Super quick and easy to connect to my Apple devices
Great sound and tried the App and … won’t let me adjust amount of bass response. Boo. Doesn’t take much space on my desk and is quite easy to use. Love this color!

Sound is amazing!
I love the color of this blue one! Music is amazing out of this speaker. I like bass and it has plenty! I havenât tried using it with an audiobook so I donât know if the base will be too much in that case but it freaking rocks when jamming to your favorite tunes. The sound is crisp and it will get quite loud and Iâve not even turned it up 75% yet.

Overall very nice
Nice compact design. Simple to sync to my iPhone and easy to use. Very good sound for such a compact design.

Sounds excellent!
I use this speaker all the time. It’s great to bring around with me when I’m working around the house. I got a second one to pair them together. The battery lasts a long time, it’s easy to charge, and, as an audiophile that is constantly listening to music, I love that I can take this outside while I garden or have it in my bathroom or do anything, really.

Battery life not what reported
Love the sound, but battery life is SHORTER than my first UE Boom, and UE Boom 2. This was 2 hours versus claimed 15 hours. An AI quiry-response says “it’s a high volume” issue. Not true! My UE Boom II has a longer life by about 5 hours at it’s max volume. This one was 2 hours (!!) at high volume when it is advertised for 15. That’s just bull…and false advertising! Don’t get me started on the false advertising for price (amazon doubled it, and took 1/2 off for Black Friday deal, but on UE Boom site, it’s $129 full price, marked to $114).

Decent Speaker – Weak Connectivity
When the speaker works, it is pretty good for the overall size. It has issues with interference while playing music which is amplified when you connect another speaker via the app.

It’s a great speaker, but…
It’s a great speaker if you’re a podcast listener. Sound and quality are top notch. However it fails when it comes to music. There is absolutely no bass. If you’re like me when it comes to music, buy a bose.

better than jbl
more durable and complex sound than the flip. even better now with usb-c as opposed to micro-usb on the predecessor

Fan of Ultimate ears. This Boom 4 is super good for a bed room speaker. The quality is good, the clarity us crisp and the bass is noticeable. 5/5 product.
Amazon Customer –
Great sound from this little portable speaker! Super easy to useâ¦if I can do it anyone can!

I had a wonder boom one and it got lost sadly. The last one lasted 7 years before it was stolen or lost. This one is sleek, doesnât make the obnoxious power up noise the other one did. Update: found the old wonderboom and compared sounds and old one sounded better. Sent this back for a refund.
