These noise-canceling headphones use an external microphone to pick up background noise and then use sophisticated electronics to cancel it out. It is compatible with practically all smartphones, iOS, Android, Blackberry or Windows Phones. Clear, natural sound with active noise reduction (ANC) lets you enjoy a lifelike sound, blocking the noise around you so you can be immersed in the music or phone call.
