I recently bought these from Amazon since my existing Apple Earbuds lost a sleeve and I couldn't find a replacement AND I can't be without my iPod for travelling AND I can't stand the standard earphones they come with, just found a review on PC Mag about the bass.
I had been dissapointed with the bass they produce for the first week or so of use but then one day I was fiddling around and decided to turn them upside down and stick in my ears and they fitted a lot better, in fact they sank right in and the bass is now fantastic !!
The side benefit is i've got really clean ears now due to the fact they hawk out all ear wax when you pull them out but the danger I suppose is I might get an infection if I keep pushing them in that deep !
Anyway recommend them highly now
