Ha! The new ones I have are the K271. About 10dB more sensitive than the
older ones due to an impeadnce differance, but they're still not as
sensitive as the MDR7506.

They also have a detachable cord that plugs into the left earcup and a
micrswitch that turns the phones off when you take them off. Have you ever
blown up a set of phones because you forgot they were plugged in and someone
wnated to listen to the mix or solo REALLY LOUD.

No, but I've had singers who want to hold one earphone over one ear
and let the other one dangle. Do you have to hold your head a special
way to get the headphones to turn on in that mode?
