The Boombot Pro Speaker boasts the best audio performance out of any speaker in the Boombotix lineup. It's also the only Bluetooth compatible speaker with 2GB of flash memory so you don't have to use your smartphone to keep tunes a'blazin'. Dual coil acoustic drivers with progressive DSP tuning ensure astounding sound. Boombotix paired this intense audio with a rugged, waterproof case made of alloy and rubber. This compact and lightweight speaker also features a clip for shoulder straps, a rechargeable battery, and hands free voice control for answering calls, changing tracks, and playing music until the sun sets.
