Hey All,

Im trying to hack my QC35 so i can use them in the plane, C172M, and save $700.

I just bought the Bose QC35
and an aux to 6.35mm converter and a single plug to GA.

Problems
1. I have audio in one ear only
2. The mic is compatible with the head phones and works, but i cannot get it to work when i plug it into plane radio.

Anyone have any ideas on how to make it work? what am i doing wrong?

Thanks!

I am not familiar with the QC35 but the fitted 3.5mm plug with 3 'rings' and a tip connection (left and right audio plus mic plus ground) will be connected to the 3.5mm stereo socket (I assume) to 1/4" stereo jack adaptor.. The adaptor is one connection short.
A probe around with an ohm meter will reveal the problem.
I assume that the 1/4" socket is a '4 pole' type, so it looks as if the adaptor needs to be swapped for a 4 pole type. I have just had a quick trawl around but cannot find anything. If all else fails you may have to cut off the 1/4" socket and fit a 3.5mm 4 pole socket, which would be neater and more reliable anyway.

OR cut off the QC35 jack and fit a beefy 1/4" 4 pole jack, but I assume that you may want to keep the cans standard.

The aircraft jack is mono, the Bose has a stereo plug. With this set up only one ear will work.

You could try connecting the Bose ear cups in parallel. This would affect the impedance but should be OK

There is a reason UFlyMike charges almost 300 USD for the conversion pack of the Bose QC to an aviation headset. Ain't advisable to tinker with pure adaptors ... Impedance matching for these environments is not a trivial task and be absolutely sure you know what you do! Wrecking Intercom and/or the Audiopanel is much more expensive than a professional solution.

Don't be a cheapskate. Buy a headset for aviation. You only have your hearing once! We are issued with Bose A20 at work because they are plug and play and the quality is exceptional. They are a buy once for life type of product. Although ironically I do seem to have an ever expanding collection of them as I have an original Bose X then I bought my own A20s and then work issued them.....

Apologies- I was forgetting that the standard cans are mono, of course. The above 3 posts are 100%.
