Pocket-Sized Wireless Speaker

The Diamond Mini Rocker is a portable Bluetooth speaker built for phones, tablets, MP3 players and laptops. It fits in a pocket and streams audio wirelessly from any Bluetooth source. A 3.5 mm cable is also included for wired devices.

Wireless and Wired Flexibility

Bluetooth streaming removes the need for a cable when you want to move around. The supplied 3.5 mm audio cable lets you plug in older players or conserve battery. No extra cords or adapters are required.

8 to 10 Hours Per Charge

One charge delivers between 8 and 10 hours of continuous playback. That runtime decides whether the speaker lasts through a full workday or a long journey without recharging.
