This driver provides high response speed, reproducing clear sound over a wide frequency range from 6 Hz to 39,500 Hz, with total harmonic distortion below 0.2%.

With an impedance of 150 ohms, the HD 550 can be easily matched with a wide range of Hi-Fi audio equipment, and can also perform exceptionally well when paired with high-end equipment - such as Sennheiser's own HDV 820. The impedance of 150 ohms makes the HD 550 compatible with a wide range of Hi-Fi equipment, and can perform best when paired with high-end equipment such as Sennheiser's HDV 820.

The completely open-back design with a new acoustic metal mesh protects the driver while ensuring unobstructed sound. The driver is angled, creating an open soundstage that feels like you’re at the center of the recording. For gamers, this provides clear, smooth spatial orientation, serving both competitive gaming and relaxing entertainment. The HD 550 retains Sennheiser’s neutral sound philosophy, with powerful bass, natural, lively midrange and clear treble details.
