U Boost Speaker | Stylish Portable Wireless Bluetooth 5.0 with Built-in Subwoofer and Mic | Perfect Mini Speaker for Home, Parties, Travel! Small Device, Rich Sound | Hematite

The sound isn’t as clear as bigger portable speakers in this price range. But the bass on these little guys really thumps. And two of them are much better than twice as good as one. And these are literally pocket-sized, so you can take them anywhere, and arrange them and rearrange them to your ears’ content.Battery life is not great. And connecting two of them to an iPhone is neither intuitive nor quick and easy. But if you follow the instructions, and don’t mind waiting a few seconds, they will pair with your Bluetooth source and each other and give you real stereo sound.Bottom line: a pair of these is more than the sum of its parts.Supplement: They’re fragile. If it it’s the floor, the screen pops out. I had to return them.

For a little itty-bitty speaker this has awesome sound. Another thing that is cool, it also serves as a speaker when on the phone.

I saw this on vacation at a store gift shop. They had it playing. Nice sound with built in sub woofer. Heavy speaker, really haven't compared to other Blu tooth speakers.

I had an old Sony speaker that my new computer wouldn't even detect. I spent an hour with Apple Support, where I went through all the diagnostics and was assured that the problem was the speaker was too old. After reading positive reviews of the U Boost speaker, I ordered it to replace my old one. It looks cute but it didn't work with my 2020 MacBook Air. At least the computer detected it, but it would connect for an instant, play from the speaker, and within a second disconnect. I thought maybe I'd received a defective product, so I returned it and received a new one. The new one was weirdly worse. It would show up as "connected" in my computer but the music still plays from the built-in speakers. I tried to change the sound output in system preferences, but the device doesn't show up in my device output options. I guess I'll try a speaker with a more familiar brand and update this review if that one doesn't work either.

I love this tiny speaker for travel. The sound quality is amazing in such a tiny package. I like it as much as I like my Bose Bluetooth speakers that cost 3 times as much.

I loved the size and sound quality...couldn't beat the price for that!

Pretty shocked the quality that comes out of this little thing. Definitely recommend

Love these little speakers! Sound quality is awesome!

Great sound and love that it fits in my hand. My phone was outside and I walked around in my house with just the speaker and it didn’t cut out once. That is amazing to me.

Its a nice speaker, just don't like that the hematite version is a fingerprint magnet, and the battery life is probably around 3 hours not the 5 as advertised, other than that it is pretty good.
