Yeah it's not like any of them is too low. I just wanna know the science behind how something with 250mw into 300ohm compared to 7mw into 300 ohm only is 5db louder.
I would put the source (pc?) and the player at full and see what gain setting and volume level gets you as loud as you need on the r70. I suspect you will have oodles of headroom on the the topping. Maybe less on the Behringer.

Both of them gets alot of headroom. Behringer at 50% is too loud. 30-40% is enough. 50% at Behringer is -15db low gain on topping

The difference is max 15dB. 10dB is a doubling in perceived volume.

I already explained this. There is NO other explanation.
Yeah with the Bose it's maybe 15db and with r70x 5db. So 15db more is 35 times the power. That's the case with the Bose. However the r70s it's only around 5db.

Its a gain thing combined with the high imp of the R70X and the high output resistance of Behringer (so volateh division differs between headphones) which has no effect on the Behringer where with the Beyer Bose it does.

Forget about % of volume controls. It literally says nothing.

You are comparing a high output Z, low current crappy headphone amp section with a low output Z, high current output stage and use 2 different imp headphones.
One is low and the other one very high. So you are basically comparing 2 totally different situations which, because of the various differences, have different results.
