The Sennheiser manufacturing quality seems to go! The headphones fit perfectly in place during my jogging, even at high speeds. The remote control works without problems on a Samsung Galaxy Note 3 for example. As against the sound is different from my Sennheiser Momentum In-Ear Earphone (very good from that point of view for the price): more serious and less dynamic I would say. Not necessarily obvious to correctly place the rubber feet first, try several positions because it is clean the ears of everyone I think. Otherwise the small clip to hang clothing and avoid the cord lugs around in every direction is welcome.
