Regarding reliability: I have been using it for more than 5 years. I used it moderately (no more than half an hour a day on average). For the entire period of operation, no complaints, except for the rustling and knocking sound when gratering wires on clothes in winter. A couple of months ago, I damaged the shell (either the cat had a bite, or cut it somehow) on the wire of one of the headphones. The wire held on to the guts and worked great. Soldered today. Probably another 5 years is enough . The thickening on the wire in the photo is the place after soldering. I am not a picky listener. But, compared to several other headphones in the economy price segment, the sound is the best. The earplugs save enough from noise to listen to music on the subway and not turn the volume up to heaven.
