Fire TV Cube, with AI-powered Fire TV Search, Hands-free streaming device, find shows faster with Alexa+, Wi-Fi 6E, 4K Ultra HD

I wish I’d know about this sooner! I’ve always had Firesticks on all my TVs and a Dot in my room. This does both with double the storage and is sooo fast! Stable connection, voice reasonsivness is amazing, and ease to use. I have the Firesticks on all my less used TVs still but this is a must have for popular rooms in the house where I use Alexa for everything. Luna gaming works so well on this too, definitely worth the upgrade!

I’ve been a loyal Fire Stick user for years, but I finally hit a breaking point with the constant lag and "loading" wheels. I decided to splurge on the Cube during a sale, and after two weeks of heavy use, I can honestly say I should have done this a long time ago. The Speed is Real: If you’re coming from a Stick, the first thing you’ll notice is how snappy it is. Apps like Netflix and Disney+ open almost instantly. There’s no stuttering when scrolling through the home screen, which used to drive me crazy. It feels more like a high-end gaming console than a little streaming box. Hands-Free Alexa (The "Magic" Factor): This is the feature I thought I wouldn't use, but now I’m hooked. Being able to walk into the living room with a bowl of popcorn and just say, "Alexa, play The Bear on Hulu" without hunting for the remote is a game-changer. It even turns my TV and soundbar on for me. It basically turned my living room into a hands-free Echo Show. Pros: • The Processor: Zero lag. Period. It handles 4K content like it’s nothing. • Connectivity: It has an Ethernet port and an extra HDMI-in port. I actually plugged my cable box into it so I can switch to live TV just by asking Alexa. • Wi-Fi 6E: My router is in the other room, but the connection has been rock solid with no buffering. Cons (The "Real Talk"): • The Price: It’s definitely an investment. If you only watch TV for an hour a week, it’s probably overkill. • No HDMI Cable: For this price, Amazon really should include an HDMI cable in the box. Make sure you have a spare 4K-rated one ready to go. • The Ads: Like all Fire TV products, the home screen is still pretty cluttered with sponsored content/ads. You get used to it, but it’s there. If you’re a "power user" who hates waiting for apps to load, or if you just want to control your entire home theater with your voice, this is the best device Amazon makes. It’s powerful, smart, and actually makes the TV experience feel "premium."

Update 11/12/25: So after having written the below review I decided I should give an update to the issues below. I've had other streaming devices since then and I have to admit that the fire tv cube beats them all. Reasons: The" best available" setting is actually the best setting. What it does is that ot converts DD+ sound to Multichannel pcm which is a lossless and uncompressed quality and passes it to the AVR. The AVR will show Multichannel 5.1 . It is the best sound you can get. I came to this conclusion after months of testing and research. Roku ultra has passthrough but it just passes the compressed format DD+ to the AVR so the AVR displays DD+. The TV turning off big is fixed. 10/4/23 update: Now another bug has appeared. When I watch on my LG C3 OLED TV the TV turns off automatically after a while. Sound continues but no picture. I initially thought it was my tv. Got another unit ,same TV, and the same issue happened. Then I decided to watch ony Roku ultra and have not had any problems so far. Tried the cube again 2 days ago and issue returned. I even turned off equipment control and reset the cube but didn't work. So now I'm not using it. It's just sitting there looking pretty. 7/23/23: Just to update that the video issue has been fixed. The audio issue not so. 11/23/22: Still no fix. Reverts to 1080p despite setting to Auto. Now noticing jitter or stutter on video when playing 4k content. Changed settings of Match frame rate to on but didn't resolve issue. Constantly checking display settings. Given up and using my other streaming device with no issues. Did not expect this from Amazon. 11/15/22: So since purchasing this there have been a number of updates installed but NONE have fixed the issue of sound and display settings as mentioned in my previous updates. This is truly disappointing and makes me want to use this device less often than I would like to. 11/9/22: Still issue with display resolution defaulting to 1080p. Always have to check before playing something. No fix. Not acceptable for a "high-end device" Update 10/29/22: Still no luck on best available sound settings outputting DD+. But now another issue. Whenever I awaken the cube the display resolution defaults to 1080p even though I set it to Auto(up to 4K). It's frustrating to have to change this every time I want to watch something. So many bugs! I've had many fire tv sticks over the years and also a 2nd Gen cube which I returned because it wouldn't play Dolby vision. Thought I'd give this a try since all the upgrades were compelling. Faster, built-in Ethernet port, HDMI in, supporting all sound and picture formats. So I set it up withy TCL tv and Sony receiver . Setup was a breeze. It recognized my TV and receiver. For some reason the picture quality in display settings was defaulted to 1080p. I changed it to upto 4K. Sound settings were "best available ". When I played content it would only play in PCM (stereo). I tried Dolby digital and Dolby Atmos content. Dolby Atmos would play as Atmos +PCM, not Atmos +DD+ as it should. I checked ally settings on the TV and receiver and all was good but couldn't get DD+. Called tech support and was told that it may be a software issue and may get fixed in a future update. Really??. All the hype about how this device is the fastest and best on picture and sound yet it can't output "best available" sound. I'm sure best available is not PCM. Tech told me to set the sound settings to Dolby digital plus. That corrected the issue but it was a let down. I'm hoping it doesn't revert back to PCM. Will see how it goes and update but so far disappointed. The super resolution setting really doesn't add much to enhance the picture quality of SD or even 720 or 1080p resolution. And that was one of the main features that enticed me to buy it. Update 7/2/23: The video resolution issue is now fixed but the audio issue still persists.

