J KPro Headset Headworn Microphone MIC-J 071S Compatible with AKG Samson Wireless Transmitter - Mini XLR 3Pin Connector

Can I use this headset mic directly connected to my mixer through a snake by using a gender changer adapter from mini xlr to xlr? Would it work?

Does it use a 3 pin or 4 pin XLR connector?

Can this headset be used with telephone

Will this mic work in a gym with other wireless mic's being used?
