Yes, it is. I just purchased a 50-inch Insignia Fire TV and the soundbar works perfectly with it. A cool part about it, in my opinion, you don't have to use the volume control on your TV. Just connect the soundbar, turn the TV volume down to zero, and adjust your soundbar volume. It extends the life of your TV speakers in the long run; Plus, the soundbar is conveniently loud, so you don't have to turn it all the way up to get the desirable sound quality you want.
