Hi,
 
A bit of a noob question here but what is the exact sensitivity of Sennheiser HD600?
 
Back in the day it seems Sennheiser reported it as 97 db/mW. All unoficcial online sources/reviews also say so.
 
However, currently the original online specs and manual say 97 db/1V.
 
In my original hard copy manual, it simply says 97 db at 1 khz.
Did Sennheiser do a sloppy job on reporting the HD600 sensitivity? I am confused..

According to Innerfidelity measurements (Tyll Hertsens)
http://www.innerfidelity.com/images/SennheiserHD600.pdf
 
You need 0.230Vrms for 90dB
This means 102.7dB/1V
 
Similarly you need 0.17mW for 90dB
Which means 97.7dB/mW

Lol, so the official specs from Sennheiser are very wrong. They updated the measurement units but not their value, it seems.
