If you want to have very little on and around the head and not super high acoustic claims has, then the particle is optimal.
Unfortunately I have very small ears, so the bracket is dependent (who is with me the way clear transparent) not open ear, but is a few mm over it. For me, the aufstülparen hooks (made of silicone, which is then in the ear squeezes under a groove ear since then slips guarantees nothing more) much better and which I have always still that of other headphones left.
Sound is OK, slightly dull, but with one ear because you can always expect a miracle.
Making calls was also OK, no reverb or demolition.
It is still a small charger cable (mini jack from USB) and the instructions in English and Asian characters.
