Firstly Happy New Year everyone!
I use a Zoom UAC-2 audio interface with studio monitors but like to mix on Sennheiser HD650 headphones. The problem is they are 300 ohms and the headphone out on the Zoom can't drive them. I do have a headphone amp but it only has line in, so at the moment I have to unplug the monitors and plug into the headphone amp which is a real pain.
Can anyone suggest a way to switch between the two outputs - Monitors and headphone amp (or another way to connect it all up)?

You could try splitting the line output of the UAC-2 with y-cables. Or buy a line-level audio switch though these can be expensive if they're made with relays. Third option would be to build a switch yourself using a DPDT or 3PDT-switch.

What model headphone amp is it?
Normally, you would leave the monitors plugged into the audio interface, and run a stereo cable from its headphone out to the input of the headphone amp.

Line in can take a headphone out as input. Trust me, I've done the math... So headphone ouf of interface goes into line in of your headphone amp. Maybe you need a 1/8" TRS --> RCA cable..

I use this with my 650's:

Level does not make silly high level on 650, but more than enough and more than average.
I use -12dB level out on RME headphone out, there is no volume knob on my interface.
But it should work on others as well.
-10dB line level feel a bit compressed, so don't recommend that. Otherwise normal line outs could be used.
It is designed to take record out 0.3V from normal hifi amps.
If you're not on a budget:
