New hands free CB

These units work well, we have many in our car club. This model was for a friend and has a wired headset and is a bit simpler than the Bluetooth model. The only thing I see with this model is people getting out of the car and forgetting they are plugged in. I have the Bluetooth model in my car and it has to be charged with a USB port. I have never run the battery down enough to be an issue. It can take a minute or 2 to connect. Most people don’t realize at first that you don’t hear thru this headset, you only use the mike. Sound still comes thru the radio or external speaker. Most of us wear it around our collar instead of over the head, more comfortable and the hats and earmuffs fit better.

I love it its working good

Works good

I operate an excavator, and I zip tied the head set to the side of me and mounted the button to a joystick. I'm in and out often so wearing it was inconvenient, but dealing with 5 to 7 dump trucks , it make life more efficient.
