Some of the complaints have been submitted on Apple's Community Forum, described to be "Audio on problematic unit sounds robotic and distorted, as though there is corruption in the Bluetooth data stream" mentioned by MacRumors.
A MacRumors user claims that Apple Support has raised the issue to the company's engineering teams.
"I have been working with a high level support person who has assured me he is working directly with engineering. Apple has very much become engaged in this issue. They have had me do extensive testing of various conditions in order to document and troubleshoot. Further, there is an internal "Issue" board and tracking system for Apple support and this BT issue is on the top of the list. It was conveyed to me that this has become a very real issue internally and resources are now committed to its resolution."
