I’m using an M1 MacBook Pro with 11.1
I've used three different Bluetooth branded headphones and all exhibit the same problem. Intermittently, there will be a glitch in the audio (doesn’t matter the source). Not a disconnection, just a momentary glitch or gap in the audio every files minutes.
Anyone else had this issue?
Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?
Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:
• If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.
• If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.
• To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.

In addition, if you are in an extremely busy "network neighborhood", such as an apartment building, there may simply be too many Routers and traffic on 2.4GHz band for proper operation of bluetooth devices without dropouts.

How many networks are in your neighborhood?
That information can be obtained by holding option key while clicking on the Wi-Fi icon in the menubar. In most recent macOS, you need to make a choice off the menu that appears to see the networks.

If you wish to communicate with an Apple employee, use the "contact support" link at the top of any forum page. That will steer you through some suggested articles, then on to an Apple support agent, who is an Apple employee.
This isn’t the answer. There’s absolutely no USB devices plugged in and only the Bluetooth headphones are connected.
Are you an Apple employee? Seriously, it’s buggy. I’ve had MacBook pros for years and this is the first one with this problem.
I don’t remember it before 11.1 either.