Overall the ux is good and navigation performance is snappy. The cube was not able to set the Antenna input of my Hisense TV, (although it could set HDMI for the Firetv cube input, and OTA channels once it was manually set to Antenna using the TV's remote). So I ordered a Tablo 4th gen to see if that will allow only needing the single Fire Cube remote for OTA channels and the rest of the fire cube stuff. Voice control works ok, but struggles if there is background noise. Asking Alexa for current weather as a skill to my weather station is good, but it does not mute the tv programming audio and so that competes with the weather report. The cube's built in speaker is loud enough for me, and very useful when audio response is needed while TV is turned off. I wish the remote's volume control buttons could control the cube speaker when Alexa is talking through it, but it does not. But overall I'd recommend the cube 3 over stick or Roku options, to eliminate lagging/freezing issues in those other devices, especially if the Alexa integration is desired.

We loved the 1st gen and hadn’t had the change to upgrade until recently. I love all the new features. It’s so easy to set up everything too. I was having issues with connecting it to allow the alexa to turn on/off the tv and volume control on the soundbar. After checking reddit, the issues were resolved. So far so good! This was also much more responsive compared to my old gen.

I just bought this product. Easy to install and the picture quality is wonderful. However, I can't get the sound to work for Alexa, the cube doesn't respond to any commands and doesn't talk to you. Both my LG TV and this version of the new Fire Box are brand new. It may be my issue and I haven't figured it out yet. Moving into a new home is hard enough, then to try and find time for the items you purchased to make your home amazing takes time. I started ordering last year since it took a year for this house to be built. I won't order things a year in advance anymore. New versions have come out and they are the same price or a little more. I'd rather have the latest version. I have other Alexa devices at home, so I am not worried about that part not working. The remote is great and easy to use, and I normally don't ask my TV to turn the channel...lol. I used to use foil on the antenna so I could get a fuzzy picture or a coat hanger so my brother and I could watch Batman as kids. It will get a higher rating if I figure this sound issue out. However, right now it is worth the price just for the picture quality. WOW, an Amazon Rep. phoned me and fixed my issue. She was wonderful and fixed the issue which was my own fault. It took about 5 minutes, and it was talking up a storm. Update: This cube has caused a lot of issues. I gave my old cube away to my sister, so I am SOL. This cube got so hot on so many occasions that it burned the top of my dresser. It freezes and will not work. It doesn't connect to my new Echo or old Echo devices. Tech support told me that it was because "I didn't buy them together!" So, I now use my Yamaha soundbar. I don't even like to call foreigners anymore. Please bring back the English-speaking techs and operators, it is so frustrating that I hang up and just deal with the fact I bought an expensive POS. I even wrote to Amazon and nothing, left my phone number, and asked for a return call. I bought a bunch of Echos for this new house and haven't even taken them out of the box. Nothing is pairing with the TV, Echo shows, or Echos. They do not support each other. I also have the Eero 6 Pro system in my house and the new Echo won't even connect to that. I'm terribly upset and the resolutions the tech team talks about are ridiculous.

Hands down one of the best Streamers on the market ! Quick and easy to use,... picture is awesome,...system is very responsive. The only fault I can find is the continuity of stream (buffering) when used with WIFI,... and that may be the fault of my system/provider. On Ethernet cable,... the stream is steady and reliable with no buffering. Picture is 4k awesome and even up-scaled content is great ! Not a fan of voice control,...so I don't use Alexa. The only other negative I found was the smaller size of the controller. I have big hands and arthritis,... so the smaller buttons can sometimes big a challenge when "arthy" is visiting !

