The new Wonderboom 2 ($100) from Ultimate Ears is a killer little Bluetooth speaker that packs a lot of punch for its tiny size. It sounds great, lasts forever, and is probably bombproof. It’s a winner all around.

Excellent size, Waterproof and robust, Battery lasts forever, Great sound for its size

Charges over microUSB instead of USB-C

Finally, if we had to characterize the Wonderboom 2, I would say that it is the ideal pocket-sized best friend for this summer!

Waterproofing, Battery life, Outdoor mode, Small size

Incompatible with other Ultimate Ears models, No USB Type-C, No headphone jack, Latency

As long as the price isn't too high for you, there's almost nothing to dislike about the Wonderboom 2. Ultimate Ears has taken its pocket rocket and made it even better with a more useful design, longer battery life and an Outdoor Boost mode. You might only be annoyed at the lack of an aux input.

WonderBoom 2 is a welcome upgrade to the WonderBoom with its increased sound profile, Double Up feature and revised styling. Only gripe maybe is you can’t do the Double Up stereo pairing with your older models if you have.

The Ultimate Ears Wonderboom 2 is an amazing Bluetooth speaker that is portable, packs in impressive sound and it floats so it’s your perfect pool companion. If you love to take your music to the beach, pool, shower or just where you’ll get muddy, the Wonderboom 2 can handle it all thanks to an IP67...

A couple years back, Ultimate Ears released the Wonderboom , a squat little speaker that delivered great sound at a good price. With some attractive color pairings, and big, easy-to-use controls, there was a lot to like about the speaker, though there was also clearly still room to grow.

Design The original Wonderboom was already a well-constructed, attractive speaker, and this new model only further refines that successful design., Audio quality Decently loud, clean, and an improvement from the original — if only it still sounded good when floating.

Outdoor Boost Underwhelming in our tests, it's possible this may deliver benefits in specific circumstances. Luckily the speaker's plenty loud already., Pricing For as great as the Wonderboom 2 is, $100 is a little bit on the steep side. Be on the lookout for sales.

The Wonderboom 2 is a great little speaker that's perfect for both indoor and outdoor use. It's super portable, puts out impressive sound, and it's not too expensive at $100.

Its compact size, 100 percent passable sound, battery life and waterproofing has made it the perfect speaker for me -- and likely you as well depending on what you're looking for from a portable speaker.

Compact size, Good battery life, Cute design

No companion app, Lacks fast charging, box doesn't include charging brick

Some few years ago, Ultimate Ears gave us the Wonderboom – a little speaker that provided us with excellent sounds at an attractive price. With some great colors and easy to manage controls, there were a ton of reasons to love the speakers.
