I wonder if you can tell me how you got the iPhone to stream music over Bluetooth
This audio panel is superb in every respect, and not all that expensive to retrofit especially if you already have a Garmin 340 or other PSE 8000 series audio panel.

Bose A20 or Zulu.2 in the airbus
Did your friend in the A320 use a GA to Airbus XLR adapter?
I fly the A320 too and am considering either getting the Bose A20 or Lightspeed Zulu.2 with LEMO plug and using a LEMO to XLR adapter from Marv Golden. That makes it neater (1 cable instead of 2).
Anybody out there tried this yet?

Bose A20
Hello everyone, I have a question about the Bose A20.
I understand that the bluetooth version has a high impedance mic and the non-bluetooth has a low impedance mic. Therefore I'm under the impression that the non-bluetooth version would work in China. Does anyone know this for sure? Are the plugs different in China?

HA HA thats funny
depends on the aircraft, I fly in the UK but on H300 which has the US U174 plug ( aka Nato ) which has the high imp. some of the other aircraft that I work on, has the same plug but is low Imp. so its not country specific but aircraft specific. what are you flying in china ?

It's not me flying them but a friend so I'm looking into it for him.
AS332 is what he'll be flying. With potential for the EC155.

As pointed out, it is irrelevant where the a/c are located in the world. You need to determine what the specific a/c uses, high/low impedance, 6 pin/u174 plugs.
If it is a low impedance system then order the non-blue tooth headset, with either a 6pin or U174 plug.

If my memory serves me right. the EC155 is a low Imp system but will check it tomorrow on the headsets we have, the plug however is a standard U174 Helicopter plug. I dont know about the 332 ??

You can not say just because you have a 155 that is low impedance, that all 155s' are such. It depends on vendors/customers requirements/requests.
The only way to be sure you get the right impedance is to check the specific a/c you intend to use the headset in.

duly noted Outwest, I have however been intimate with quite a few EC155's and AS365's all over the world and I have yet to find one with a High Imp system in them.
but if you can show me otherwise I will be happy to be proven wrong, you live you learn you know

I should mention that this company was a low impedance company for many, many years. Whenever a new type came online regardless of what it came with from the factory, it was converted to low. This changed when the S76C+ was introduced. All 76 A, A+, A++'s low, C+, C++ high.
The company finally started to switch over to high impedance on most types (139 for example). However, this is not a hard and fast rule, as I'm told by a friend who is on a brand new 225 that it is low impedance. This caused a bit of a problem both logistically and financially as pilots who might fly 2 types needed to carry both mics for a Bose, or use a DC that had a conversion switch.

The better option seems to be a low impedance mic with a low->high converter, but different aircraft react differently. Converters can cause issues with VOX, for example (e.g. line held constantly open, etc).
There are plenty of suppliers around the 'net who stock this sort of thing; plug 'aircraft impedance converter' into your favourite search engine.
