With all due respect, Mr. M. Night Shyamalan is a horrible director :|
I also wouldn't rule out a "damping material change for production purposes" in a year or two, say, from stainless steel to a form of black silk that will have absolutely no impact on the sonic character at all.
Did you even listen to them?
Concerns
Because of the high amplitude and sharpness of the peaks at 5.5kHz and 11kHz, we urge listeners to be careful when listening at loud volume or for prolonged periods of time. Most people will adjust their volume to set the midrange to a certain level. The 5.5kHz peak is 6db above the level at 1kHz. This is a doubling of volume intensity. As an example, let's compare the HD700 to the ESP950, a headphone which I've listened to at loud levels ~85db for prolonged periods.
HD700 (green) vs. ESP950 (red)
At 5.5kHz, we can clearly see that the HD700 is 10db louder than the ESP950. Noise induced hearing loss (NIHL) has been shown to manifest as notches from 3kHz to 6kHz. We are especially concerned with those listeners who do not notice or do not mind the treble characteristics of the HD700. We recommend taking regular breaks to check for any discomfort, ringing, deafness, or nausea. This advice is not restricted to the HD700, but all other headphones with similar characteristics such as the more aggressive Grados, Ultrasones, and some Beyers.
My curiosity regarding both the HD700 and the RS1 has now been quenched, thanks.
Not everybody seems to be sensitive to these effects. Otherwise it could not be understood that the RS1 has been so popular.
Just listen for a while to one of those headphones. Then go into a quiet room or use earplugs. If you hear a ringing in you ear, be careful. It may persist after a while.
