I'm not knowledgeable enough to judge the helmet on its sound reproduction, but the sound is generally very satisfactory, with no particular predominance of low, mid or treble.
Rather, it is the object itself that I'll comment. My only complaint size goes to the hoop.
On photo, one has the impression of comfort, bearings appear very padded. We imagine the cozy.
Actually just press barely above to feel the metal hoop underneath! There is no padding, and inflation is frankly bogus.
From the air! A simple foam pad would have ensured a perfect comfort!
Depending on the shape of the skull and the mass of hair, we feel a little or no discomfort. For my part, I occasionally (not more, hopefully) the top of the skull that heats is very unpleasant and I have to move the headset to erase that feeling.
In contrast, the earbuds are perfect. Very flexible, but sufficiently thick and comfortable to wear. They heat little.
The headset itself is very light, soft, it does not tighten the rather good finish (except the attachment of the wire, we say that not much could blow it), all the materials used are opting for lightness and although the building looks ok, it is better to be cautious and not to manhandle the object.
Personally, I love the design (brown / gray). Even if the gray is not as chrome on misleading pictures. Grey is matte with a slightly satin sheen.
But the result is really nice, retro look, without being as-tu-vu.
Anyway, here. A helmet at this price must be irreproachable in terms of comfort. It would be if the hoop was properly padded. For me it is insufficient, hence the note. It remains to know if this is a concern for my copy, but to view videos and photos, I do not believe at all.
I do not understand that one can neglect the arch, while it is simple to ensure optimal cushioning, without yet appear unsightly.
For this reason I take two stars. I would have put 5 otherwise.
