Sennheiser Launches HD 630VB Closed-Back Headphones
by audioXpress Staff
Sennheiser introduced its first closed audiophile headphone model at the High End 2015 show in Munich. The new Sennheiser HD 630VB are circumaural headphones, designed to deliver well balanced sound and offer a distraction-free listening experience, whether at home or on the move. A unique feature is a rotary bass dial, which allows increasing the bass response according to personal preferences.

“The HD 630VB is a milestone for Sennheiser: For the first time, we translated our long-standing experience in the field of high-end audio into a closed-back design. Featuring passive noise cancelling, the HD 630VB reliably insulates the user from ambient noise, so he can fully focus on his music”, says Axel Grell, Portfolio Manager Audiophile at Sennheiser.

Specifically developed for the HD 630VB, Sennheiser’s proprietary high-performance transducer is the “heart” of this model. It delivers the power for an intense bass experience which can be customised via a rotary bass dial according to the listening environment, the music being played and the user’s individual preferences. With total harmonic distortion of less than 0.08 percent (at 1 kHz and 100 dB sound pressure level) and thanks to a coil wire made from pure aluminium, the HD 630VB achieves an unaltered sound image with a precise reproduction of voices and instruments in the midranges and brilliant trebles.

With an impedance as low as 23 Ω, the HD 630VB is an ideal companion to portable music devices as well. Offering a frequency response of 10 to 42,000 HZ, the headphones are suitable for reproducing high-resolution audio files. Enjoyment of quality audio on the move is effortless thanks to a collapsible design that has been crafted from lightweight materials: Sennheiser used dampened aluminium on the ear cups, headband and sliders. “We chose these robust materials to ensure maximum durability”, said Axel Grell. “Additionally, we made sure the ear pads are exchangeable and easy to replace.”

Featuring a remote control on the right ear cup and a microphone which has been integrated into the high-quality OFC cable, users can comfortably control music and take calls on current smartphone models. The headband is easily adjustable while the soft ear pads give enhanced comfort even over long periods. “The HD 630VB impresses with both its exceptional sound performance and its minimalistic modern design”, says Axel Grell.

Sennheiser headphone’s history
Sennheiser has a long history in headphone design and manufacturing. Sennheiser’s HD 414, the world’s first open headphones revolutionised the market in 1968. For the first time, the ears could hear in a way that they are accustomed to: open and free in space. The sound could travel to the ear drum much more naturally and clearly than in the closed models which were available at that time. With its new principle, the HD 414 triggered an absolute boom in headphones sales. More than 100,000 sets of headphones had already been sold by the end of 1969. Until today, the HD 414 remains one of the best-selling headphone models in the world, with a total of over 10 million units sold.

A further milestone followed when Sennheiser engineers combined the principle of open headphones with that of electrostatic transducer technology for the first time. Sennheiser’s launch of the unipolar 2000 model in 1977 caused a sensation in the audio world. Its principle was once again an innovation in audio technology. In the electrostatic transducer, a high voltage is applied to two mesh-like electrodes. Just like in a loudspeaker, this voltage causes a coated foil diaphragm to vibrate in time with the audio signal. This results in an extremely fine resolution and low total harmonic distortion.

In 1991, Sennheiser launched the electrostatic Orpheus HE 90/HEV 90. With the boldly ambitious mission to build the best headphones in the world, Sennheiser developers exceeded all expectations with these electrostatic headphones and their impressive tube pre-amplifier. Two platinum-coated diaphragms vibrate between gold-coated glass electrodes. A 500 volt tube amplifier provides enough power to allow the Orpheus to fully unleash its sound. Due to the extremely complex technology involved, the Orpheus was produced in a limited edition of just 300 units. These legendary headphones still remain the ultimate benchmark for audiophile listening and for all high-end models which audio specialist Sennheiser continues to develop.

With the HD 800 dynamic headphones Sennheiser developed another classic. Its innovative ring design reduces distortion to a minimum even with a transducer as large as 56 mm, as the vibrating part of the diaphragm is not a circular surface area but only an annular section. Significantly less material thus results in less inertia and less additional vibration in high frequency ranges. The result: benefiting from total harmonic distortion of less than 0.02 percent (at 1 kHz and 100 dB sound pressure level), the HD 800 with its brilliant trebles and precise bass offers a sound image of unsurpassed clarity.

Other classics in the Sennheiser high-end world are the HD 600 and HD 650. Both models are open, dynamic, hi-fi stereo headphones with highly optimised transducer systems, using extremely light aluminium drive coils, while neodymium ferrous magnet systems guarantee maximum efficiency.

Sennheiser’s product range is rounded off by the headphone amplifiers HDVD 800 and HDVA 600. Both the digital HDVD 800 and the analogue HDVA 600 are high-end devices with a fully symmetrical layout for operation with analogue audio sources, thus ensuring absolutely symmetrical signal transmission from the source to the headphones.
The new Sennheiser HD 630VB model was undoubtedly one of the main attractions at the High End 2015 show in Munich. It was also one of the few headphones which could actually be evaluated in the noisy environment of a trade show due to its closed design.

Launching the HD 630VB at the High End show 2015 in Munich, Sennheiser now combines the best sound of open audiophile models with excellent passive ambient noise attenuation. The HD 630VB delivers an impressively spatial sound image, while allowing for the users to enjoy their listening experience without any distractions. The HD 630VB will be available through selected Sennheiser sales partners from June 2015. Sennheiser offers a two-year warranty on the headphones.
