Acc. to Beyer they are 96dB/mW and at 600 Ohm that would make it 98.2dB/V so I set it at around 100dB/V.
It also depends on how efficiency is determined.
With noise in a certain bandwidth, at 500Hz or at 1000Hz.
Then there is product variance as well as well as measurement error (calibration).
Differences of a few dB are not uncommon.
