My guess is you’re right about the pads getting worn out and letting more sound out. Can you get replacement pads for those rather than just buying new headphones?

I didn’t know it worked with wired headphones. My guess would be that you are correct and it doesn’t calculate for impedance.

My Grado 325e’s more than likely.

I love my Beyerdynamic T90s but they need an amp and so they’re less flexible for general use.

They’re Skullcandy brand. Not sure of the model Crushers maybe?

I’ve heard they’re very very bass heavy but I don’t have any personal experience.
