I have bought 5 Flex speakers over the past few years there the best speakers I've ever owned Bose is top of the line in sound and has been for decades.
I must say this speaker FILLS an average bedroom with wonderfully clear loud but not loud music this speaker absolutely worth the cost definitely recommend the purchase
Sound is very good. But I bought the speaker to pair with the SoundLink Flex Portable Speaker I already had. So far I have found them to be incompatible. The phone app does not work the the 2nd Gen either. Very disappointing.

Thanks for your feedback. The SoundLink Flex 2nd delivers big, bold sound in a super‑packable design and is built to go wherever the music takes you. I’m sorry the SoundLink Flex 2nd Gen didn’t pair with your original Soundlink Flex first gen and the app didn’t work as expected. The two generations use different apps, SoundLink Flex 1st Gen uses Bose Connect app while the 2nd Gen uses the Bose app, so they are not compatible for stereo or party pairing.

In comparison to my Bose Soundlink II that I purchased quite a few years ago, the Second Generation lacks the superior sound quality of my original Bose purchase.
