Amazon Fire TV Cube Review

Amazon’s Fire TV Cube is the first integrated hands-free streaming media device on the market, giving you the ability to use Alexa voice commands to control your entertainment center.

It’s essentially a Fire TV streaming device with a built-in Echo. However, at launch, its Echo functionalities are limited as Alexa Calling & Messaging, multi-room music, and Bluetooth connections to mobile phones are not currently supported. We hope these functionalities are added in the future as Amazon is pretty good about adding additional support for their devices via firmware updates.

So why do you need the Fire TV Cube if you already have an Echo and Fire TV? The Fire TV Cube also included an IR blaster, which means you can control your older AV devices, TVs and DVD players, basically any major brand electronics that utilizes IR remotes. It makes your home theater setup smart without investing in newer connected entertainment center electronics! While you may miss the latest technology on a network capable receiver or smart TVs, you won’t miss upgrading to the latest entertainment setup, yet. The Fire TV Cube is an excellent alternative to make your home theater setup connected.

Real world testing
The concept of Fire TV plus Echo in one device with an IR blaster is amazing. In our testing, it does most of the advertised functionalities. However, there are plenty of bugs to be worked out. We’re hoping future firmware updates can make it a more capable voice command streamer. Some of the issues we’ve encountered include no voice support for Sling TV other than launching the app, not able to turn LG Smart TV on every time, it will always turn on the receiver when you go home on Fire TV even though we set the control to manual instead of automatic, it can only change the volume of TV or receiver/soundbar but not both depending on your setting, and the biggest complaint is that the video freezes while waiting for Alexa command.

Even with these misses, the Fire TV Cube is extremely responsive and useful. It’s a luxury to be able to turn an older receiver on and off and change the volume by using Alexa. Netflix and Amazon Video integration is fantastic. You’re able to launch specific shows or movies by voice easily.

From time to time, the Cube will say it can’t find a device named TV when you’re using voice commands. Multiple people have reported that it works sometimes and all of sudden it’ll stop working, only to work again few days later. The work-around is to set routines in the Alexa app where you can say TV off to turn off your TV. Again, we hope Amazon works out these kind of annoying bugs that makes the Cube voice command experience usable but frustrating.

Connection issues
As with any network device, you may encounter wi-fi and connection issues regardless of your internet speed. Any connected device needs an IP address that does not conflict with another device’s IP on the same network. The best way to make sure your Fire TV device has its own dedicated address is to manually set it. Go to Settings -> Network and select the manual setup option. Enter an internal IP address that does not conflict with your other devices. Find out what your gateway address is and enter it into the configuration. Lastly, you need to enter in DNS server information by using Quad9’s free DNS service.

New remote update
In October 2018, Amazon released a new Fire TV remote with volume buttons. Unfortunately, the new remote did not make it in time for the original cube release. Bummer. However, it’s included in the cube re-release. Previous owners can also purchase the new remote for 50% off at $14.99.

Multi-room music & follow-up mode features
On December 12, 2018, Amazon added multi-room music and follow-up mode feature to Fire TV Cube devices.

Calling, voice messaging and the Drop In features
On May 30, 2019, Amazon added more Alexa features to the Fire TV Cube. You can now be able to call, send voice messages and Drop In on other Alexa devices straight from your Fire TV Cube.
