Regarding the Sennheiser: Headpiece: ME3-ew Belt pack and receiver: ew 100 G3
I like the headpiece because it stays in place, the sound quality of the system is excellent and I have never had a problem with it in 8 -10 years. Also, I recently purchased a "Compact Powered PA System" by the name of SRM 150. It weighs maybe 10 pounds, I can lift it with one finger, and the one speaker sounds great and fills a big room. Jill
