I thought phones made everyones voice sound bad?

I’ve noticed that everyone’s voice sounds different over the phone, and it’s almost always higher pitched and makes them sound younger. I thought this was the case, until recently, I was talking with my gf, and she said my voice sounds deeper and hot over the phone? wtf? I thought phones trashed everyones voices?

What have people said your voice sounds like on the phone?

Mods, please throw this in social when you get the chance
