Updated to latest firmware. Rebooted them and even done a factory reset per Apple instructions. They are cutting in and out while listening every so often. It’s extremely quick but enough to annoy me a bit while watching the new Dune movie. I have Sony MX4’s as well and no issues with those like this. Hope I did not get a bum set? Return is no problem IF need be. I got them at Best Buy with AppleCare. Will continue to monitor but wanted to know if this is a possible issue right now? I only ask this since iOS 15 is pretty new still and all my devices are using it.
