Big Sound, Small Package

The Ultimate Ears Wonderboom 4 is a compact bluetooth speaker you can fit in the palm of your hand, but don't let its size fool you -- this thing pumps out loud, clear 360° sound with satisfyingly thumpy bass and greats mids and highs. It's sturdy, waterproof, has a forgivingly long wireless range, and it even floats in water, making it perfect for any situation from camping trips to pool parties, or just casual listening. I like that Ultimate Ears chose a simplistic look with bold colors for these speakers, and the silicone base helps ensure that they stay put. My only gripe is that the Outdoor and Podcast EQs kind of sacrifice some clarity to push the volume in their respective directions, but the standard EQ is so rich and the speaker is so outspoken that either problem these modes attempt to solve are really non-issues, and the fact you can pair up two of these speakers for full two-channel stereo is a big plus. In addition, the regular sound signature is so clear that you can crank the volume with no noticeable distortion. I also wish you could skip back a track with the onboard controls, but doing it on your device isn't that much of a hassle. For this price range and size, I'd say the Wonderboom 4 should be your first choice for a portable bluetooth speaker.

Great little portable speaker

It's easy to pack around and has pretty good sound for such a little guy. Primary uses are music and audiobooks and the sound quality good enough that I'm satisfied. It's not Bose, but it sure ain't bad. I use it in the shop, out by the pool and when I'm gardening. Outdoors the sound travels a bit better if there is a wall or something solid behind the speaker. The loop makes it easy to carry or hang up and the 360⁰ sound means less fussing around with location and direction. Connected to my Android, playing on Spotify, I can crank it all the way up with no distortion or crackling. But, I only did that this one time, so I could note it in the review. It's pretty freaking loud. It's solid with a rubber cap on both the top and bottom. In case of a drop, those could be lifesavers. I've never tossed it in the water, so cannot attest to it's water resistance. It connects quickly and easily to any Bluetooth device and the buttons on top provide easy access to pairing, pause and power. It will power down if left unused for a few minutes to preserve the battery. That's a nice function. I'm not wild about the HUGE volume controls on the front. I think they're ugly and detract greatly from the overall appearance of the speaker. Overall, good value for the money.

Audio Perfection

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!

This Speaker Is Possessed by a Much Larger, Angrier Speaker

The Ultimate Ears WONDERBOOM 4 is built like a friendly little bean and sounds like it does CrossFit and drinks black coffee for fun. I turned it on and my house said, “Oh. We’re doing this now.” The bass showed up uninvited and started rearranging the furniture emotionally. The 360-degree sound is real. I walked in a circle around it like an idiot and the music followed me like a curse. I put it in the shower. Loud. I put it by the pool. Louder. I dropped it in the pool. It floated. Still yelling. I walked away from my phone. Then I walked farther. Then I forgot where my phone was. Music never stopped. This speaker is loyal to a fault and clearly doesn’t respect personal space. Battery lasts forever. Pairing takes half a second. Survives water, dust, and my playlist decisions. Five stars. If this thing gets any louder it’s going to start paying rent.
