The hinge pin popped out of my refurbished HD800 so instead of taking pictures of my earpiece that was off the headband I went instead into complete life saving audio mode and put the pin and the spring back on. They looked back to normal but the thought it could happen again off warranty scared me. Plus the serial number 8500 clearly dated the HP's as old. So I gave Crutchfield a call and they told me to send them back. I was reimbursed the full amount and moved on.
After a few days I started to miss the HP's and given the speed and ease of returning them to Crutchfield, I bought new ones this time around and with a serial number >25,000 I am feeling my life is more complete. So I am once again on the HD800 thread, minus an additional $400, and so it goes on Head-Fi.
I still didn't get mine yet. The company i ordered from are waiting on a batch from Sennheiser. They probably wont ship till the end of the week. The waiting is killing me, i ordered 3 weeks ago.
