2 headphones, 1 amp?

[Kalupaw2]

More curiosity rather than practical application, but is it possible to use 2 headphones in one amp? I have a topping a30 pro with 2 outputs. If I was to use both outputs at the same time on different headphones, would this cause issues?

I imagine you'll get sound out of both. I do on my 789. If they are particularly hard to drive headphones it might struggle at high volumes with both.

I have a Benchmark with 2 outputs and have used both simultaneously without giving it a second thought.
