hello guys well after a lot of head-fi research and analyzing options available here in my country I ended getting the AKG K450s well the thing is with some bass frequencies the left speaker vibrates and makes an audible treble noise when i push the left side against my ear the noise sometimes disappear, I don't have any warranty here and the box was closed so they are new, they sound great but sometimes these noise is disturbing grrrrr!! 

they have like 30 hours of use now,  can I open them or adjust something? any idea?  is this a common problem with headphones?  Thanks!!!!

any idea? I feel like the noise has increased these days

what a shame for AKG quality.

It might be a loose part, or very likely just a piece of dirt/hair buzzing against the driver. If you can disassemble, take a careful look around. Some compressed air might also be useful.

hello, I just opened them and the driver is in a sealed plastic case so there is no access to it, I used compressed air and made different tests and the noise is still there

it sometimes with some songs and medium volume disappears what a pity

Hi,
 
I believe that Armaegis is probably right about the loose part - if there's rattling and it stops at lower volumes or when you press the speaker in that's what I would have guessed.

well after trying to fix them without luck I ended selling them today what a shame

I was also selling a shure srh440 that now Im gonna keep

although they are a little heavy and uncomfortable for work use
