What we like
- Fastest Fire TV hardware, with an octa-core chip
- Hands-free Alexa — no remote needed for basic control
- Ethernet, USB-A and an HDMI input for a cable/satellite box
- Wi-Fi 6E
- Dolby Vision and Dolby Atmos
What gives us pause
- Costs significantly more than the 4K Max stick
- The same ad-heavy Fire OS interface
- Far-field mics need placement away from the TV speakers
- Large compared to a hidden stick
Who it's for
Households already living with Alexa who want to control the TV by voice — power, volume, inputs, playback — without hunting for the remote. Also cord-cutters keeping one cable box, since the HDMI input merges it into the Fire TV interface.
Hands-free Alexa
Eight microphones listen for 'Alexa' and handle power, volume, playback and app launching. Owner reports describe reliable pickup from across a living room with the TV at moderate volume. A physical mute switch disables the mics when you want privacy.
Ports and the HDMI input
The Cube's HDMI input lets a cable box or game console live inside the Fire TV interface — switch by voice. Ethernet and USB-A round out a port selection no stick matches.
Performance
Identical speed to the 4K Max in app launching and navigation, which is to say: instant. The octa-core chip exists mostly for the always-listening voice processing and video upscaling rather than menu speed.
Who should skip it
If you'll use the remote anyway, buy the Fire TV Stick 4K Max and pocket the difference. The Cube's premium is entirely about the microphones and ports.
