We use Bose-X, as a replacement for the DCs we used to have in our helis.
From experience: The Bose-X is not nearly as robust as the DC. Mine is presently away for repair to the plug at the aircraft end of the pigtail, which fractured internally. Looking at the remains, there isn't much strength or size in the plastic material where mine broke.
I have been obliged to go back to using a DC for a couple of weeks. It is nowhere near as quiet and at the end of my 13 sectors my headache told me I definitely missed the Bose-X.
