The headphones that were released in Germany at the weekend have a built in a rotary dial that lets users customise the amount of bass they want.
The HD 630VB is being is billed as the company’s first closed audiophile headphone.
The majority of the headband and ear cups is made of tempered aluminium, making them lightweight and durable. The headband is collapsible and the headphones can be tidied into the case provided for easy storage and transport. The ear cups have detachable pads, and the one on the right has buttons to adjust volume, switch tracks and answer calls. The built-in mic means you can call hands-free via your phone.
The stand-out function here is that the transducers have been specially designed to allow you to adjust the bass (for +/- 5 dB at 50 Hz) to suit your taste. Connection comes in the form of a 3.5mm mini-jack cable, with a 6.35mm adapter also provided.
The HD 630VB’s frequency response ranges from 10 Hz to 42 kHz and harmonic distortion is less than 0.08% (1 kHz, 100 dB) with low impedance, at 23 ohms. Sennheiser has also advertised a Sound Pressure Level (SPL) of 114 dB (1 kHz/1 Vrm) and a frequency response for the omnidirectional microphone between 100 Hz and 10 kHz.
