I was just restoring my PC and had an old bt dongle that had poor range but worked fine with my Cowin E7 headset while on the computer. Since I couldn't get the DG45 to work, I left it lying around for a few months. So I decided to try again. I went to the Avantree website, logged into DG45 and saw several support questions from people who couldn't get it to work. I installed the driver so I was sure it wasn't. A few key presses as recommended by the support team got me to the point. Thumbs up for supporters. That works great. I walked outside, closed the heavy double glazed sliding door, walked around the back yard and was greeted warmly. Very impressive. Updated 04/22/21. The only minor complaint I have is that the volume is a bit lower than I would like. Maybe there are ways to solve this problem.
