Any pilots in here?  I have a question about pilot headsets.

What kind of connection do they use?  Could I connect a set to a computer for use as a headset?

I ask because I have bought a couple computer headsets and they always die on me.  I checked into pilot headsets and there are some inexpensive ($160) student pilot headsets for sale, marketed for the beginning pilot.  If I could get it to work with my computer it would be great.

Thanks for your help!

There are two plugs: a 1/4" stereo (although most airplanes only have mono output) plug for the earphones and a 3/16 0.210" mono plug for the microphone.

This link is relevant to your interests.

ETA: Corrected mic plug diameter.

aviation headsets use a seperate plug for the mic and the headphones.  Normally the headphones have less than qulity sound, but its a tradeoff of durability. In all i would say that you should look into buying a seperate headset for flying than computer work.  I also recomend that if you plan on flying for a few years, that you get the best headset you can afford. A noice canceling headset saves your hearing, and they get more comfortable as they get more expensive.  I've got around 2k hours, and thats on 2 headsets. thats alot of time wearing something, glad i got a good one.

You will need an impedance matching circuit to "get er done".  If you are doing online FlightSim stuff just use those cheapass USB setups.  I used my SOCOM Navy seals Rig from my PlayStation and it gets the job done OK.

Aviation headsets are typically mono (unless explicitly purchased for stereo use), their impedance is 600 ohms.  The microphone is typically carbon, electret, or amplifyied dynamic and has an impedance of 150 ohms.

I wouldn't recommend buying aviation headsets for computer use escpecially if you are looking at those inexpensive ones.  The cheap aviation headsets are built just like anything that's cheap!

Plus the cheap ones will be mono and they have a frequency response tailored for voice only (300Hz-3KHz) so their overall fidelity isn't that great.
While the earphones would probably work with a computer, the mic probably will not work unless you get some sort of impedance matching network.
