Use of adapter for GA headset to Airbus XLR plug

[heav1i]

Hi there,

I haven't found the answer yet, so I'm asking my question here (hope it's in the good section).

So I'm actually flying on the Airbus A320 and I want to use my Bose A20 but it's a twin plug headset as I used it to fly GA aircraft.
I found on Amazon an adapter from GA to Airbus XLR (looks like a little box) and I wanted to know if I can use it on the flight deck.

In the OMA of my Airline it's written:

Personal headsets may be used provided they are compliant with either:
• FAA TSO C-139
• ETSO C57a
• EASA Form 1

As I understand it, the certification is more about the headset rather than the adapter. Hence, I can use any of them as long as they don't affect the headset, there is no need for any certification.
Can somebody correct me about that, because it's not clear whether I can use it or not?

Thanks!

I suggest contacting Bose about this. After all the manufacturer ought to know their product.

The A20 was originally available with a couple of plug options, including XLR. If you still want this, you need to get a newer A30 as they don't offer it for the A20 variant anymore. There are adapters on the market but not from Bose. You could ask Bose if your headset can be converted to XLR by them, but that means that you cannot use it for GA flying anymore.

Actually, the question of whether you can use the adapter is one you should ask within your company. The rule is in their manual, so it would be best to check with them if they allow it. Depending on the specs of the adapter, it may not meet certain standards in shielding or material use for example.

I've used the A20 on the A320, just did it, and works no problems.
I had the helicopter edition where the lead has a connector that disconnects the rest of the cable to the plug, so in effect can swap the end out.
If memory serves me right it was a mini din 5 to XLR cable adapter?
