Design headphones "behind the ears" with a 10 mm dynamic transducer, closed construction and a durable exchangeable cable in the length of 1.25 m. The cable has a remote control with a microphone and controls for receiving calls or switching songs. The impedance of the headphones is 24 Ohm and their sensitivity is 112 dB / mW. You connect them to a phone or other player using a curved 3.5 mm jack connector. The headphones have an ergonomic design, so they fit snugly in your ear and the silicone attachments ensure that they will hold great.
