Mine fit several different people comfortably, and seem well-made, although only a few weeks' experience isn't much of a test.

I'd prefer to see a different plug-end (they have a single plug in line with the cord, and a double plug at right angle to it). The set is shipped with a splitter to share extra components.

Performance is quite good. On an old 727-200 without secondary sound source, if ambient flight noise is 10, the PQ's reduce it to about 6 without powering up and to 3 with power on, same effect in rows 5 and 19. Adding an MP3 or CD player, or plugging into the aircraft system would seem to virtually eliminate wind & engine noise.

Conversation may require adjusting an ear cup, but I prefer to sleep or read. That's why I bought a pair for my wife

Bose owners surely have equal or better performance, but they also paid about $300/pair.
