i used this site to buil my very own noise cancleing head phones for probly about $20
they are awesome!
the headphones that i put in arnt the best but are still good
i am happy!!!
Did you find it on hackaday? I saw it too, and I have a spare mic (the type on the page) from a device I modded to take audio directly, so this might be a good opportunity for me.
that was too complicated for me and would be too expensive and a pain to carry that around when u can just do this for like $20 and they barley let any sound in
when i have no music playing i can hear my heart beating
and these are for my friend but i think im gonna make more for some people
