Well I got fed up of waiting for one to appear so I've kludged up one. Behold my jacked remote with volume control!!

I chopped a WH-205 and used a Shure EA650 as the volume control. I took the EA650 apart, and soldered the WH-205 cables into it.




WH-205 litz cable colours FYI

Red = ring
Green = tip
Blue + clear = ground

I'd rather a cheap pot wasn't in the audio path to a $1700 headphone (or $1100 earphones), but even this is better than going via a jacked Bluetooth remote.

Still missing transport controls of course...
