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.
