The SHE2637 in-ear headphones give you a perfectly balanced and natural sound. Specially designed vents that channel the air balance the high tones and bass give a more rounded listening experience. The special shape and luxurious materials used for the ear cushions ensure a perfect fit for maximum comfort. They prevent audio leakage and enhance bass performance too. The ear cushions are shaped in such a way that they perfectly align with the area around a person's ear. Neodymium magnet enhances bass performance and sensitivity. Neodymium is the best material for producing a strong magnetic field for greater sensitivity in a voice coil, better bass response and higher overall sound quality. A soft, flexible part protects the cable connection from damage that otherwise would occur due to repeated bending.
