Thanks Ty for the reply and the info.
My camera is the Canon R5 and has a stereo unbalanced 3.5mm jack. Likewise if I use the Rode Wireless Go II it also has a stereo unbalanced 3.5mm jack.
I’d like to pick up a Sanken COS-11D based on a recommendation from a friend, so I suppose I just need to know if I need to get the Sennheiser-compatible 3.5mm end or the Sony-compatible 3.5mm end.
Thanks again for the reply, appreciate all your knowledge!
