This is an adapter that will send receive BT audio sent by your phone/tablet/computer/etc to anything you connect to its 3.5mm jack: headphones, the aux input jack in your car or home stereo receiver. These should work with Fire TV as BT headphones. Sound quality is decent (BT 3.0). Has a built-in mic for return audio, but the one I opened and tried was so bad that it is unusable.
The price for these is all over between stores in my area – from 50 cents to $1, $4, $6.75+, so this is a very YMMV deal but seems to be widely discounted and on it’s way to clearance in most stores. I paid $1 for several yesterday, they’re down to 50 cents today.
Various colors available and two different case designs, but all appear to share same SKU and UPC. Happy hunting.
