While I can't give you a 100% accurate answer, I can tell you that Beats by Dr. Dre Beats Wirless and Beats Studio Wireless headphones use Bluetooth. From research I have found that the standard Kindle Fire does NOT have Bluetooth, thus, they won't work with it, but Kindle Fire HDs DO have Bluetooth. I do not have a Kindle Fire HD or Beats Wireless or Beats Studio Wireless, so I CANNOT guarentee that they will work with the Kindle Fire HD. Your best bet is to see if you can find a display headset of the Wireless Beats you are looking at getting at a retail store such as BestBuy, and try to pair the headphones to the Kindle.
