Customer Ratings & Reviews

This speaker has to be the best speaker I have ever heard. It’s small but powerful in sound and can be heard from a mile away!

I bought this to play music during my back yard get togethers. It has a great sound and I use it while playing golf. Has a really rich sound.

We purchased 2 and love them, one was for a gift and the sound is just amazing from this little guy, the process was right too.

I really enjoy using my new speaker. I use it outside and inside. The volume can get fairly loud too.

I purchased two speakers as gifts for my teenage children for Christmas. They seem to love them. They can be heard through of the house:/

This little speaker gives big boy sounds. My son is happy with this speaker. The sounds are clear with good bass

This little speaker packs some punch. Got it on sale and have been using it a lot. Very durable and can withstand dirt and eater.

Ultimate Ears could always be relied on for loud and clear sound, and for the size of this unit, it is very impressive.

This speaker has amazing around quality... Only bought one; however, I see a few more of these being purchased soon

Good quality. Good sound. Kinda bulky. Wish they would make a quality slim one if they don’t already. Might buy another one.

The color is perfect and the sound is great! It fits my girlish personality to a T! I wish I could buy another.

This speaker can be combined with another wonderboom to make a party in the backyard into a music filled fiesta!!

I bought one for hubby and one for my son, they both were thrilled. I love it when that happens. Great sound!

Bought for outdoor use and it hasn’t diassappointed. Used while floating and swimming. Great sound in a little package.

I bought this for my daughter she absolutely loves it it’s perfect for sitting out on the patio or just relaxing at the house .

Sound has a great taste and louder than any other in its class without all the distortion at max volume !

The sound is perfect for a small gathering. My mom is going to like it a lot. Sound clear and crisp even in my car

i got this for my wife so she can listen to music in the shower, sometimes i have to tell her to turn it down

Few instructions included but online manual if you require assistance. Simple to pair to phone. Great sound and Bluetooth connectivity.

So like the title says, this would be a solid buy at $40, not anything close to being a good buy at the full $100. I needed something I could use in the bathroom when I’m getting ready in the morning, and had a generic waterproof speaker that I got for $15. Saw good reviews and decided to pick the wonderboom when it went on sale. I was honestly a little let down. It does get louder, but the sound didn’t sound notably better than the cheap generic one I had before, outside of more bass. So I’d say if you’re getting this as your first waterproof speaker and you can get it on sale, then it’s a fair buy. Otherwise I’d look elsewhere.
