DC super reliable
There is what looks like a good pair of DC 10-40s on Ebay ending tomorrow (and more later, of course). The vendor recommends fitting new gel ear seals, and that is the set and combination I've used for nearly 30 years. Yes, the DC does clamp a little, but with gel seals it helps (and helps seal out noise if you wear glasses). Best thing about DC is total reliability. My fourpennorth.....
