Interesting, but I would be interested to see the true power output of the amp, not the peak amount of power it could output
it looks almost like a switch to share across three headphones.
Pretty sure its for only one headphone, as there is one typical balanced 4 pin, and two 3 pin jacks for separate left and right cabling. Donβt think it would have the juice (or be wired for) 2 headphones at the same time
I hope they got their input and output impedences mixed up!
