Ive got some cx300s , had them for a while now, good 4-6 mnths. One shorter ear cable and one longer to reach around back of head. This seems to help stop catching the wires when worn. As i use them on my desk is still catch the wire and so far no damage, ive caught them pretty hard as well

.
I saw the Shure guys doing the upside down thing at the London what hifi show. Looks like hassle to me. Shure(ly) (

)the wire at the top would pull the phone round?
