These things are Total junk at this point

Another nice thing about the AKG NC is the passive mode where the NC is off - the headphones themselves provide great sound and can be used as a normal headset

I find myself having to switch to my regular apple headphones because these things are so uncomfortable for long term use.

When I turn on the noise cancelling feature, things are even worse, with a low level hum all the time.

I would have rated these 2 stars for the fact that they ARE comfortable for long periods(so long as I never have to put them around my neck)... except the bad things about these when you consider the high price tag are just too much.

Not the worst thing in the world, as they are still good headphones, but you buy these as your NC set

What is more is that these things are puny, tiny, annoying things to wear and the noise cancellation is a joke.
