Schade, Philips. Even if you have some insider otherwise in range (above all the Fidelio X1 or SHL3300): these earphones are an acoustic torment I have no long-term experience, because once again returned.. Design and feel are not objectionable, the durability I can therefore say nothing, however. By small lateral openings comes from these in-ears unfortunately a very middle-heavy, mushy-muffled sound that has no space and at least fails me every listening experience completely. Since not even help the argument that it is only for the treadmill and not to listen to the hi-fi system. Even for sports this sound quality is too bad. Comparable to the earbuds that are distributed in the aircraft.
