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 !

Update: Reduced rating from 2-star to 1-star because I will be returning this third Fire TV Cube Gen 3 for the exact same reasons I returned the previous two, except now I can add "vanishing menus, frequent disconnect from remote control, and repeated disconnect of 3 different bluetooth headphones/earbuds" to the list of problems. Most importantly, the problems with Ring announcement settings continue to reset back to being on, and we continue to be woken up in the middle of the night to maximum volume announcements of "MOTION DETECTED IN DRIVEWAY/FRONT DOOR!!!" My wife, who is highly technical herself and actually works for Amazon as a Principle Security Engineer, is really annoyed with me for continuing to try to get this working when this device (or at least a recent update) is clearly defective. As a replacement for the Fire TV Cube Gen 3, tried the Onn 4k Plus Streaming Device (GoogleTV) as well as the Google 4k TV Streamer (also GoogleTV). Both of these performed better than the Fire TV Cube Gen 3, but unfortunately, both of these devices had other show-stopping issues that made them simply not a solution I was willing to go with on my primary TV. I am actually appalled at the current state of the latest streaming devices. So, my solution was to go back to what I had (and was very satisfied with) -- the Fire TV Cube Gen 1. This bumped my various Fire TV devices around again (FireTV 4K Max Stick, FireTV 4K Stick, etc.), but guess what? They all work great. I just don't know what I'm going to do when Amazon forces this new OS on all these devices, because I'm sure it's going to mess them up as well, and then I have no idea what streaming device I will use. Maybe go back to Roku? ============================== I'm not going to discuss the specs or capabilities -- it's actually a top-of-the-line streaming device (or at least it should be). Unfortunately, I'm on my 3rd unit in 3 months. They keep locking up, stuttering, buffering, failing to load apps, and no matter what I do and how many times I turn it off in multiple locations in Alexa, Ring, and Fire TV, my Ring doorbell and Ring Camera keep reconnecting with the Fire TV Cube Gen 3, which results in the Fire TV Cube Gen 3 literally SCREAMING in the middle of the night (when a lizard, frog, or baby opossum crosses the driveway) "MOTION DETECTED IN YOUR DRIVEWAY" or "MOTION DETECTED AT YOUR FRONT DOOR". I even have the volume on the built-in Alexa turned down to zero, and it keeps resetting to full volume. I suspect this happens because I frequently have to reboot the Fire TV Cube Gen 3 because it locks up multiple times per day. And that's usually by unplugging the power adapter and plugging it back in because the reset feature in the Fire TV Cube Gen 3 menus will lock it up, too! On all three of these Fire TV Cube Gen 3 devices I have only had the usual streaming services apps -- Netflix, HBOMAX, Disney+, YouTube, YouTube TV, Prime Video (even AMAZON Prime Video locks up this AMAZON device!), ESPN, etc. Still locks up multiple times per day, usually when simply trying to load one of these apps to watch a movie. The third unit I received does seem to be doing a little better than the previous two, but if this one starts acting up the same way as the other two, my next return will not be an exchange -- it will be for a refund, and I will simply move on to something else like the Onn 4K Pro or Google 4k TV Streamer. Like the title of this review says -- I LOVE my Fire TV Cube Gen 1! The only reason I bought the Gen 3 was because it was on Black Friday sale and I needed another Fire TV device and didn't want to go with a Stick. The only Fire TV Cube model available now is the Gen 3, so that's what I had to buy. Amazon product support was zero help, and in fact became frustrated and gave up long before I did. All they ended up concluding was that it will likely be corrected in a future system update. So, until then I just have tolerate a $140 device locking up multiple times per day? Honestly, giving the Fire TV Cube Gen 3 a two-star review is generous.
