I have high expectation for these earbud , but to be honest , I get better sound with my stock ipod earbud equip with Griffin Earjams . the sound on the Sennheiser bud be tinny with almost no bass , unless you jam the bud so far into you ear canal that it be about touch you brain . also they have asymmetric cord length , so the right cord be much longer than the left one . it be weird if you be use to the standard setup with both side the same length .
