I have tried on 2 occasions to get these headphones to work. No luck. The "instructions" are pictures without explanation as to what they mean. The buttons on the headphones are black on black with tiny symbols that I can't te. You need a magnifying glass and hold the buttons at an angle to see the tiny, shiny black image against the matte black background. There's a connection cord with a USBC end and an ancient USB on the other end. Sure can't plug that into my computer since it's from this century. These were at an elevated price, so I expected something a little more modern. I tried the website, which gave a little more info, just not enough to get these to work for me. I don't give up on challenges easily, but my time and frustration level is making me consider returning these now, before I waste more time and energy.
At the fully closed head piece thing, they might still be too big for me. I haven't gotten that far to check.
On the plus side, I noticed an L and an R inside the ear cups. Also, I got a red light to come on. I hear they have great sound, maybe I'll find out someday, lol!
