Authorised Sennheiser Complementary Partner LogoThe Sennheiser HD650 is a dynamic, open-backed headphone model that combines a streamlined design with a richly-detailed sound reproduction in order to set a new standard in sound quality and listening enjoyment. Sennheiser’s unwillingness to compromise is reflected in the HD650’s frequency response, which goes from an ultra-low 10Hz up to an impressive 41kHz, and the drivers are hand-paired according to detailed measurement values in order to provide the most exact match between the left and right channels, thus enhancing the sound quality even further and delivering a particularly homogeneous response.

Easy to service and a solid investment

The Sennheiser HD650 headphones are designed to allow components to be replaced when required, so users can be sure that they have invested in a set of headphones that will be with them for a long time. The 42mm transducer features a 38mm diaphragm with an aluminium voice coil that allows a broad and natural-sounding frequency response with less than 0.05% non-linear distortion. With a maximum SPL of 103dB and an impedance rating of 300 ohms, the Sennheiser HD 650 is admittedly not one of the loudest models available, so a headphone preamp will be required in operation. The detachable cable is made from highly conductive OFC copper and optimally matched to the headphones to provide the best impedance, while its 3m length gives the user enough freedom of movement both in the studio and in the home recording environment. And the scope of delivery additionally includes a 20cm adapter cable with a 3.5mm mini-jack connector for those who want to use the Sennheiser HD 650 in combination with smart devices.

For studio users and hi-fi aficionados

Thanks to its expertly balanced acoustics, the Sennheiser HD650 reproduces the subtle details in the music that many other headphone models in the audio production sector leave undiscovered, which makes the HD650 an ideal tool for professional studio operators. Audiophiles on the other hand can look forward to both a high-resolution sound and a well-balanced frequency response that does not excessively boost the treble frequency range. The open-backed design of the Sennheiser HD 650 also allows the sound to “breathe” properly, while the low-resonance construction of the earcups in turn allows the sound waves to expand in a correspondingly natural manner.
