I wouldn't go past DC for genuine reliability, ease of maintenance (if req'd) and robustness.
I have used and abused my DC 10-20's for the past 15 years operating in some of the harshest environments around. They never let me down.
My hearing is still sound and the headsets still work. Consider them essential tools of the trade. Tradesman don't buy flimsy flash gear, they buy stuff that is strong and works. Their business depends on it, your hearing does too.
DC 13.4's are quite comfortable and pretty light too.
I am still a bit wary about ANR. The really good units cost a fortune and it's another thing to fail. Personally, all I did was use ear plugs with the headset. Cheap and reliable. It took a week or so for the ears to get used to it. Wouldn't go back now.
If you are stuck in outback Oz or remote Africa you want a head set that doesn't need to be sent back to base for repair.
Bottom line. It's your hearing. Once it is gone, kiss that medical good bye.
