I wanted to use the adapter in combination with the Røde SmartLav. Until now, I used the RødeRec app on the iPhone, which has done well as a mobile audio recorder. The synchronization of the external sound is very good in Final Cut, but I wanted to record the sound of SmartLavs directly into the Canon XF100. As I discovered when ordering the SmartLavs and subsequent films with the Canon that no sound on the camera could be heard, I started first smart about TRRS and TRS. Because finally the adapter is available, I ordered it immediately, hoping to finally be able to feed the sound directly. Wrong! The Canon XF100 absorbs sound via the MIC terminal, although she realizes that something is connected. Also on Macbook no sound signal is detected. Wanted to do voiceovers with the SmartLav here. When I joined out of curiosity the SmartLav + adapter to the Canon 7D, the big surprise came - it works!
So I advise anyone who is not working with a Canon DSLR and SmartLav or other TRRS Mics wants to use his equipment to take good care! I keep the adapter yet, if I want to film something with the 7D. Now it remains for me to continue the app + SmartLav and a Shotgun XLR. Nevertheless I forgive only 2 stars because of limited use and for 12 quite expensive.
