Beyerdynamic TG100 Belt Pack Wireless Microphone: Amazon.co.uk: Musical Instruments (http://www.amazon.co.uk/Beyerdynamic-TG100-Belt-Pack-Microphone/dp/B00LPHGM0Y/ref=sr_1_11?s=musical-instruments&ie=UTF8&qid=1430934835&sr=1-11&keywords=wireless+belt+pack+microphone)

Just wondering if anyone has any experience with this product?

I have no experience with Beyerdynamic wireless systems. But if considering a low-budget system, I would recommend you read the below thread prior too.

Thank you that was very helpful. I appreciate that it's annoying for people to come over and over and ask the same stupid question so thank you for your time.

VHF radio mics went out of fashion years ago.... are the frequencies still legal?
