Best Sennheiser HD 630VB Black Friday and Cyber Monday Deals & Sales 2021:

The HD 630VB headphones were designed for audiophiles who want to leave the house “while keeping their headphones high fidelity” . Its special feature is its ability to adjust the bass using an integrated dial. As usual, Sennheiser announces headphones with a worked and very faithful audio rendering. We will therefore see how he manages his dual identity as a nomad and a domestic audiophile.

Ergonomics

With its 400 grams and its 9 cm diameter over-ear headsets, the Sennheiser HD 630VB is not minimalism. Fortunately, the helmet is foldable thanks to a priori ultra-robust aluminum hinges , just like the slides, the headband and the ear cups – appreciable for outdoor use. Even when folded, the HD 630VB takes up a lot of space in its huge hard case

The helmet has removable thick memory foam ear pads. Comfortable, of course, they tend to keep your ears warm. However, the foam under the arch is not very comfortable. Indeed, we feel a very strong support on the top of the skull, a real negative point for domestic use

Another downside, its 1.2 m cable (standard length for nomadic use) is too short for traditional hi-fi use. Not removable, it is also often subject to the risk of rupture. Details that seem to us to be obvious

The settings (volume, change of audio track, pause / play or bass adjustment) are directly available via the buttons on the right headset. Failing to change the cable, a button (see photo above) allows you to switch from iOS compatibility to that of Android – an innovative system that we had never seen on other products. 

Audio

The manufacturer announces a frequency response ranging from 10 to 42,000 Hz, a sound pressure level of 114 dB SPL at 1 kHz for a distortion less than 0.08%. According to the manufacturer, the Bass Boost system allows you to adjust +/- 5 dB in the bass – more precisely at 50 Hz

The HD 630VB offers a relatively faithful frequency response across the entire audible spectrum. There is a small bump in the lower mids generating a sound with a fairly warm coloring. The voices are very intelligible and slightly highlighted, which is reflected above by the bump that we see between 1 and 2 kHz. Note that no sibilance comes to attack our eardrums; the clicks are soft and the overall result is not very shiny.

As we can see on the curve above, the calibration is pretty well done, with a gradual rise in the bass around 50-60 Hz. This trick thus allows to offer more or less present bass (+ / -4 dB on our measurements against the promised 5 dB). The latter are well controlled and rather reactive, accompanied by controlled distortion. A successful bet for the German manufacturer.

The very low harmonic distortion rate is therefore inaudible across the spectrum. The curve above represents the distortion at its maximum in the bass (Bass set to maximum), far below the threshold of 1%. The stereophonic scene is acceptable for a portable headset, but does not deploy as broadly as with a traditional hi-fi headset – a feature difficult to adjust with a closed design.

CONCLUSION

The Sennheiser HD 630VB is certainly rather versatile, but this is not always to its advantage. Thus, we wear an imposing helmet, quite heavy, not always comfortable, with a non-removable cable, but too short for domestic use. On the audio side, fortunately, the performances are very good thanks in particular to the adjustable bass and the faithful rendering.
