Yes, this topic again.
My current understanding is that Airbus have an approved list of headsets that can be used on the A320 available which is at least 10 years old. I have since then heard many different things:
1.) The list is still a de-facto list, do not use any headset other than what's on the approved list.
2.) The list only tells us what has been tested and guaranteed to work correctly, you can use anything you like as a headset is not part of the installed equipment list (unlike the hand mic) and therefore not subject to certification.
3.) The list was abrogated and now Airbus approves any headset which has been approved by the appropriate authority (In the US, TSO approval is required).
So, in the year 2014 what is the correct way to understand the whole headset situation?
Thanks
