Sennheiser HD 550 Over-Ear Open-Back Headphones

Enjoy audiophile-grade sound and premium comfort with the Sennheiser HD 550, an open-back, over-ear headphone built for both high-fidelity music listening and immersive gaming. With a sleek, lightweight design and precise acoustic performance, the HD 550 delivers a refined sound signature and superior comfort that make it ideal for extended sessions at home or in the studio.

At just 8.3 oz, the HD 550 is designed to disappear on your head, offering a barely-there feel while delivering rich, transparent audio. The open-back design enhances both soundstage and breathability, offering a natural and spacious listening experience that sets it apart from closed-back alternatives.

Balanced Sound with Extended Frequency Response

Crafted for audio enthusiasts, the HD 550 features a wide 6 Hz to 39.5 kHz frequency range, reproducing every detail from deep lows to airy highs with clarity and control.

The combination of a laminate Duofoil diaphragm and a lightweight voice coil reduces unwanted resonances, resulting in a tight bass response, neutral midrange, and smooth, open treble. Whether you're gaming, streaming, or mixing audio, the HD 550 delivers a clear, balanced sound profile that brings out the full character of your music and content.

The 150-ohm impedance makes the headphones compatible with a wide range of playback devices, including headphone amplifiers, gaming DACs, and professional audio gear.

Immersive Open-Back Soundstage

With an open-back mesh housing, the HD 550 avoids sound reflections, creating a natural, wide soundstage that lets audio breathe. This design, combined with acoustic foam and an acoustically transparent dust cover, ensures precise treble response and a more lifelike presentation of voices and instruments.

You'll experience accurate imaging and depth, making these headphones ideal for spatial audio, music production, or hearing every detail in your game environment.

Comfortable Fit for Long Listening Sessions

Engineered for lasting comfort, the HD 550 includes a synthetic leather headband with reduced clamping force and soft velour ear pads that stay breathable over time. The lightweight construction and ergonomic fit help minimize fatigue, even during hours of continuous listening or gaming.

The open-back structure also adds airflow, so your ears stay cool without compromising on sound quality.

Durable Construction with Detachable Cable

Built on the proven HD 500 series platform, the HD 550 features high-grade components, including a robust metal mesh headband and a detachable cable system. The balanced input jack on the earcup allows for optional use with balanced headphone amplifiers or microphone-equipped cables, letting you easily convert it into a high-performance gaming headset.
