Pioneer’s C4 wireless headphones offer a feast of features. Outdoors, commuting, or chilling out, they immerse you comfortably in a bass-rich world where vocals shine with pure vibrancy. You’re in control even when you can’t reach your phone with Pioneer Notification App for Android™, which reads out SMS and more hands-free. Control music playback, make and receive calls, or ask your phone assistant for help via simple remote attached to a durable φ 2.0 mm (3/32˝) cable. You can even pair two phones to your C4s at the same time.
