These in-ear headphones with twin vents give a more balanced, natural sound for more enjoyment with music on the move. 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. Specially designed vents that channel the air balance the high tones and bass for a more rounded listening experience. Small enough for optimum wearing comfort and big enough to deliver crisp, non-distorted sound, the 15 mm speaker driver is an ideal size for listening enjoyment. 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. The soft, flexible part protects the cable connection from damage that otherwise would occur due to repeated bending.
