Apple Earbud Impedance?

Anyone looked into using regular earbuds for aviation? I'm no EE or i'd figure out the impedance myself. But, the number of different earbuds out there make me want to try it. Yes, maybe with a hand mike....
 
I believe it is 4-8 ohms for any standard ear piece. Your aviation headset speakers are 300 or 600 ohms depending upon mono vs. stereo (600 ohms total load to the radio/intercom).

Do a search and you'll find what you are looking for. It has been done.
 
Thanks!

Appreciate the info. I'm going to check it out. Just looking for something comfortable beyond my Clarity's.
 
Homemade ANR

I use a Bose QC20 with a 1/8" to 1/4" adapter.
For a microphone I use an old Telex 750 headset.
The telex earpieces sit nicely on the QC20 earpieces
to hold them in place. Even if the battery dies the
headset still delivers audio.
I have used it in several different airplanes with no
impedance or volume issues.
Not really fancy looking or even high tech, but very
quiet and comfortable for several hour flights.
 
Connecting the mic

I love your earbud headset. Could you explain how you wire the microphone? I wear a helmet and could attach the mic to it. My Zulus are pretty bulky when wearing a helmet.
 
It's a tip-ring-sleeve connector for the mic:
tip = PTT (used if you have a handheld mic)
ring = mic bias/signal
sleeve = audio gnd.
