these hurt my ears after 30-40min. at $5, definitely give it a try. Just wanted to share that from my experience, they're pretty uncomfortable. I'm used to the CX200/300's, have a pair of the M9P and a pair of jvc HAFX40's, and these monoprice ones are just unbearable compared to those. I've never had problems with earbuds and they've always stayed in, but they just hurt the roof of my ear because of how big the earpiece is. Sound quality wise, it's similar to the 200's, but with more bass.
