The UE Wonderboom might just be the cutest little UE wireless speaker yet, with the plump lines of an anime character or a bulldog puppy. There’s more than just style to this little guy, though, with great water resistance and a flexible cord letting you stash it almost anywhere. Sure, there are speakers for the same money that sound a little better, and it’s those that you should go for if audio quality is all that matters, but the Wonderboom’s flexibility and bassy loudness largely makes up for any slight sonic shortcomings. That’s right; this is another belter of a Bluetooth speaker from UE. Buy the UE Wonderboom here from Amazon

Loud, with decent bass kick for the size; Cute; impressive water resistance;

Mids are a bit thin/cold, which means vocals aren't as good as they might be;

Update, June 4, 2019: Ultimate Ears has announced a sequel to this product. The UE Wonderboom 2 is slightly larger, adds longer battery life and offers stereo pairing.

For its size, the affordable and durable UE Wonderboom is one of the fullest sounding mini Bluetooth speakers you can buy.

The Wonderboom is compact, fully waterproof, plays very loud for its size with a good amount of bass for its small size; It also floats in water, is shock resistant and has decent battery life; You can pair two Wonderbooms together to augment the sound.

No speakerphone capabilities; It's slightly too bulky for travel use.

It's difficult to get a lot of power out of a small speaker: You generally need more physical volume to produce more audio volume. Ultimate Ears pushes those limits with the UE Wonderboom, a tiny Bluetooth speaker that delivers a sound loud enough to fill a room. The Wonderboom doesn't produce the cleanest highs or distortion-free deep lows, but it's portable, rugged, and fairly priced at $99.99. The JBL Charge 3 ($95.99 at Amazon) delivers a bit more audio finesse in a larger package, but the Wonderboom is a solid alternative. Design The Wonderboom ($68.00 at Amazon) is a squat, rounded cylinder shaped vaguely like a Japanese lantern. It's available in six different colors, including black, blue, gray, orange, pink, and purple. It measures 3.6 inches around, 4.0 inches high, and weighs 15.2 ounces, making it too large to slip in a jacket pocket, but a fine size for a bag. A small, thick elastic loop on the top lets you easily clip the speaker to your bag or hang it from a hook...
