Do our Airbus planes provide power through the XLR 5 headset jack? I'm looking for a new headset and it would be nice to not carry around batteries. I'm currently on Boeing but will probably end with Airbus in a few years.

On the 330 the answer is no. The fifth pin is unpowered.

The Telex 850 works on the 320 series. I don't think it's a very good headset tho. The DC ProX has much better ANC and sound quality. Worth dealing with batteries IMO.

The Airbus version of the DC ProX can run without batteries through the headset plug (if powered, but I thought they all were for the Airbusses). It still has the battery pack on it though so if you get one you can use the ANR regardless. On the 737 I'm getting a few trips out of a set of batteries so it's not a big hassle.

Don't forget the F/A's, they always have extra batteries.

The answer is no. Airbus does not power the ANR function, you'll need batteries. But headsets still work without batteries, but just as a regular style headset, the ANR part will be off.

Telex 850 ANR is definitely powered on A319/320/321 plug.

The telex 850 gets its power via the headset jack. It will work on any aircraft even a Cessna. Because that source is very low power it’s ANR is weak. The standard airbus jack has 5 pins. One pin is a dedicated power source that allows full ANR. That assumes however that your aircraft have power to the fifth pin. It’s a Airbus option. On the 330 for sure and sounds like the A320 series the pin is unpowered. Delta did not pay the extra 100 bucks for that option.

Thanks for the replies Airbussers
