Design headphones "behind the ears" with a 10 mm dynamic driver, a closed construction and a durable replaceable cable 1.25 m long. The cable has a controller with a microphone and controls for receiving calls or switching tracks. The impedance of the headphones is 24 Ohm and their sensitivity is 112 dB/mW. You connect them to your phone or other player using the bent 3.5 mm jack connector. The headphones have an ergonomic design, so they fit perfectly in the ear, and the silicone tips ensure that they hold well.
