Reward: Ultimate Ears BOOM 3 Wireless Bluetooth Waterproof Portable Speaker

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.

You can connect over 150 BOOM and MEGABOOM speakers to create a wall of sound.

It’s been designed to survive pretty much anything – multiple drops, water, dust, and more. It can stay in water for up to 30 minutes.

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.
