I have bought these in-ear headphones for my Sandisk Sansa Fuze, because me the supplied although the sound enough to the device, but sit badly in the ear. So I wanted to have a few in-ear earphone, the sound playing about in the same league. After the bad reviews on the earphones of the Sansa Fuze and the good to the HJE 170, I thought that the HJE 170 as in-ear would suffice handset. Far from it ... the simple listeners of the Sansa Fuze nevertheless sufficiently and bass and mids, so they seem to be missing entirely in the Panasonic. The HJE 170 sound like some cheap 2,90 listeners from the street corner, tinny, shrill and garish, basses are completely absent. This product is definitely not worth the money.
