Designed like the classic 80s boom box but made for the 21st century, Thumbs Up's Swipe Boombox Touch Speaker amplifies the sound on your mobile device and gives your bass a big boost. Place your phone or device on top of the speaker and the sound will instantly amplify – no wires or pairing needed. Compatible with most smartphones with external speakers, it uses wireless technology to produce a big sound. The built in rechargeable battery lasts ten hours, so you can take it with you if you're travelling or using it outdoors. The Boombox has a 3.5mm jack port to connect to a variety of devices without external speakers.
