The JVC HA-F160 Gumy Earbuds from JVC feature a bass-boosting design for a frequency range of 15 Hz to 20 kHz (which, it's worth noting, encompasses the full spectrum of human hearing). The 13.5mm Neodymium driver unit ensures a powerful sound, while 3.3 ft of cord length afford you more than enough room to place a listening device in your pocket or on an armband.
