The Sennheiser HD 550 features a custom 38mm transducer for exceptional clarity and a wide frequency range (6 Hz to 39.5 kHz) with low distortion, housed in an open-back design that delivers an expansive soundstage ideal for both audiophiles and gamers. Its lightweight build, soft headband, and modular design ensure long-term comfort and versatility, with compatibility for various audio setups.

HD 550

The new HD 550 brings a compelling new choice to audiophiles and gamers seeking next-level capability that outshines its price tag.

A Deeper Audiophile Experience
The heart of the HD 550 is its custom 38mm transducer, made at Sennheiser’s audiophile production facility in Tullamore, Ireland. Its speedy performance yields exceptional clarity from 6 Hz to 39.5 kHz, all while producing less than 0.2% total harmonic distortion. At 150 ohms, it’s an ideal match for a wide variety of hi-fi gear, scaling with ease when paired with premium audio gear such as Sennheiser’s own HDV 820.

The fully open-back design utilizes a new acoustic mesh that protects the transducers while removing any remaining barriers between the listener and their music. Their angled arrangement creates an expansive soundstage that drops the listener into the epicenter of the recording. Gamers will experience superb, lag-free spatial awareness and immersion for both competitive and casual sessions. True to the Sennheiser brand’s heritage, the HD 550 delivers punchy bass, crystal-clear transients, and neutral mids without straying from the truthful voicing that audiophiles prefer.

Built for Comfort
Situated in chassis renowned for its long-term comfort, the HD 550 features a more relaxed clamping force compared to other 500-series stablemates. Weighing less than the most popular gaming controllers at a mere 237 grams [8.4 oz], the HD 550 practically disappears on the head. A soft-touch textured headband and ventilated metal mesh earcup covers keep the listener comfortable without sacrificing durability.

Like other models in the 500 series, the HD 550 features a modular design, allowing for easy swapping of cables and earpads. It ships with a 1.8 m cable terminating with a stereo 3.5 mm jack plug with a 6.35 mm adapter, making it compatible with a wide range of devices. A range of additional cables—sold separately—makes it easy for listeners to adapt to balanced sources and mic-enabled jacks, for example.
