$20 ANC is gonna be difficult (or impossible), maybe a used pair?
I meant a bt adapter that can make wired headphones have ANC. I don't think I mentioned a low price though.
ah yeah i got confused. it would be physically impossible for a bluetooth adapter to make headphones perform as if they have hardware that they don't have. so i thought you were referring to the $20 headphones as having ANC.
here is a great explanation of how ANC works: https://electronics.howstuffworks.com/gadgets/audio-music/noise-canceling-headphone3.htm
but tldr is that you need a microphone on each ear and good circuitry to calculate the exact noise canceling frequencies to play.
