Amazon Fire TV Cube review: Is Alexa worth the premium?
Product image · Source
"The fastest Fire TV yet," says The Verge, but critics question its value and Alexa reliability.
What reviewers loved
- Hands-free Alexa works without touching the remote, a capability PCMag says distinguishes the Cube from other media streamers.
- Fast navigation and app loading make daily use feel responsive; CNET launched Netflix and Disney Plus in just over two seconds.
- Broad app and HDR support covers major streaming services plus Dolby Vision, HDR10, HDR10+ and HLG.
- The HDMI input can route a cable box or console through the Cube and display Alexa weather or camera overlays on screen.
- The fabric-covered design looks more polished than the previous glossy model, while USB-A and built-in Ethernet reduce adapter clutter.
What held it back
- At roughly $140, it costs about twice as much as the Fire TV Stick 4K Max without delivering a similarly large picture or sound upgrade.
- CNET found Alexa unreliable and equipment control frustrating to configure, particularly because compatibility varies by TV manufacturer.
- What Hi-Fi? reported colours that lack punch and sound it described as lifeless, despite the Cube's premium position.
- The Fire TV interface remains Amazon-centric and ad-heavy, while PCMag notes that it lacks Apple AirPlay and Google Cast.

The short version
Critics report that the third-generation Fire TV Cube is fast, app-rich and unusually capable, with hands-free Alexa, Wi-Fi 6E and an HDMI input for connected equipment. The trade-off is hard to ignore. It costs around $140, Alexa and equipment control can be unreliable, and What Hi-Fi? found little picture or sound improvement over the much cheaper Fire TV Stick 4K Max.
What reviewers say about the Amazon Fire TV Cube (3rd Generation)
The Verge calls this Amazon's fastest and most capable streamer, praising its extensive hands-free controls, updated connectivity and HDMI input. PCMag reaches a similarly positive conclusion and gives particular weight to Alexa working without a remote, calling the Cube unique among media streamers.
CNET agrees that navigation is snappy and playback looks strong, but says Alexa becomes frustrating when equipment control fails. What Hi-Fi? is more critical of the fundamentals, finding the image crisp but uninspiring and the sound lifeless. Across the reviews, the shared concern is value: the Cube offers more features than Amazon's sticks, but the picture and sound improvement does not clearly justify the large price gap.
Best settings for the Amazon Fire TV Cube (3rd Generation)
The cited reviews do not include a Cube-specific calibration guide. Picture calibration belongs to the connected TV, and the linked RTINGS guide applies only to Amazon's Fire TV 4-Series television. For fully calibrated values, see RTINGS.

Buy it if hands-free Alexa, fast streaming and control of connected home-theater equipment matter more to you than getting the lowest price.
Skip it if you mainly need straightforward 4K streaming, want AirPlay or Google Cast, or expect premium picture and sound gains for the extra money.
Also consider
Amazon Fire TV Stick 4K Max
The obvious cheaper alternative. Reviewers say the Cube is faster and more capable, but What Hi-Fi? found its picture and sound were not much better than this roughly half-price sibling.
Apple TV 4K
What Hi-Fi? identifies it as the nearest streaming-box rival at a similar price, with double the Cube's storage and RAM.
Chromecast with Google TV 4K
PCMag notes that it costs far less. The Cube's main justification is its unique hands-free Alexa functionality.
Should you buy the Amazon Fire TV Cube (3rd Generation)?
The Amazon Fire TV Cube makes sense for a specific buyer: someone already invested in Alexa who wants a fast streamer, voice control without a remote and an HDMI input for integrating other equipment. For ordinary 4K streaming, critics report that cheaper devices provide much of the same experience. Its ads, inconsistent equipment control and modest picture and sound advantage weaken the value case.
