Possessor of pro HD212 that we no longer find, I was looking for a fairly dynamic headphones and Basseux (but not in excess). the advantage now is that all music sources (mp3 walkman, smartphones, chains hifi etc ...) have équalizeurs which then allow helmets to become versatile. I wanted to base a good audio quality, but it frustrated me to have to put 200 euros ... In the radius of a specialty store, fifteen helmets of the same category but of different brands (in the age of 40 - 100 euros) were exposed at the disposal of the buyer leaving him the option to connect to a smartphone via the jack plug left free. I have them all tested one by one, to retain only one which is largely different from the other issue sound rendering, balance and dynamism. After it is often said that the sound is a matter of taste .. I ordered it immediately on amazon because it was cheaper than in the store where I had tested. This helmet is a bit "plastic" but as I know sheinneizer is robust helmet (I kept the previous 10 years) so I did not hesitate to re-invest in the brand and especially at this price.
