Wandered into Old Navy and found a wall display of "Techno Hoodies" on sale so I bought one. Because I listen to my iPod while walking the dog, doing housework, falling asleep (but only sometimes). So I thought I'd try a zippered hoodie with built in earphones.
I love it! The earbuds are wired through the drawstrings, and are as good as the ones I usually use: hardly Bose quality, but good enough for me. The connector sits in the front pocket, which is large enough to hold my iPod Touch, and hey presto! I have audio without a dangling wire to get caught on things and rip the buds out of my ears!
An added feature is that I can plug into my computer as well, without having to untangle wires and sort the plug from the earbud ends. It's incredibly convenient. The hoodie is rather light weight, not the warmest sweatshirt that I own, but fine for layering and wearing in the house.
The only drawback? I only bought one, and it does have to go into the laundry occasionally. And they aren't available on the website anymore.
