Ergonomics

As promised, the HD 4.50BTNC does indeed opt for a minimalist design. The design, rather well done, goes straight to the point. The helmet rests on a chassis almost entirely made of plastic which turns out to be rather thick, robust and light (240 g): neither cheap aspect nor shell which sounds hollow here. Even if we can still see some marks on the hinges, we can say that the assembly has been done with care. In addition, Sennheiser had the good taste to choose a completely matt finish, therefore very insensitive to fingerprints

If you do not rotate completely flat (90 °), the ear cups can be folded down, making it easier to transport and store the helmet. A carrying case is also provided to protect it at best.

The HD 4.50BTNC adopts two types of pads: memory foam pads covered with imitation leather for the ear cups and a pad covered with a kind of rubber for the headband. If we greatly appreciate the thickness, elasticity and softness of the pads offered on the ear cups, we no longer regret the choice made for the headband pad, which lacks thickness and width. It is nevertheless a little more pleasant than those that can be found on other models, such as Beats’ Studio and Solo series , the U-Jays Wireless or even the Focal Listen Wireless . And above all, it does not tear out the hair. It is a bit of a shame anyway; we would have seen theon this helmet…

Audio

The Sennheiser HD 4.50 BTNC offers a convincing sound rendering, which, surprisingly, turns out to be a little more mastered by wire and without active noise reduction.

Let’s start with the analysis of the wireframe rendering and without active noise reduction. We enjoy a warm, natural and fairly precise reproduction. The bottom of the spectrum is balanced, although we can perceive a small preference for the extreme extremes, which causes a slight boost on the feeling of pressure, the seat and the depth of certain sources (bass drum or bass, for example) . The reactivity of the membranes is also quite good, which allows to keep a good readability, even if a little more linear behavior on the fall phase ( decay in English, just after the attack of a note) n ‘ would not have been too much.

On the other hand, one can be disturbed by the small seashell effect of the atria and especially the fairly pronounced lack of high mids, which reinforces the warm side and the effect of distance that we see on many sources. The timidity of the treble also contributes to this warmth of the sound rendering. We would have preferred them larger and more present, especially in the higher frequencies, in order to have something more airy. Nevertheless, the stereophony is rather well transcribed, in particular on the horizontal level.

CONCLUSION

The HD 4.50BTNC is consistent with its initial promise: it offers a good user experience and good sound rendering for nomadic listening in urban areas. Some points are still perfectible to rise to the level of the best of its kind. If the effectiveness of active noise reduction is not your priority, take a look at the Backbeat Pro 1 and 2, which are more regular on other terrains.
