I discovered something interesting today. The UE 10vi cable I'd had for ages wanting to get reterminated to use with my JH13s works on the JH13s with a minor modification. You just have to circumcise it to expose more of the pins, and then it's just dandy. So I now have JH13vis
I have jh13s, but they're not headphones, they're IEMs. I traded my HF2s to gene ages ago, and sold the others even longer ago. I just don't use headphones very often.
