Query: My favorite headphones!

I've been using these headphones for years! As with all headphones, the wires are subject to breakage when pulled, so I keep an extra pair or two available. They last for 2-3 months of fairly heavy usage. I listen to audiobooks and music while I'm ironing, cooking, knitting and walking. I started using this brand and style of headphones when the children were infants because the earpieces do not block sound. They just sit comfortably in the outer part of my ear. I've tried earpieces that came with my mp3 player, but I can't tolerate the irritation from having them in my ears. Heavier headphones flatten my hair and block sound. These are definitely my favorite headphones!
