Flight test report
I flew my RV-7A with my new Halos and my new homemade headset for the first time. As many of you know, the RV cockpit is EXTREMELY loud--I have measured it at 95 db using a radio shack db meter. I have a Superior XP-360 engine.
Some observations:
1) My homemade headset works great! Overall noise attenuation is much better than the Bose X and my old Bose 1 headsets. Low frequency noise is attenuated quite well, perhaps a hair less than the Bose X. High frequency noise is attenuated MUCH BETTER than either Bose headset. So overall, my homemades come out way ahead.
2) XM radio sounds much clearer and richer.
3) The spruce mic seems to work just fine. I did a radio check with unicom and they said I sounded loud and clear.
4) The comfort factor is extremely high. It will be nice to wear a broad rimmed hat while flying.
5) For some reason I could not hear myself when speaking on the mic. Maybe that's a radio setting, I'm not sure.
6) The Halo headset sounds clearer and richer than my homemades. Voice is definitely clearer and xm music is fuller and clearer. Again, it's not that the Comply NR-10's don't sound good, they do. It's just that to my ears the Halos sound OUTSTANDING. Full disclosure: as with most normal adults I have some high frequency hearing loss, I have difficulty with anything above 10 kHz.
7) With the Halos, I could hear myself speaking.
8) Noise attenuation of both headsets is about the same. I cannot tell any difference.
9) The comfort of my homemades is equal to that of the Halos. No surprise there, since I fit them to my head!
So there you have it. Since the Halo headset sounds clearer to me, I will wear those. However, my homemades fit my wife perfectly, so she is very happy to wear them, rather than her Bose X.
With this homemade headset project, I will be able to sell both my Bose X and Bose 1 headset, reaping about $1000, not bad!
