ジッパーケース

The little zippered pouch slides into my jacket pocket without any bulk, and the zip feels sturdy enough that I'm not worried about it popping open. My IEMs come out scratch-free every time, which is more than I can say for the soft bag I used before.

Tossed this in my bag for a flight and my in-ears came out exactly where I left them, no tangles. The pouch shape is compact enough to slip into a jacket pocket, which I didn't expect.

The zipper glides smoothly and the pouch shape keeps my IEMs from getting crushed in my backpack. Only gripe is there's not much room for extra tips or a cleaning cloth. Still, it does exactly what it's supposed to.
