Those sound like Sennheiser PX-200s. Let me say they are pretty much worthless on an airplane. My E2cs went back to Shure since they were worn out, and I sorely missed them Tuesday when I flew to visit my family for Thanksgiving. I'm not looking forward to the flight back without my E2cs. The Senns can't isolate your ears well enough, but the Shures can cut out airplane sounds quite effectively so you don't have to turn them up so loud you might go deaf.

The PX-200s work on a bus or train but would be awful on a plane. I ended up giving up on listening to music and just played sudoku on my iriver.
