These are really nice earphones for the price. I use this on my iPod, the iPod earphones are OK, but I wanted to upgrade. The goal was to get a nice pair of headphones without dropping a lot of cheddar. I did my research and found these on CNet reviews.These really are a great pair of earphones. It is really amazing the sound that is produced with these earphones. Also it comes with different sized inserts for a snug fit. They will not fall out of you ear while working out.Really a great pair of earphones. Highly recommend it.
