Author Topic: Recommendations sought: noise-cancelling headphones with boom mic  (Read 2118 times)

I currently use a Heil Pro Set Quiet Phone mobile, and the noise-cancelling headphones work very well, but the RFI into the received audio with the noise-cancelling circuitry active is very annoying (and apparently the bane of this particular product).

Does anyone have any suggested replacement product?  Particularly if you use it mobile at HF.  It would seem that noise-cancelling headphones are relatively easy to come by, but add the boom mic and not much left to choose from. 

Thanks,

RFI? If you're talking about the quality of the receive audio not being up to par, you're probably correct. After all, the circuitry is very similar to the way noise blankers work. As a result, the more outside noise you're trying to mask, the more the audio suffers.

By the way, covering both ears while in the driver's seat is verboten in all but a few jurisdictions.

Try a ferrite near the end that plugs into the radio, at three turns and the bead.  That helps at home for anything plugging into the radio like speakers and headphones.
