Yeah, same problem. Bose 700 NC. I've had them for 1.5 weeks; love the sound. But itchy, bumpy, flaky rash developed on earlobes as well as on head under earlobes after a few days of extended use. I'm guessing either irritant contact dermatitis or allergic contact dermatitis, probably the latter (earlobes were also slightly swollen and warm to the touch). Looking for a workaround (replacement earpads?) as, again, I love the sound. I guess I'll contact Bose or something.
