I acquire a pair of these that be discard at work , so I think I would try they to see if they work . not good -- tinny and wimpy sound . I almost throw they away , but think that I have some large ear tip -lrb- these come with what I assume be the medium tip , at least they be not right for my ear canal -- and yes I wash they throughly -rrb- and why not try they to see if that be the problem ? well , the large rubber tip I have for another set of phone fit , and totally solve the problem . these be great little phone if you can get a good fit . they be better than my $ 200 shure , and rival the Denons I mostly use when I be not downstairs with my sennheiser . I also appreciate the beefy wire and substantial connection , which they share with my shure professional in-ear . for $ 12 ? these be a absolute steal .
