Great speaker and battery life is good , Bose did not disappoint I would recommend

Good speaker, sounds good. Quality that I’d expect from Bose.

Of the wireless speakers that have the best sound that you can find in the market!

Great sound quality. Bummer it doesn’t support Apple Music Lossless.

Sounds decent and gets loud. But the different parts of the music get lost and just mix together. I missed the return window and if I could I would return it. There is also a noticeable dead zone in the sound that can be played by the main speaker and what is played by the bass speaker. At least it has great build quality.

This is a competitively priced, high quality speaker in a crowded market. This speaker is durable, and way louder than it should be for its size (without sacrificing clarity). Bose could have rested on its laurels and slapped a Bose label to any speaker and turn a profit, but it’s clear that’s not the case. IN THE BOX The box in some respects seems smaller than the speaker. Other than the speaker you get a USB-C cable for charging (thank you Bose for moving to USB-C). SETUP I typically charge my new products straight out of the box, but this speaker had about 30% battery life out of the box. Either way, setup is as simple as connecting any Bluetooth device to your phone. You simply hold the power button for a moment, then push the Bluetooth button to go into pairing mode. Then follow your phone’s steps and you’re connected. Now you could stop there, or you can go the extra mile and download the Bose Connect app. I didn’t, because I like to limit unnecessary apps on my phone. I’ve used Bose Connect app before for my QC35 headphones (which is how you update the firmware). It gives you a little extra functionality which I’ll discuss in a moment. DESIGN I’m actually mixed on the design. I have the black model and it looks pretty darn basic. But some people might find that appealing (simplicity). And I was also a little torn on the “rubber” coating. It actually feels good to hold, but it just captures weird smudges on it (as you can see in my pictures). This probably will be of little consequence to most people and shouldn’t really affect your decision to buy it. But then, when I learned a little bit more about the coating, I came to appreciate the design, not for the looks but for protecting the speaker itself. This is labeled a durable speaker mind you. The back is a silicon, while the grille is metal and powder coated. Then you realize it’s dirt, water and dust resistant. So yes, you can use it on the beach or at the pool. Heck, it even floats (so they say, I’m reluctant to test that on purpose other than my bathtub which I haven’t done). So, when taking into account the design, there’s more to the Flex than looks. It’s meant to be taken on adventures. I also need to mention that it’s light, around 1 pound. SOUND PERFORMANCE I’m no audiophile, but I can certainly tell the difference between “puny” or “tiny” sounding speakers, and the “clarity” “range” and “bass” in others. This Bose speaker is remarkable for how loud it gets based on its size. It’s truly deceiving. And the bass, man it packs a wallop. All while producing crisp highs and midtones. From listening to podcasts, to rap music to country, I thought it all sounded wonderful. It won’t drown out a large room of people, but if you are outside or in a room with a few people hanging out and listening to music it will do the trick. One of the cooler features is that Bose has some technology in that adapts the sound depending on its orientation. What do I mean? Well, the speaker can be placed on its back (speaker grille pointing up), on its bottom (like a traditional speaker, pointing the grille in a certain direction) or you can hang it by the utility hook and it will be vertical. So the speaker adapts depending on its orientation to deliver the best sound depending on its position. This sound “optimization” if you will seems to work great because you don’t notice it. Meaning, depending on the orientation you get the same sound performance. MISCELLANEOUS The one area where this speaker falls a little short in my opinion, is battery life. It’s rated at 12 hours for medium volume. This I’m sure is plenty for one time use. But I often use my speaker here and there and don’t always charge it in between. I have a Sony Bluetooth speaker that delivers 24 hours of battery life. But that speaker is larger and much heavier, so the trade off is well worth it. Bottomline is that battery life shouldn’t be an issue for most, but some speakers deliver longer battery life. It has some other features, like connecting to other Bose Flex speakers to mirror the sound, or create a stereo (L and R speaker) effect. I haven’t tried this out because I only have one Flex, and I don’t see the point in buying two just to do that. But I guess if one of your friends has one, it could be useful. I don’t want to say that’s a gimmick, but it’s not a big selling point for me. This is meant to be a speaker you throw in your bag to go on a camping trip (or something along those lines). It can also connect to Bose soundbars, but I’m not quite sure why you’d want to. Satellite speakers I guess? Last, you can control your phone’s audio assistant and take phone calls. I don’t generally take any calls over Bluetooth speakers (preferring headphones for that) but I’m certain some people will like that feature. I haven’t tried it out to determine the quality of calls, but I’d imagine it’s solid. CONCLUSION For all the features or things this little speaker can do, it’s just icing on the cake. You don’t need them to justify the purchase. At $149, this is (not cheap by any means) reasonably priced speaker that delivers amazing sound quality, especially given its size. Its durability and IPX ratings means that it should handle the daily throws, drops, bumps that are a part of everyday life and keep on chugging.
