I'm looking for someone who owns the Sennheiser HD650 headphones who can give me dimensions. I'm wondering if they'd fit in the pelican 1200 case measuring 9.25"x7.12"x4.12"

Mine are about 7.75"H x 7.25"W x 3.5"D fully collapsed, not including the cable connectors, which are a little less than an inch long. You can squash them a little width-wise, so you might be OK.

In case anyone's still wondering, yes, the HD650 fits inside a Pelican 1200:
 

 
 
I made a little compartment in the foam to store the cable reducer, as well as the 1/4" plug so that it doesn't move around and scratch up the headpones.
