This headset provides clear sound, we hear many details. This is more a monitoring headphones, it lacks the density of the stamps, but for a closed helmet, filing is aerated. The bass is required, treble are clear. The headphones are comfortable, lightweight construction the air, so test time. But this helmet is a bit heavy for a mobile listening. At this price it remains a very good choice, with a fidelity of the spectrum (no bloated frequency ranges) ahead helmets like sony at low hypertrophied.
