Query: Durable, Quality Headphones

I've had these headphones for about two months and I think they're great. I was really looking for something durable and these haven't let me down. It's been nice to be able to fold them up and stuff them in with the rest of my luggage. They still look like new even through all that I've put them through. Not being big on spending, I've gotta mention the lifetime warranty was a huge plus along with the price.Sound quality is also great. For the same sound quality you could easily end up spending over $100 on other brands. Sony has some nice headphones at similar prices, but they don't fit my needs as well. These other brands will make you sweat each time you drop them. I can just toss these things around and not worry about them.A small issue is the fact that these aren't over-the-ear headphones, so after about two hours of listening your ears will start to hurt if you have the adjustable "ComfortZone" set to firm. But don't fret, it is adjustable.
