Recently, I have found that my headphones sound different. They feel... less powerful even though I only received a few weeks ago. I am using a Schiit Audio Magni amp and the headphones haven't gone through any trauma of any kind.
Maybe I've gotten used to the sound and don't feel the bass thump as much as I used to? Or maybe my ears are going out? I used to keep the settings at 1/4 turn of the amp knob and then 50% digital volume which gave me great results. Now I feel like this doesn't really sound that great.
I'd be interested to know if there is any software that is freely available to be able to test the output of headphones?
