I found the Bose A20 to press down on the pin ontop of my hats I wear. For this reason I bought the Sennheiser S1 as I was informed by a fellow pilot that this problem would be eliminated if I did so. So for me this headset is more comfortable, the sound quality and ANR in comparison to the A20 are equal and the price is cheaper. It is heavier than the A20, however the lightweight feature was what Bose focused on for their headset but this was never a problem for me. I did an 8 hour flight stra
I'd be inclined to question those who informed you of the 25 hour battery life regarding the Sennheiser. Certainly not the case for me, I'd easily have 35 hours up by now and they're still going strong. I use it daily and this was a feature I was sure to question when I purchased them. Bose A20 none the less is certainly a very nice headset and I do still use them aircraft and flight type dependant.
@coastalpacific You are correct about the FAA TSO program and they (FAA) do not mandate a TSO'd headset for any specific application. However, as far as we are aware, every US based regional and national airline has established rules requiring that employee headsets have an FAA TSO. Please let us know If you are aware of any US based carrier that does not have these policies.
Well one more thing I forgot to mention Bose Battery's last 35 hours according to manual but for me they have lasted 44 hours plus with pretty heavy use. the Sennheiser S1 battery power I believe lasts only 25 hours . I prefer something light when I am flying. R they TSO'ed ?
Not true. "...the FAA's TSO program with regard to headsets and microphones is for the purpose of establishing a standard, or benchmark for such equipment, but that the FAA has not mandated nor regulated the use of such equipment..."
Nope ! much heaver, than Bose A20 , hear when ANR is used the sounds tiny and artificial don't know if they are TSo'd nor can you switch the mike from left to right like in the A20 however certainly a very good looking headset with a great brand name
