Ear pads dt880 noise

[Laguro]

Hi all, bought ear pads for dt880 and they added "bzhhhhh" noise in about 180 hz and echo
What is the reason of this? Form or material, how do you think?

Is there by any chance a hair stuck to the loudspeaker?

That's strangely common on Beyerdynamic headphones.

Both channels or just 1 ?
What happens when you fit the old ones back ?
What happens when you put some pressure on the earcups ?

If you've had the cup rails pulled out of headband with removed earpads, the lower end of the cups could've snapped against each other, breaking the black plastic grid covering each driver. That's the worst case scenario..
