This waterproof Bluetooth speaker from Monster Products is ideal for the shower or pool. It’s the perfect Back-to-School gift for the college student who needs some loud music in the shower before that early morning class. The BackFloat has a built-in microphone with advanced noise cancellation for hands-free calling and conferencing. It comes with a rechargeable lithium-ion battery to provide up to 5 hours of music. The less than 10-inch wide footprint makes it ideal to take with you to the pool or beach (it comes with a carrying case). It’s no surprise that this speaker from Monster has tremendous sound quality with its no distortion high volume sound, two front full-range drivers for clarity and coherence and two bass radiators.
