The FiiO JD7 earphones reproduce your music vividly and powerfully. The 10 mm dynamic driver provides a propulsive sound with beautifully rich bass. The steel housing gives the JD7 a cool industrial design look and makes it robust and durable. The semi-open design with the three grooves on the top of the earphones reduces pressure on the eardrum, so you can enjoy your music without fatigue and without damaging your hearing, even during long listening sessions. In addition, the semi-open design creates a particularly natural sound with a wide soundstage. With a sensitivity of 108 dB, the JD7 delivers top sound with any music source and also delivers enough punch when used with smartphones. The 1.2 metre long earphone cable made of monocrystalline silver-plated copper has a 3.5 mm plug for connection to a playback device as well as MMCX connections on earpieces and can be replaced if necessary. The cable is routed over the ear. This way, the earphones sit firmly in the ear cup and the weight of the cable does not pull down on the two earpieces. Three different types of earplugs in different sizes, shapes and sound signatures are included in the delivery. So you can find the right set for every ear canal and sound taste. A robust waterproof hard case is also included with the JD7 so that the earphones with all accessories can be safely stored and transported.