After several months of use, I thought this review needed an update. If it was possible to change my 1 star rating to zero stars, I would definitely do it. I keep hoping for software upgrades that would address some of the issues, but none have been forthcoming. I can't even get the upgrade that I know is currently out as the Cube says it is up to date. It isn't. Audio issues have gotten worse over time. When Surround is set to "Best Available", it is always Dolby MAT and only recognizes Atmos for Amazon content. Sound output on Dolby MAT is so low it is essentially unusable. The hype on the screen says it will provide the best format up to Dolby Mat, but that is just a lie. It provides Dolby MAT period. Similarly when set to Dolby Digital Plus it is always Dolby Digital Plus, and there is considerable delay before it recognizes Atmos, and often it doesn't recognize it at all unless I reboot the Cube. The issue with the HBO MAX app appears to have been resolved as I no longer have to restart the Cube every time I want sound on that app from the Cube. This really is a terrible product if audio matters to you at all. And audio does matter to me. And I still don't understand why Amazon won't at least give me the latest system software for the Cube. I know there are serious security issues with the version I am running (7.6.1.3) and I know 7.6.2.5 is out, but the Cube says it is up to date. Totally unacceptable service from Amazon. On top of that, the Alexa volume from the Cube's internal speaker is so low now that it is undetectable if my ear is more than a foot away from the device, though it's medium OK through the TV. Volume on the Cube is set to maximum. The microphone isn't sensitive enough to pick up a shout from more than 6 feet away, and a shout is required at any distance from the unit. External USB storage devices are pretty much limited to thumb drives. Have tried several hard drives (formatted correctly) and none are recognized by the Cube, and it takes a significant amount of time for it to recognize a thumb drive, but it eventually does. Though it would be a huge hassle to untangle all of my Amazon stuff, I'm seriously considering switching to Apple, because this product is just terrible and Amazon doesn't seem interested in fixing it. Pretty much all of the issues are audio related. Video is pretty much OK. Previous revue: Well, I've only had it two days and lots of issues. Not ready for prime time, but when it works, it's excellent. First, it was supposed to come linked to my Amazon account. Nope that didn't happen. Shuts down at random for no reason. Takes it quite a while to recognize a change in audio format leaving me with several seconds of moving lips with no sound at all. Alexa's volume is too low even at max when running through the built in speaker. Fine running through the TV. Audio outputs are also way low. Soundbar goes up to 100, but the cube needs 20 points more than the Firestick 4K it replaces. Still usable, but strange. Hard to say at this point if it's a hardware or software issue. HBO Max app is especially problematic as far as audio is concerned. Many settings are inadequately explained. Setup asked if I wanted to import from a previous version. I've had 4 Firestick Versions before this, but my only option was to import from my very first Firestick rather than my 4K. Only had it 2 days, and maybe software updates will fix it. I'll give it a couple more days to see if it settles down, but right now it's pretty wonky. This stuff should have been worked out before they shipped. Revised Reduced the star rating to 1 because the problems are inexcusable. After 3 days of troubleshooting, I think I may have resolved the issues. The issue of the cube randomly shutting down seems to have been resolved by unplugging the cube and plugging it back in. Other issues all involved my setting the audio to "Best Available". Changing to Dolby Digital Plus appears to have resolved the issues. In my case, the "Best Available" was Dolby MAT/Dolby Atmos Mat. The problems were several and intermittent. 1) Sometimes when adjusting the volume using the cube's remote cause the audio to go away altogether. Made no sense and was very difficult to receiver as it wasn't simply a matter of it muting the sound system, the cube wasn't actually putting out sound to the system at all. Randoom buttoon pushing was the only resolution. 2) With the audio set t "Best Available" the cube frequently did not recoognize when a Dolby Atmos prgram had started. This was intermittent. Sometimes it switched from Dolby MAT, to Dolby Atmos MAT and sometimes it didn't. A woork around was to start the program go to Settings, chose Display & Sounds Settings, Go down to the Audio & Video Diagnostics and click "Play Dolby Atmos and HDR Content." Then hit the back button repeatedly until you get back to the program and hit play. I am not making this up. 3) Once I got Dolby Atmos MAT enabled, it didn't go away when playing non-Atmos content. It did seem to play 5.1 OK while Atmos was enabled, but eventually it would bounce back to Dolby MAT, but this was also often problematic. When switching back, it went smooothly some of the time. Other times, it killed the audio altogether leaving me with the same issues as above. The other transition was even worse. The picture began flashing with the audio going on and off. The oonly work around I could find was really weird. I opened HULU and played any episode of Letterkenny. No other program oon any service including HULU worked reliably. I cannot explain this, but it is what happened. 3) the low volume issue was completely resolved with the switch to Dolby Digital+ as opposed to Best Available. Solution was indeed the change in Audio Settings from "Best Available" to "Dolby Digital+". With this setting so far, Dolby Atmos was recognized on all three of the services to which I subscribe that support it, and it dropped back to 5.1 or whatever other format was appropriate to the content. As I just foound this solution this morning I can't claim that all issues are permanently resolved, but at least the seem to be for the time being. The Alexa thing is still useless when it uses it's own speaker, but fine when it uses the sound system. But it appears I wasted 3 days of challenging troubleshoooting t fid a solution and I ain't happy. Amazon doesn't document much of anything, and the on screen info is limited and often confusing. It's inexcusable that Amazon would release a product that requires that much time and effort on the part of a user to unravel. Should have been caught and fixed in testing before it was released on unsuspecting consumers. I am seriously angry at having to do their job for them without the nice compensation they pay their engineers for.
