The headphones that they own are the Sennheiser Momentums and today I let my friend try them on. However, because the headphones did not belong to him, he pressed them pretty hard against his ear (trying to listen to something). This in my opinion made the earpads holders very loose and made them sound a little off i.e some parts of the music were missing/didn't sound as good.
My question: Could the pressure that my friend put on the headphones cause them to change or is it just me being paranoid?
I would also like to ask if anyone that owns the Momentums could try the song human by the killers and tell me which parts of the song echo and if the earpad holders of the headphones have some resistance.
