Honestly wonderbooms are the best! This is my third one in 3 different sizes. I love how they pair together, come in great funky colours and are easy to use. Great sound too!

Great little resilient speaker. I paired it with my Wonder-boom 2 which worked ok. It doesn’t give the full stereo separation of sound that I’d hoped for and you don’t get the same sound as a system with a subwoofer, but for this price point it’s a good product.

As the contented owner of the bigger Boom Ultimate Ears Speaker, I recently bought the Wonderboom for my son for Christmas. He is extremely pleased with it. He can have his phone on in the kitchen and the speaker outside near the pool and the sound is amazing. He hasn’t turned it up to full volume yet as he finds the volume and clarity is exceptional. He and his family are enjoying the Ultimate Wonderboom 4 and I’m so glad I chose the pink as it adds to the charm of this great little Bluetooth speaker.
