I had after I now months wertigere something used in-ear earphones from Bose, "forgot" that this particular, are small in-ear earphone very individual and are offered in extremely different qualities. These earphones are priced although not exactly dirt cheap, but the sound quality is so bad that even the most diverse supplied silicone adapters for the ear to tear anything. I would recommend these earphones maximum for listening to audiobooks, provided of course that to the guy the adapter fit what. With my rel large average ears never been the case. Can return to this "Schmalz drill" from hygienic reasons surely not.
