Can't believe I need to put a star on this to say my piece.  I'm not the altruistic sort that helps others make an informed choice on the basis of my own bad experiences. No, this is a rant driven by selfishness so that I can feel a little better.  It starts with the ipod 30G.  My rationale in choosing this system was that with 30G of memory, surely there was a method of conversion from CD format that would allow me to experience the clarity of CD in an MP3 or similar format - say apple lossless: no appreciable difference; and I've got excellent audio perception, I was off the charts with that audio test they do in school as a kid.  I'm like the audiophile with neither the money nor inclination to become an obsessed toss*r.  Obviously the earphones aren't gonna be the best so I figure I'd upgrade them.  Sennheiser are supposed to be specialists in this field, and the guy in the HiFi shop says you'll get the best out of your ipod with the MX500.  Sh*te.  These are considerably worse than the ipod freebies.  No bass.  Tinny. Crap. Crap. Crap. I'm goin on the grail quest now for decent earphones that deliver some base.  And I'm not listenin to any more reviews.  Half you folk think these earphones are gods gift.  Maniacs.  First things first, I'm gonna beat that assistant about the head and shoulders for spinnin bullsh*t, and reclaim my 25 (cannae believe how much they charged for these). Feel marginally better now.
