Fire TV Cube is the box for people who still pay for cable or satellite. Amazon calls it the only Fire TV streaming player with a built-in HDMI input: plug a supported cable or satellite box into it and you can change live TV channels by voice through Alexa or the included Alexa Voice Remote Enhanced. Built-in microphones and a speaker make it hands-free from across the room. Amazon lists an octa-core processor, 2GB of memory, 16GB of storage, Wi-Fi 6E tri-band, a 10/100 Ethernet port and a USB-A 2.0 port, with 4K, Dolby Vision, HDR and Dolby Atmos support. For Netflix and YouTube it does what the Fire TV Stick 4K Max does with a faster processor and a wired connection. Its limits are that the cable box control works only with select providers, the Ethernet port is not gigabit, and Amazon's US page did not show a price from our location, so its price is pending. For cord cutters, the stick or a Roku is the simpler buy.
Who it is for
Cable or satellite subscribers who want to control their set-top box and TV by voice.
