After having several David Clarkes for years and getting great service from them with a small problem 5 years after I bought one of their headsets I bought their ANR... Whoops what a mistake. I can't stop it oscillating and making a sound like a motorboat. This goes if you press the earpiece against your head . Its been back to Headset Services and DC in the US and it comes back with the usual " it works perfectly now sir" Well lo and behold it doesn't.
I purchased a Bose ANR... brilliant and well worth paying the extra over the DC.
The problem is I use a DC helmet which only takes DC headsets.
So now I have to decide between the helmet with oscillations or silence. Have opted for the helmet as I fly aeros. I wonder if anyone else has had a similar experience.
The bottom line is DCs are very good ( both the product and after sales service) but if you want an ANR headset then make sure you try it out first... or you could just buy the Bose, you will not be disapointed.
