A:AnswerYes and no. I have the 4k fire tvstick as well as the regular firestick from last year and it doesnt seem to work with the regular firestick for some reason at all.However it will work with the 4k one but its alittle sensitive to it .It will cut out completely if u press the cancelling button and sometimes the middle button so be cautious because it get very hard to connect the headphones after that.
