Input: I've used this unit for commercial trucking daily for a few months. Sound quality is excellent. All day-comfort is excellent. Volume tends to be a bit low for my environment but is still functional. My major beef is the poor physical construction. In particular, the swivel joint where the headband meets the earcup. It's of very poor quality. You have a tabbed metal post swiveling in a plastic bushing. After a short time of (what I consider normal use) being taken on and off, and taken in and out of bags, that joint broke - rendering my headphone useless. This headset is great for "light" use and delicate handling. If you're man-handling it in a commercial truck, it won't last.

Great Features, Comfortable, Not For Commercial Use
