Thanks for the video took them apart and could not find anything loose in them I guess it is just a blown driver. any Ideas on where I can buy a driver? Looked on ebay and on Sennheisers website. No luck in finding one yet.

Thanks for the advice any clue on how to get them apart? I don't want to just go tugging on stuff and end up breaking them for good.

Hi I recently have developed a issue with my Sennheiser HD 555s. Every time I listen to anything with a decent amount of bass or even a deep voice it my right ear seems to have some vibration in it. It sounds like there is a piece of loose plastic in it. I was wondering if y'all could help me...
