Our experts have some serious techsperience, and they think you'll love this Ultimate Ears BOOM 3 Portable Bluetooth SpeakerThe 360-degree speaker projects music into every corner of the room, while the rock-solid, waterproof casing has passed more than 25 durability tests - no need to worry about drops.

Load and clear

The Ultimate Ears BOOM 3 Portable Bluetooth Speaker pumps out sound in every direction, so you can place it in the centre and everyone will hear every note. It has a deep bass for a portable speaker, so you can enjoy a thumping dance track anywhere.

Boost the volume by pairing up with other speakers. You can connect over 150 BOOM and MEGABOOM speakers to create a wall of sound.

Control the music

Simply touch the Magic Button on the top to play, pause, and skip tracks. Anyone can control the music without having to use the Bluetooth-connected smartphone, so you can send some messages or tweets without interrupting the party.

Tough design

The BOOM 3 is no ordinary speaker, it's been designed to survive pretty much anything - multiple drops, water, dust, and more. Take it to the pool party and watch it float - it can stay in water for up to 30 minutes.

Charge it up

With a battery life of up to 15 hours you won't have to charge often, but when you do the charging dock (sold separately) will come in handy. Leave it on the dock and it'll be ready to grab and go for your next outing.
