Play your music free and clear with the Pioneer C1s. These compact earphones are made for fun sound on the go. Large dynamic drivers love 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, and for the earphone tips to insulate against noise. You’ll be surprised how great they sound, and also at their high-value features. 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.
