Sennheiser HD 559 Headphones

The HD 559 is part of Sennheiser's HD 500 series, which is focused on delivering excellent, pro-level audio that's accessible to all listeners. The 559 embodies this with solid sonic performance-thanks in large part to Sennheiser's Ergonomic acoustic refinement (E.A.R.) design and proprietary drivers. Measuring 38 millimeters across, the drivers contribute to the HD 559's easy-to-drive 50-ohm impedance levels. They're also capable of providing plenty of detail, with adequate low-end support, plus a wide frequency response range of 14 hertz to 26 kilohertz. The open-back construction also gives you the feel and presence of an in-room stereo system in the form factor of on-ear headphones. And, because the 559s use Sennheier's classic plush pads and headband in a uniquely contoured design, they'll fit like a glove.
