Is the Wonderboom 4 waterproof?

Yes. It has an IP67 rating for dust and water and it floats, so it survives pools, rain and beach trips.

How long does the battery last?

Up to about 14 hours per charge, depending on volume. It charges over USB-C.

Can I pair two Wonderboom 4 speakers?

Yes. Two units can be paired for stereo sound using the Outdoor Boost and stereo pairing controls.

Does it have a microphone for calls?

No. The Wonderboom 4 has no speakerphone, so it is for music playback only.

How does it compare with the Wonderboom 3?

The 4 keeps the same rugged floating design and adds USB-C charging and updated sound tuning. The differences are modest, so owners of the 3 have little reason to upgrade.

Our take on the Ultimate Ears Wonderboom 4 EXC

The Wonderboom 4 is Ultimate Ears' palm-sized portable Bluetooth speaker, built for outdoor use with a floating, drop-tested body and an IP67 dust and water rating. It plays loud for its size, pairs two units in stereo, and runs up to about 14 hours per charge. It suits people who want a rugged take-anywhere speaker more than room-filling home sound. Against the JBL Go and Clip lines it is tougher and fuller-sounding, but it lacks a speakerphone and an app equalizer.
