The FT15 use 101mm planar drivers with an 800nm diamond-coated diaphragm for spacious, detailed sound with controlled bass. A 24-ohm impedance and 95dB/mW sensitivity make them easy to drive, and the 4.4mm balanced cable comes with 6.35mm and XLR adapters. At 425g they're heavy, the stock cable is short, and the open-back design is for home listening only.
