Xvive Wireless gear

I chose this for use in live sound applications.
I use this with both headset and handheld mics.
There are no other comparable products in this price range.
PROS:
1: Can be used with any dynamic microphone--whether headset, lavalier, or handheld [condenser mics need not apply]
2: Small footprint on sound desk since the receiver plugs directly into the mixer instead of being a box sitting to the side taking up additional space.
3: Both transmitter and receiver have internal, rechargeable lithium batteries, so no changing of batteries is required.
4: Transmitters/receivers have channel selectors for up to six channels, meaning one can use up to six of these at once.
5: Manufacturer is very good at responding to customer inquiries.
CONS:
1: Can only be used with dynamic mics.
2: XLR connection on transmitter limits choices of headset mics.
3: Transmission range limited to less than 100 feet.
The pros still outweigh the ocns on using these--especially in small settings such as coffee houses, small churches.
