Play your music free and clear with the Pioneer C1s. These compact earphones are made for clear sound on the go. Large dynamic drivers provide strong bass and have a clean mid-range for vocals. Drivers and nozzles are specially angled to send sound directly into your inner ears. This structure also helps the C1s stay in place. The thick, durable, tangle-resistant cable has a remote button to make, take, and end calls; there are six matching color schemes to choose from; and the earphones come with three sets of earphone tips for a comfortable fit.


Rich, high-quality sound from a compact body

The C1’s sensitive φ 9 mm (11/32˝) drivers increase audio resolution, deepen bass, and clarify high- and mid-range sound. Ear Direct Mount Structure aligns driver and nozzle directly into the inner ear for improved bass response, sound isolation, and fit.

Thick, durable cable with remote

The C1s feature a thick, tough, and durable φ 2 mm (3/32˝) cable that’s less prone to damage during life’s rough and tumble. It also resists tangling when stuffed in your pocket or bag. A simple inline remote with mic lets you make and take calls easily hands-free.
