Fire TV Cube
The Fire TV Cube is a near-cube that measures 3.0 by 3.4 by 3.4 inches (HWD), with sharp 90-degree edges between each face.
Hands-Free Alexa
You can treat the Cube like an Echo device, waking it up by saying "Alexa" and talking to it without touching the remote.
Ethernet Adapter
No Ethernet port is present on the device. Instead, you can plug the included Ethernet adapter into the micro USB port if you want to use a wired connection instead of the Cube's dual-band 802.11ac Wi-Fi.
Full Package
The Fire TV Cube includes a remote, Ethernet adapter, and IR blaster.
Top
The top panel has eight pinholes for the far-field microphone array, along with four buttons typical of most Echo devices: Volume Up/Down, Microphone Mute, and Alexa (for manually activating voice control without using the wake word).
Front
The front face features an etched Amazon logo and a translucent bar on the top edge that lights up blue when Alexa is listening.
Back
The back of the Cube holds a connector for the power adapter, a 3.5mm jack for the included infrared blaster, an HDMI output, and a micro USB port for service.
Bottom
The Cube sits on four very shallow rubber feet, lifting the device up just slightly so the downward-firing speaker on the bottom can be heard.
Remote
The included remote is identical to the Fire TV and Fire TV Stick remotes. It's a simple, narrow, 6-inch-long black plastic wand with a glossy circular navigation pad flanked by a microphone button above and six menu and playback control buttons below.
