Having 2 headphones plugged in at once?

[currly30]

I was wondering if it is safe to run a headphone on both of the outputs at the same time?

I didn't notice this till recently but both of the outputs on the Mainline produces sound at the same time. I often leave my HD650s plugged into the 1/4 jack while using the XLR jack to power other headphones. I thought the balanced switch worked like a kill switch between the 2 outputs. Is there any danger from having 2 headphones plugged in at the same time? especially since the HD650 are 300ohms and the other headphones I have been plugging in are around 30ohms. Would having such a large difference between ohms on the 2 headphones cause driver issues or cause improper amounts of power being sent to the lower ohm headphones?

It's unlikely that you're gong to cause damage unless you are listening to something like the HD650 and you have the other headphones still plugged in, as this will produce a very loud listening level out of the HD650.

The balanced/unbalanced switch moves grounds around but otherwise leaves the circuit alone.

Thank you for the response. Figured I just make sure .
