FiiO JD1 In-Ear Earphones Black

JD1 adopts 10mm diameter dual- cavity magnetic high-performance dynamic driver, and the whole LCP (Liquid Crystal Polymer) liquid crystal diaphragm to bring excellent transient response and high-resolution sound details. Asymmetrical internal and external magnetic circuits: Compared to the traditional design of a single internal magnet or a single external magnet, the asymmetrical internal and external magnetic circuits design effectively increases magnetic field density around the voice coil - leading to a more powerful and robust sound as well as improved transient response. Front-rear cavity balanced pressure relief:The JD1 is equipped with front-rear cavity balanced pressure relief technology, which not only allows the dynamic driver to move more freely for better bass but also reduces pressure on your eardrum for more comfortable listening. Lightweight at only 7g per unit: The JD1 is lightweight at only 7g per ear unit. This allows it to almost disappear in your ears for comfortable long listening sessions. Included cable comes with HD microphone with in-line controls - middle button used for answer/hangup and play/pause; top and bottom buttons used to adjust volume.
