Hi all,
 
I need some help regarding the AD900. On the right ear cup, behind the small velvet thing, the driver (?) seems to be loose. It can be slightly depressed unlike my left ear cup which is quite sturdy in place (can't depress nor feel loose).
 
While shaking the right cup a little, I can also hear the internal rattling.
 
Is it suppose to be this way for other AD900 owners? If not, I'm going to try sending it in for service.
 
 
Thanks.

Slide pads off
Take small screw driver and remove the 4 screws on the inner side of the cups where the pads would of laid.
Lightly pull the are off and the driver with wires will come out but on completely
There are 4, maybe 3 screws holding the driver in. - while you're here, remove foam if not already gone.
Tighten
Work backwards
 
That's about it, but I'm still not sure what's your problem. That's how to tighten the driver into it's holding area

Ok. Reason I'm asking is because I just bought this for around 3 weeks with minimal usage. So if it's some sort of defect, I'll just bring to the service center.

I really don't know what's going on. You might just be forcing too much bass or something is jingling around near you.
 
You need to to describe what's happening in more detail.
