Here is the link KOSS KSC75 @ RadioShack $5.47usd !!! - Head-Fi: Covering Headphones, Earphones and Portable Audio

I just called my local Radio Shack and they have it for about $6.57. That sounds good for me as an extra pair to have around

This probably set some kind of record for price/performance ratio.

need a portable pair of headphones. only to be used with ipod. no amp. go for these on black friday or px 100? planning on using these in school so whichever one leaks less noise will probably be better.

If I did not have, uh, upwards of 6 pairs of KSC75s, I'd be all over that like something on something else.

cj, PX100 hands down. It's got a much smoother sound, I found the KSC75 shouty in comparison.
