What Is the Amazon Fire TV Cube?
The Amazon Fire TV Cube is a streaming device that plugs into your TV and delivers 4K Ultra HD content — including support for HDR formats like Dolby Vision and HDR10+ — from hundreds of streaming apps and services such as Netflix, Prime Video, Hulu, Disney+, Apple TV, and YouTube. FlixCar
Unlike plug-in sticks, the Cube resembles a compact black cube and combines Alexa voice control, streaming media playback, and smart home control in one device. FlixCar
Voice Control & Hands-Free Alexa
One of the Fire TV Cube’s standout features is its built-in Alexa smart assistant with far-field voice recognition. That means you can control your TV and compatible devices using only your voice — even from across the room — without needing to press buttons. Alexa can:
- Turn on your TV and start streaming content
- Play specific movies or shows
- Adjust volume or mute
- Control playback (play, pause, rewind)
- Manage smart home devices like lights and thermostats
- Provide weather, news, and more FlixCar
This functionality makes it a hands-free entertainment hub and Alexa smart home controller in one device. FlixCar
Streaming & Picture Quality
4K HDR Support

Dolby Atmos & Audio
Audio formats such as Dolby Atmos are supported, bringing immersive sound when connected to compatible sound systems. Developer Portal Master
This makes movies, sports, and TV shows look and sound richer, provided your TV and audio setup support these technologies.
Performance & Connectivity
The Fire TV Cube features a powerful processor (often octa-core in newer versions) — helping reduce buffering time, speed up navigation, and improve app responsiveness compared with many stick-based streaming devices. TechBloat

Built-In Alexa Speaker & Mic Array
The Cube has built-in microphones and speaker hardware that lets Alexa hear you even when the TV is off — so you can get weather updates, play music, and issue commands without needing a separate Alexa speaker. FlixCar
Smart Home Control
Beyond streaming, the Fire TV Cube integrates with your smart home. You can ask Alexa to:
- Adjust lighting
- Control smart plugs and switches
- Change thermostat settings
- Manage compatible devices connected to your home network iptvtrends.net
