From Sennheiser EW male connector (Hicon HI-J35S-SCREW-M) to AKG 3 pin TQG male (Neutrik RT3 MC-B)
I use these adaptors to use AKG and Thomann mics with Sennheiser XSW body packs. They do a great job. When connected up properly the link at both ends is secure and their length is just right - not adding any significant length.
After a number of gigs no failures and everything intact with the connectors still functioning as good as new.
It does what it is suppose to, but very expensive. If you buy this, make sure you test it as soon as it arrives. I bought 2 and one of them was not working. Thomann, as always, promptly accepted the return and it is solved
