Does anyone own an iPod? I'm having trouble finding a good pair of earbuds. The standard earbuds supplied by apple are absolute crap. I purchased a pair of Sennheiser MX500s and they were significantly better, but still lacked clarity. I then purchased Bang & Olfusen's earbuds and they were actually worse the MX500s. They offered more clarity, but was significantly lacking in the low end. I realize its hard to get great quality from earbuds so I was hoping someone would have a suggestion. Has anyone tried Shure's earbuds? They range from $80 to $499. Anyone?
