Great sound out of a tiny speaker. This little portable speaker packs a huge punch for its size. Sound quality is always great from UE.

[Employee of bestbuy] Ought this as a small portable shop speaker, probably the best speaker I’ve owned for the price. Battery cranked out last for hours

Great Travel Speaker
Kadydd Posted
Bought this little speaker as a an item to travel with. It’s small and takes up little room in my carryon. Battery life is great and it really is waterproof and floats. Sound is crisp and clear. I do wish the bass was a little better, it’s weak compared to the larger models. I normally wouldn’t expect much out of a speaker this small however, the I don’t know that it earns the “Boom” in its title.

This little speaker really puts out high quality sound. It's great for indoor and outdoor gatherings. If you get 2 of these, they can be paired to work in stereo. Great speaker!

Small speaker, perfect sound
Realfeel105 Posted
I love the UE Wonderboom. Its small and the sound is great. Battery lasts longer than expected and its easy to pair up with iphone as well. Of course, before buying you need to establish what your main use will be. It’s awesome for the patio or garage, or to use while cooking. It might not be the go to speaker for a party, though. For the price, its tough to beat.

Great bluetooth speakers!
Lane Posted
Really cute bluetooth speakers. I got the pink and blue one for the stereo effect. The sound is awesome and they are very convenient, especially when wanting to listen to the program in different rooms. So far, the range and battery life seems to be good. The only reason I rated them 4 instead of 5 is because sometimes they are hard to connect to my Roku player. I have to make the attempt a couple of times in order for them to connect. Of course, that may have to do with my learning curve as I just recently purchased and started using them. Overall, they are great!
