Woojer Strap 4

STRAP 4 amplifies music, games, movies, and VR, letting you feel the sound. It's like the energy of a live concert pulsating through your body, delivering something headphones alone simply can't.

STRAP 4 is a high-quality, touch-sensitive body strap that lets you experience the thrill of gaming, listening to music, and watching movies. STRAP 4 was created to accompany you on the go, so you can feel the intensity of sound wherever you are. Wear it on your hips, across your chest, or slung over your shoulder.

The new Series 4 product line comes with a new, dedicated app that lets you control the appearance of your Woojer device, manage its basic functions, control audio settings, and update its software.
