In response to my original headphone case post: http://www.head-fi.org/t/748334/hifiman-he1000-planar-dynamic-flagship/5385#post_11799542, I found a few cases that fit the HE1000 to various degrees.
The Marc Jacobs Pretty Nylon Tablet Case ($68 or lower at places like Nordstrom Rack [http://www.marcjacobs.com/pretty-nylon-tablet-case/M6PE007.html]) is thickly lined inside, and is a very snug fit for the HE1000, as the headband needs to be pushed down slightly so the case can fit. The case is a good choice if you want the utmost in
tight portability.
The A4 Cushion Case ($1.50 at Daiso Japan) fits the HE1000 and cables, provides dust and light protection, but will not provide much protection in the event of a drop.
My favorite is the Rebecca Minkoff Tablet Case - Black (purchased on sale at a Windows Store). It fits the Windows Pro 2 perfectly, and fits the HE1000 and cables perfectly. The case is padded neoprene, has a soft fleece lining, a removable nylon strap with strong metal hardware, has a pyramid design on the outside, so shock dissipation is exemplary. I see one currently on eBay (used) for $10.00. Great price because usually the Minkoff case costs over $100. So, after writing this I thought it's such a great case that I purchased the one that is $10. I do see a couple on eBay (Red and Blue) for $19.99 to $29.99 which are great prices.
