Soundproofing is very good.
This headset delivers a surprisingly wide soundstage for Intra. The instruments are well separated.
The bass sound is clearly put forward, but without excess. The highs also, but without sibilance (curve V). Mediums do not seem so far removed or suppressed. Metal, jazz, text songs, everything goes well!
The remote control works perfectly on my Honor 6 + Rocket Player.
In short, for the price, I'm happy.
Rest son of grinding noises that go back quite strong in headphones, which makes me take off a star ...!
