All Sigtronics headsets and intercoms are specifically designed for high-noise environments and are RFI and EMI immune, giving you clear, interference-free transmission even in fabric or composite aircraft or in use with handheld radios.
The S-20 doesn't compromise quality and we don't expect you to either with one of the lightest and quietest headsets in existence. The S-20 incorporates the M-80 microphone, designed specifically for use in high noise environments with its excellent noise canceling properties. The microphone gain is set to operate over a wider range of aircraft radios, even handheld - the ultimate test.
These are marked as an entry level headset and I agree. I bought mine over 20 years ago (TWENTY!) as my first student headset. It's still going strong as my passenger/backup headset. I would also agree that the foam ear pads are uncomfortable, but for $144, you can afford to buy some gel pads for it. As far as needing a wrench to adjust it, if you tighten down the nuts only slightly, you can still make adjustments without using any tools. A great headset for the broke student or just to have a second headset around for the occasional passenger!
Compact headset, seems pretty durable foam ear muffs poor- too firm, not deep enough mic clumsy and doesn't come out quite far enough headband requires wrench to loosen/ tighten adjustment screws- not convenient, but OK once set.
