I've tried DC, Sennheiser and BOSE products and there is nothing I've ever now use except a BOSE A20. I really want to be able to hear my grandchildren laughing in the garden one day so I'm not prepared to compromise.
There is a good reason the A20 is so common on B737 Flight decks the world over. It's a noisy place to work and even at the price, it's very good value.
