Query: Sound quality is off

Over 1k+ review of an item with a 3.5+ rating, I thought these would be great earphones, but I was wrong.I bought the earphones because my current HP earphones( which comes with the laptop I purchased 5 years ago ) and my Zune earphones are about borken.After I recived the earphones I tried them on(5mins ago): small and confortable, thumbup. BUT the sound quailty is way off. I compared with my HP and Zune earphones, I can clearly tell the difference. Coby earphones output "high frequency" sound, my rock music sounds like they are screeming at my ears. Same music same volume, my old Zune earphones sound way better than the Coby ones. I bought 2 sets and I will return them. Maybe they don't cost too much but what good I can get if I will never use them.
