Query: Great earbud design

I bought these headphones specifically for running. The standard white earphones that came with the iPods would stop working, I guess because they get wet with sweat. I had never used this type of design before and it is simply great, the earbuds stay in place perfectly and are very, very comfortable.For a while I could not understand why the chords connected to the earbuds had different lengths, and the longer one was kind of a nuisance while running, flapping around my neck. I recently realized that if I placed the longer chord behind my neck and into the ear, the fit would be perfect and the flapping problem was gone.One minor problem is that the chord does not lose its coiled shape, and it tangles very easily; it took me several minutes to unravel the cables before a run until I decided to wind it around the iPod.Sound quality is very good, at least enough to enjoy during a run.
