Yes, I tried that already. And although XLR input and Single Ended input. The hum is always noticeable with this 2 headphones. And when I plug in an W3000ANV a hum is there but very very low and you can only notice it in an absolutely quiet environment. But with TH900 and AKG 812 which are although efficient headphones the BHA1 is dead silent.
