I was at Radioshack today, and I decided to buy a pair. They are very nice,
IMO, and look very good with my Zune. They sound good, and they're pretty cheap. I got them for $20, but I know they sell them at other stores for cheaper. (Didn't figure out until I got home

)
The only con, for me, would be that they sometimes fall out of your ears if you're walking or jogging. But, then again, all earbuds do for me, because I had surgery on my left ear. They don't make those earbud tips large enough!
