I've gotten two headphone/IEM cases recently - a beautiful leather one from Valentinum from Etsy that is 10cm*10cm*3cm and a IEM Case by TinHiFi that is 78mm*36mm*57mm.

I love both cases, but neither works for what I need them for. The price includes shipping and PayPal fees. I have lots of feedback since I've been here for a while. I love the Valentinum case! I really wish I could find a use for it since I waited over 6 weeks to get it.
