I've historically kept my current rotation on stands for easy access, while putting the rarely-used models in storage. I'm now realizing the drawbacks of this approach - those on active duty get dusty and take up lots of room, while those in storage aren't easily accessed if I do want to use them at some point. So I'm thinking of putting everything in storage - but keeping that storage readily at hand, somewhere near my audio rig. I feel inspired by the case included with the Ether C and even the little V-MODA case from my M100. I was thinking of grabbing something like this or this or this (you get the idea) and then labeling each one, and storing them all in a cabinet or something. But with a dozen or so headphones (or more) this will add up, and I'd also need to be sure the case fits every headphone out there. Most of these cases are from no-name brands and I'd hate to buy a dozen of them only to find they either A) don't fit all my headphones, or B) have crappy quality and fall apart quickly. I know I'm not alone in this - some of you folks have even more headphones than I do. What do you do to keep them manageable?
