(Airpods) Very poor connection/choppy quality between Airpods and Macbook
Thank you for providing more information.
Out of the BT profile we can see that your RSSI signal strength is low (borderline low).

About RSSI, it is used to measure the BT signal strength (also WiFi).
It is bit confusing since the values are invert. means the lower the number the better the signal.

As of this moment it is not clear why is it 72 !

As you say you are close to your Mac so the distance should not play a role in this case.

Your RSSI should be lower than 60.

The high 72 would explain intermittent connection.

As for why is it so high, it is difficult to determine from where I stand. In most cases it is just some interference from another device, like from the WiFi which also operates at 2.4 GHz band. Try turning your Mac's WiFi off to test.

If you whish to investigate Apple provides a way to do it.

Apple provides tools to actually test your Bluetooth in real time
.
It is on the Apple Developer site, but you must register/Log in to get them. You can find it under "More Downloads for Apple Developers"

Then download the additional tools for xcode 10
That package contains the Bluetooth Explorer.app that will analyze your RSSI signal in depth.

It will look something like this



Sorry I can not help you further at this time.
