Hardly bass, best, strong tone, but already above 6 kHz does nothing more. Sounds like a bass / midrange. Legal insubstantial sound without brilliance. The blatant Basschwäche may still be acceptable for the nightly audio book, but at the latest when exercising, or walking, lack of frequency range which is then masked excessively. Even the Beipackhörer the Cowons MP3 player, sound much livelier and above all balanced. Each IEM on the quality of CX-215, CX-300-II or EP630, EP830 ... UE-200 ... allows the Marshall far behind. When I think that the Soundmagic E10 in the same price range as the Minor plays, the performance of the Englishman solves even Fremdschämen me out. The comfort is very good though.
Since I bought a "returns", I can not rule out a defect, but then he would have on both sides of the same defect.
