Sennheiser HD 559 Open-Back Headphones

Sennheiser HD 559 Open-Back Headphones

The Sennheiser HD 559 Open-Back Headphones are open-back over-ear headphones for relaxed, spacious listening at home. Unlike closed headphones, their open earcups let air and sound move freely, which gives music a wide, natural soundstage that feels more like listening to speakers in a room than having sound pressed against the ears. The result is an easy, non-fatiguing listen for albums, films and long evening sessions, with soft velour-style cushions that stay comfortable over time.

Why Choose Sennheiser HD 559 Open-Back Headphones?

Home listeners choose the Sennheiser HD 559 Open-Back Headphones because openness changes how music feels. Instruments have room to breathe, vocals sit naturally in the mix, and the 14 Hz to 26 kHz response reaches from deep bass to airy highs. The 50 ohm impedance keeps them usable with a wide range of sources, from a laptop or phone to a hi-fi headphone output, and the long 3 m cable means you can sit back from the system rather than perching beside it. For quiet-room listening, few designs at this price are as relaxing. The generous earcups spread pressure evenly around the ear rather than concentrating it on one point, and the headband distributes weight so the headphones stay comfortable through a full album or film without needing adjustment.

Key Features

• Open-back design: open earcups that create a wide, natural, speaker-like soundstage.

Best Suited For

The Sennheiser HD 559 Open-Back Headphones suit home listeners, music lovers and film watchers who listen in a quiet room and value spacious, natural sound. They are a good fit for evening albums, classical and acoustic music, and relaxed television watching. They are not the right choice for commuting, offices or shared rooms, because open-back headphones let sound leak out and let room noise in, and they have no microphone for calls.

Setup and Connection Guide

Connect the cable to a phone, laptop, hi-fi amplifier or television headphone output, using a 3.5 mm to 6.3 mm adapter if the socket is the larger size. Adjust the headband so the cushions sit fully around the ears, then set the volume low and raise it gradually. Because the design is open, choose a quiet room for the best experience and expect people nearby to hear faint sound leakage at higher volumes. These headphones are for listening only, so calls will use the connected device’s own microphone unless a separate microphone is added.

Do they need a headphone amplifier?

No. At 50 ohms they work with phones, laptops and hi-fi outputs, though a good amplifier can still add control.

Do they have a microphone?
