Hello, is there an adapter available to use existing Sennheiser EW series mics with the mic input of the DJI Mic. They have a 3.5 mm jack with a ring. Due to the ring it does not fit wide enough into the plug for mechanical reasons. In addition I think the Sennheiser jack assignment is different.

Same problem. Looking for extension. Did you find any?

Found an adaptor in Switzerland, but very expensive (ca. 30 USD), so it does exist (https://www.houseofsound.ch/sennheiser-ew-auf-3-5mm-jack-adapter.html). Also found a website in the UK that has. But maybe you should just chop off the head and put a new one.
