Open-back circumaural headphones that represent the essential tool for the most demanding professionals and have only one objective: to be the ultimate choice for high quality playback. They use a new generation of Focal 40 mm full-range speaker with 25mm diameter, 5.5mm long unsupported copper coil that has the effect of achieving an extremely high magnetic field in the coil. With this, the moving parts are always under control, even at maximum capacity, providing bass definition worthy of the best subwoofers. Its 55 Ohm impedance makes the headphones easy to drive, even in a mobile configuration, directly connected to the headphones output of a laptop. Thus the headphones are capable of precisely revealing the finest details of the recording, proving extremely precise control. The speakers also feature the M-profile dome formed from an aluminium/magnesium alloy, combining low mass, high rigidity and excellent damping. The headphones further feature microfiber ear cushions with 1mm diameter micro-perforations on the outside edge that provide a unique level of openness which leads to an intensified listening experience in the room. The second benefit to this design is its extreme tolerance to ear cushion positioning, regardless of head profile and size, plus it also improves definition of upper bass and low midrange registers. The headphones come supplied with a rigid carrying case with thermoformed shell in the shape of headphones, two OFC copper 24AWG cables with a very low resistance, a 5m spiral for domestic use, a 1.2m cable fitted with a 3.5mm stereo jack connector and 3.5mm and 6.35mm jack adapter.
