How to setup headphones and amp?

[kellanphil]

I have OneOdio A70 fusion headphones and I plugged it into my amp and sounds coming out of both the headphones and amp? Both the amp and headphones were gifted so maybe I just need to get better, not so cheap headphones/amp but I'm hoping maybe it's just the settings or something.

You trust our divination skills too much 

WHICH Amp? Brand and model?

Post a picture of headphone out.

Is it a Guitar or a Hi Fi amplifier?

Show the speaker output jacks/terminals too.

Any speaker selector switch on the front panel?

LOTS of questions.

The headphones wouldn't be at fault here, but rather what you were plugging it into.  What is the make and model of amplifier you are plugging into?  If you don't know, pictures can help us sort this out.
