I fly ATRs and I use ordinary DCs, I think the same you have mentioned.
They are fine.
A colleague, wearing a noise-cancelling set, completely missed an audible caution because his headset cancelled it out.
Perhaps you need something a bit more beefy in a twin-otter, tri-lander or a helicopter, but I can vouch for the performance of ordinary DC headsets in a turbo-prop.
So perhaps you should state what you are flying and go from there.
