The special shape and luxurious materials of the SHS3701 earclip headphones ensure a perfect fit for maximum comfort. They prevent audio leakage as well as enhance bass performance. The ear cushions are shaped in such a way that they perfectly align with the area around the ear. The 27mm speaker driver is compact for wearing comfort yet big enough to deliver crisp, powerful sound – for non-distorted listening enjoyment. The contoured earhook design stays put behind the ear even when you’re on the move, keeping the earphones comfortably in place. The asymmetric cabling system works effectively by enabling you to hang the 1.2 meter cable behind the neck instead of under the chin.
