|are there any suggestions for keeping phones safe, esp how to pack them in the case?|
I just used the headphone manufactures foam inserts that my HD600's and K1000's came with and fitted them to the case. The HD-600 foam inserts were the perfect height already.
I used the plastic packaging that ATH-W100's came with and did the same.
I already had the fabric around the house from years back so I added it for a nice appearance. That idea came from my ATH-W2002 case.
