Why buy a Bose headset anyway? They are in my view incredibly overpriced; for instance the most expensive wireless, Bluetooth equipped stereo noise cancelling headphones they make for home use are about £320 including VAT. Add a bit for the wiring and plugs, plus a mike and boom and I can't see a real value price of much more than £450.
I have flown with DC headsets in my aircraft for 40+ years, they never break, work as advertised and if you need parts they are readily available. And I haven't gone deaf (yet).
Too many companies seem to think the aviation market is not price sensitive. Think of how many litres of avgas a couple of Bose cost you compared to DC's!
