Good sound, practical, iPhone-compatible

After a tasting of 3 Sennheiser headphones as a successor for my PX100, which unfortunately has a cable / connector loose contact, but then I decided to go for this. Good sound, slightly better than the PX100, and from the comfort better than the MM70i where the remote control pulls down the cable by the weight.
+ Sound: Good spatial effect, authentic voice reproduction, Bass ok (might be a bit more)
+ Comfort: relatively easy, can be folded, can also be used in the subway, because the ear cups attenuate ambient noise very well
+ IPhone-compatible and the remote control is easy to operate
- Cable relatively thin, does not make very high-quality impression, but a star deduction
