Driver downloaded and installed Prolific USB-to-Serial Comm Port (COM4) also tried COM3 and 2 Software downloaded and installed The above looks correct therefore What are the Port Settings? or is there another issue I'm getting really fed up with this, at no point did it say I had to buy additional hardware and install software to get VOX to work.

9  I recently purchased a Retevis 2 Pin PTT Mic Covert Acoustic Tube In-ear Air Acoustic Earpiece Headset off Amazon for work (were use Retevis H777 radios) but when I tried it, my audio can BARELY be heard. The sound can be heard up to the point until it connects to the acoustic tube, at which point I can hear hardly anything. I really like the style and comfort of this earpiece. What could be the problem?
