Query: 3 of these have failed on me

These were the first type of earbuds that I use with my iPod. I am a fairly delicate user but there were times that they would fail on me. As I appreciated the sound of these earbuds I would go out and buy the same thing. After the third break on me, I gave up and decided to buy a different earbud.
