Just noticed you mentioned hiss, the answer is no it won't damage the phones so go for it.

Indeed. Tests will not prove anything either. Tests may prove this: positioning differences, manufacturing differences, differences in tips, and myriad other things. This is not a provable or disprovable item of audio - it simply goes beyond anything other than faith.
If you believe in it - go ahead. Personally, I don't bother believing it but for the sake of argument, all of my headphones get 'burned in' before I make reviews; I just don't want to risk the ire of believers.
