It’s added muscle for compact earphones. A big beating heart pumping bass under glossy mids and acid sharp details. With two speakers in each ear, every note and every layer sing out like you’ve never heard. 2-Way Noise Isolation means your music stays in your ears and the world stays out. And an inline stainless steel remote and mic deliver total volume and playback control. Made in metal. Meant for music. Must be worn to be believed.
