Nothing to write home about, but I did not expect much. I am not very picky, as long as they don't rattle and the left and right channel have the same level, I am ok. It seemed that the right one is louder, but then I reversed them, and the sound in my right ear was louder again I guess, my left ear lost some of it. So, cannot confirm the right channel being louder, which is a common comment of Amazon comments. They are reasonably comfortable for my head/ears configuration. Some customers complained that charge level is not reported - it is reported on my Android 10 phone. After one hour of use it reported 90% left. Going to use them through a day. I hate blister-pack packaging, completely irresponsible in this day and age.
A certain retro/refurb company sells cheap wired headphones with orange pads - and other colors too - for $15 and a pair of foam pads for $6. Anyway, now you can buy cheap walkman-style headphones with orange pads for just $3.28. They probably sound bad, but look the part.
