My husband has had these headphones for years. They seem to be nice headphones (full disclosure--I am no techie) BUT the material around the speakers was awful. It was flaky and gross so we never used them as we didn't want to have black bits all over our hair and ears.
I'm sure I'm not the first to do this, but I had this idea in my head to crochet covers for years. The only problem is that I don't crochet. Not well at least. The other night I decided to just go for it. One side turned out funny (I didn't think to keep track of what I was doing so I just winged both pieces), so I may redo it. Overall I think they look kinda fun? I may crochet the headband piece too just for kicks.
