I love these headphones. They are the only kind I'll buy. I've been buying them for years now and they sound wonderful. The only problem I have with them is that a couple years ago they changed the design which used to allow you to control the volume with the remote and now they don't have that feature.
I LOVE all Sony headphones. These ones are no exception. They give a nice seal so I can focus on whatever I am doing, usually working out. It blocks out the noise of all the men making their grunting noises ;)
What can I say really - they're earbuds. They play music and the sound quality is decent. I gave it a 3 stars because Sony earbuds tend to crap out on me after about 6-8 months of use. Otherwise , I think they make top notch products.
