Great Product, Short Life
I have to rate these earphones as unsatisfactory since I needed them to last more than 6 months.
Pros: These earphones worked well and fit nicely. I liked being able to adjust the volume w/o having to find the player's volume control and I liked the clip to fasten and control the cords.
Cons: However, after about 6 months of use instead of being stereo earphones they became mono because the right earphone stopped working. That was, of course, quite annoying.
