A New World of Detail and Precision

Discover the details you’ve been missing and experience your favorite music, games, and media like never before with the Sennheiser HD 550. From the subtle breath of a vocalist to the distant echo of footsteps in a game, the HD 550 reveals the sonic layers hidden deep in every mix.

Deep sub-bass frequencies you can feel, not just hear, combine with treble that extends far beyond the limits of human hearing to create a sound that’s as lifelike as it is powerful. A wide, immersive soundstage drops you right into the center of the action. All of this comes in a lightweight, ultra-comfortable design that’s built for long listening sessions and designed to deliver high-end performance without high-end gear.

Acoustic Sorcery

Unlike many modern headphones that rely on digital trickery to shape their sound, the HD 550 keeps it pure with a direct analog signal path. No added processing, just clean, uncolored audio.

Built around Sennheiser’s in-house 150-ohm transducer, crafted in Ireland for precise channel matching and housed in the time-tested HD 500 series chassis, the HD 550 is engineered for uncompromised performance. The angled drivers recreate a natural, 3D soundstage, while an acoustically transparent dust cover, carefully chosen ear cushion materials, and a tuned foam insert work together to deliver smooth treble, tight bass, and a balanced, neutral tone.

Light and Comfortable

The HD 550 was designed with you in mind, shaped by real user feedback that called for lightweight comfort and uncompromising sound. Sennheiser reengineered the headband with premium synthetic leather and softer foam, reducing overall weight and eliminating the need for tight clamping.

That led to the use of plush velour earpads that feel soft and breathable, delivering a secure fit that practically disappears during long listening sessions. Whether you’re working, gaming, or just enjoying your favorite music, the HD 550 lets you listen for hours without discomfort, pressure, or the hassle of charging and pairing.
