Amazon uses the term "Fire TV" to describe a lot of different devices but the one thing they all have in common is that they let you stream movies, TV shows, and more. Here's a rundown of the major Fire TV products: Fire TV streaming devices: These include the Fire TV Stick, Fire TV Stick Lite, Fire TV Stick 4K, Fire TV Stick 4K Max, and the Fire TV Cube. These products connect to your existing TV and give you access to popular streaming services through the Fire TV interface. Most models also include an Alexa-enabled remote with voice controls. Fire TV smart TVs: Amazon's Fire TV Edition displays are televisions that already have the Fire TV system built-in. You don't need a standalone Fire TV stick or cube — you just need to turn on the TV to find your streaming channels. You can find Fire TV smart TVs in lots of different screen sizes, and some even offer 4K UHD screen quality. They almost all come with an Alexa-enabled remote for voice controls. If you already have a 4K TV, we think the Fire TV Stick 4K Max is the best option of the bunch. It's worth the extra money for its higher resolution playback and snappier navigation speed. If you think you might buy a new 4K TV at some point, check out the Amazon Fire TV 50" Omni Series, which offers full 4K streaming. Meanwhile, if you don't already own an Alexa-enabled smart speaker, the Fire TV Cube is a versatile option since it includes hands-free Alexa support, just like an Echo Dot, in addition to powerful 4K media streaming.
