If you like the style, get 'em.
I dug around online, and this is the cheapest you can get these headphones (the exception being the ugly tiger stripe ones, which I found for 30) with no shipping (as long as you buy something else for >$10). They actually sound pretty great, especially with bass-heavy music. Also, when you take 'em off and turn the volume all the way up they actually sound really good... like better than my laptop's speakers. They're a tiny bit uncomfortable if you wear them for a long time, but it hasn't been a problem for me, though I have heard other people complain hard about the comfort issue. If you like the style, I'd pick them up. If you think they look ugly, you can find ones with the same sound quality that are a little more comfortable for the same price.
