Sennheiser HD550
Sennheiser HD550
The Sennheiser HD 550 are wired headphones with an open-back design and 38mm dynamic drivers. They offer a frequency range of 6Hz to 39.5kHz, an impedance of 150 Ohm, and drivers positioned at an angle within the earcups to create a natural and open soundstage. Their sound tuning combines strong bass, natural mids and an extended high-frequency response. Weighing 237g, their design is engineered for comfort during long listening sessions. The soft padding on the headband, the over-ear earcups and the low clamping force are complemented by a durable metal grille on the earcups.

Open sound with 38mm drivers
The Sennheiser HD 550 use 38mm dynamic drivers with an impedance of 150 Ohm. The drivers are angled within the earcups to support a spatial sound delivery. The frequency range is from 6Hz to 39.5kHz, and the resulting tuning focuses on balanced and clear reproduction. The sound performance offers strong bass, natural mid-range frequencies and an extended high-frequency response. The open-back construction contributes to the airy character of the reproduction and a natural perception of the soundstage.
Lightweight design for long listening sessions
The Sennheiser HD 550 headphones weigh 237g, and their construction is adapted for long and frequent listening sessions. The headband and earcups are designed to gently cup the head and distribute pressure evenly. The modified headband contains less plastic, features soft padding and is covered with synthetic leather. The earcup construction is complemented by a high-quality metal grille corresponding to the open acoustic design.
Wired connection and replaceable accessories
The headphones use a detachable, single-sided 1.8m cable terminated with a 3.5mm stereo jack. The package includes a screw-on adapter that allows connection via a 6.3mm jack. The wired design ensures sound transmission without the need to power or charge the headphones. The design allows for the replacement of accessories and is compatible with all accessories from the HD 500 series. The package also includes a fabric pouch for storing the headphones and documentation.

Impedance
This figure indicates how much power the headphones require. Headphones with a lower impedance (e.g. 32Ω) are ideal for mobiles and laptops. A higher impedance (e.g. 80Ω and above) is more suitable for Hi-Fi players and amplifiers.
Frequency Range
Indicates what sounds the headphones can reproduce. The typical range is 20Hz–20kHz, which corresponds to what the human ear can hear. Lower Hz = deeper bass, higher kHz = more detailed treble.Specifications
