I was reading this thread because I was interested in opinions on the quality of earphones. Thanks for all of those who rang in. It's often hard to get good honest feed back on the quality of products. I hate to buy something, head home all excited, just to be let down with a crap product.
Maybe those wanting to debate the pros and cons of use while riding, should start a thread on that subject.
I also currently have the sony, MDR-EX51LP,. Im a little disapointed in the sound quality for general use. But then im mostly deaf from years of listening to really loud rock and roll.
