Black Friday deal made this a really good Bluetooth speaker for the price. Sounds great, top 90% of volume loses clarity.
The Ultimate Ears BOOM 4 is a fantastic portable Bluetooth speaker. 1 Its rugged design, powerful sound, and impressive battery life make it perfect for outdoor adventures, pool parties, or simply enjoying music at home.

Not worth the money

I originally bought this speaker thinking I would use it for a small outdoor gathering. Thank goodness I tried it before I wanted to use it because the sound quality was horrible. The music sounded grainy and definitely not worth $150. We had an older version of this speaker which sounded great, but unfortunately, this model was a let down.
Thanks for taking the time to share your experience. We're sorry to hear this speaker didn’t meet your expectations, especially after having a great experience with an earlier version. Your feedback is important and helps us understand where improvements can be made. We truly appreciate your honesty.

Extremely disappointed! Both the Miniroll and the WonderBoom sound far superior at a much less expensive entry point. I don't understand why the boom sounds so muffled???
