For some reason, the USPS shipping site (and Amazon) were telling me that the headphones I ordered would be delivered on the 19th. I was pleasantly surprised to find an Amazon.com box waiting for me at home yesterday. The headphones are super-comfortable and I am using the medium-sized earplug thingies. They block out surrounding noise, letting me hear the music with greater clarity. The bass seems pretty good too, which I was wondering about. I left them plugged into my laptop with my iTunes library running thru it all night to break them in, and they should sound even better today.
