Review: These speakers are friggin awesome. Got one for each of my parents for their birthdays this year. The audio is crystal clear and it also gets very loud for its size without compromising the audio quality. Great for both music and podcasts etc. Also love that you can attach a carabineer to the speaker so you can hook it onto your pants or backpack etc and have the speaker effortlessly follow you around. The different settings/features are also really cool and handy. Would definitely recommend this product and honestly any product from the Ultimate Ears speaker line as in my personal opinion this line of speakers is the best line of portable speakers I know of or have ever heard. They're priced well too. I mean they aren't super cheap but they aren't overly expensive either, it's kinda right in that sweet spot. If you've got the money and you're looking for a portable speaker, look no further than this line because the sound quality and loudness (without distortion) you really won't find anywhere else especially for these prices. I know I'm starting to sound like a UE shill at this point lol but honestly I just really do love and admire their speakers and don't think they get the credit they deserve. Anyway hope this helps!

*by P***S on 12 January 2026*

Great little speaker with impressive sound for its size! The bass is solid, the audio is clear, and pairing with devices is quick and easy. I grabbed it at a Prime discount, which made it an even better deal. It’s compact, portable, and pairing it with another Wonderboom really boosts the volume and fills the house with sound. Easy 4/5 — highly recommend!
