Hello there blidd,
Thanks for participating in the Apple Support Communities.
As you're seeing this occur while connected with different devices, are you aware if you have your AirPods set to switch automatically between devices? In addition, have you noticed if this occurs when you receive a notification on a different device? If you're unsure about the setting to switch automatically, check out the information below and you can locate additional information here: Connect and use your AirPods Max - Apple Support
Switch automatically
You need iOS 14.3 or later, iPadOS 14.3 or later, or macOS Big Sur 11.1 for your AirPods Max to switch between devices automatically. Your devices need to be signed in with the same Apple ID using two-factor authentication. For example, while listening to music on your iPad, you answer a call on your iPhone. Your AirPods Max switch from the music on your iPad to the phone call on your iPhone automatically.
In some situations with macOS Big Sur, you'll see a notification about your AirPods Max on the screen of your Mac. When you hold the pointer over the notification, a Connect button appears. Click Connect to confirm that you want your AirPods Max to switch to—or stay with—your Mac.
If you want to turn automatic switching off for an iPhone or iPad, go to Settings > Bluetooth on that device with your AirPods Max on your ears. Tap the Info button
next to your AirPods Max in the list of devices. Tap Connect to This iPhone [or iPad], and then tap When Last Connected to This iPhone [or iPad]. To turn this feature on again, tap Automatically.
If you want to turn automatic switching off for your Mac, open Bluetooth preferences on your Mac with your AirPods Max on your ears. Click the Options button next to your AirPods Max in the list of devices. Click Connect to This Mac, and then choose When Last Connected to This Mac. To turn this feature on again, choose Automatically.
