just wish you could control sounds like treble and bass in the app and kinda customize how you like to listen.. but overall it’s better than all the others and battery life is like forever lol

What a great product. Connecting to phone and Apple iPad was real easy. Playing my various Playlist was fun, but the best was the sounds that come out of this small package are amazing. Plenty of bass and clear vocals. Instant party. Well worth the price.

It was my son Birthday present. It has a very good size also quality sound

Amazing speaker. Easy to hang in places and doesn’t take up much space. The sound output is high quality and it talks to you telling you who’s connected and the battery percentage. Well worth it

This speaker may look small, but it has EXCELLENT sound. It delivers heavy bass that you can feel, and very clear highs. It also gets really loud, so it's perfect for parties or events. The bluetooth connection is instant. Truly the best portable speaker you can buy!

I recently got my hands on this Bose speaker, and let me tell you, it's like having a tiny music wizard follow me. This thing is so powerful for how small it is. The sound quality is amazing and the battery life is impressive too lasts well into the night without worrying about the speaker dying on me. Definitely a great device to carry.

amazing speakers, sounds quality stays the same all the way up! Durable, waterproof, also has good bass. only feature that’s needs added is allowing more than 2 to connect to each other!

Portable, tiny yet surprisingly powerful. It's a party whenever this is playing--I love it and highly recommend.

Great sounding speaker. Connects easily to phone. The charging chord could be longer, but the speaker has a good battery life and is easy to travel with.

A small beast! Great sound great product neat design.

You simply have to listen to this speaker to believe how much room filling volume and rich bass it produces. I knew as soon as I heard the demo unit in the store that it was the best value for the money. Battery life is excellent. I'm considering purchasing another to pair them for stereo sound.

Excellent sound, very portable, good battery life, small device

Love it. Easy to use. Small and compact. Great sound and lasts.

This is a great choice for a portable Bluetooth speaker. Powerful bass, clear crisp highs. Easy to carry and set up. You can also connect two together for full stereo sound. Long lasting battery too. What more could you want?

My mom has one of these and its amazing so I decided to get one myself. Love the sound quality despite its compact size. Its great that its waterproof, I use it inside and outside

This speaker has fantastic audio, crystal clear sound and good bass for how small it is. Prior to purchasing this speaker I had been using the original Bose Soundlink Mini (1st Gen). Hasn’t given me any issues after all these years but I thought it was time to upgrade to something new and improved. Glad I did, much louder and fuller sound. May even purchase another in the future. Great job Bose, another great product!
