Perfect for storage of router bits. I have high arches too and can actually feel arch support. Ive tried several different types of earbuds and these are by far the most comfortable. Love that it covers some of the white so they aren?t as noticeable. My husband wears ear plugs at work each day. This thing is perfect, did everything I wanted it to and its adorable. It feels cheap plastic and when I open the apple case the top protective case pops out. Updated Review:Not minutes after I wrote the review below I fired up Warframe to do some more testing in game and about 2 minutes in the DAC power cycled. They are so cute and stylish. Rack is pretty sturdy for a low cost purchase.
