No, I haven't tried them, because I actually don't want anything in my ear if I'm going to be resting my head on my ear - let alone the headphone wires dangling around my face and getting twisted as I turn from side to side. That's why I'm so glad to have found the SleepPhones with just a single wire at the back.
The IE80's (and many in-ear headphones) wrap over your ears and you can easily have the wire meet at the back of your head and then it's just a single wire.
Understandable if you don't like in-ear though
