These would be used in an office, so not moving around, maybe the creaking won't be much of an issue for me. Glad to hear they are fairly comfortable, I am going to listen to the Momentum M2 today, our Best Buy finally got them in, and will see how they fit. These seem like a great choice though. Thanks for the info!
I haven't heard the momentum 2.0. They were on my short list, but I got the HP50 for almost 1/3rd the price, used. I would guess the momentums are more comfortable, and soundwise probably comes down to a matter of taste. If I had to pay full price, I would probably go with the momentums because I think Senns build quality has stood the test of time
