Unrestricted mobility and an innovative powerhouse in your luggage: the ROCKSTER CROSS provides the perfect wireless music experience wherever you go, with CD-like sound quality thanks to Bluetooth® aptX™. This speaker offers an impressive, ultra-compact design, smart features and remarkable sound. With synchronous playback after linking two speakers and controlling two different smartphones, the CROSS now adds even more variety to music streaming.

Portable power that lasts all day long

The powerful lithium-ion battery (5,800mAh) guarantees up to 16 hours of uninterrupted listening pleasure from morning to evening. A handy carrying strap keeps the speaker in place even when you're moving around a lot, so you can be sure you'll always have appropriate sound to motivate you at any given time. A special outdoor mode guarantees intensive music playback in any location. The Bluetooth® speaker also has an IPX5 enclosure and is shockproof and water jet-proof thanks to its flexible, thick-walled housing.
