Yeah, they are using Sennheiser transmitters (some are lavs some are full XLR mics )
Basically, I am using an SDR(RTL-SDR V4 with a small antenna) and SDR++
they have set frequencies that I have bookmarked and saved.
Funny thing, this allows me to listen to courses in other rooms, its quite fun to tune in and guess the class xD
