If you are a fan of Star Trek or push to talk - walkie-talkie style communication, you will definitely love this offering from Orion Labs, called Onyx, which is essentially a Star Trek-like walkie talkie communicator similar to the communicator badge Captain Picard uses on Star Trek.
Onyx is a real time communication device that allows you to talk to people in real time, as well as being able to talk to intelligent agents such as Amazon Alexa.

Onyx Star Trek-like walkie talkie communicator works with the Orion App (available on Android and iOS) on a smartphone, though the Orion app does not need to be open for it to work. This is great as it means, you can be doing other things on your smartphone like taking a phone call, streaming audio or playing a game.
The Onyx Star Trek-like walkie talkie communicator also features a TRRS 3.5 mm socket for plugging in a headset with an integrated microphone
If you don't want to hear the audio from someone else speaking, you can rotate the front of the Onyx to put it into Mute mode so everyone in your group is muted. To let others know they have been muted, the Orion App circles you in yellow to let everyone know they have been muted.
Another nifty feature that makes the Onyx a smart walkie talkie is the "Distance Location" feature that allows you to check the location and distance the people in your group are from you by simply clicking on their profile.
After successfully pairing your Onyx with your smartphone, the 5 light display on your Onyx will briefly blink. When the battery is low on the Onyx, one of the lights will blink red. The battery status of the Onyx is indicated by how many lights are lit up (each light indicates 20% charge). When all lights are solid white, Onyx is fully charged.
Using the Onyx is pretty straightforward. Simply turn the face clockwise until it vibrates and continue holding it until it plays a sound; then release. Next, download the Orion app, launch it and sign up by creating an account. The Orion app will walk you through the basics such as pairing with your Onyx, creating a group and sending messages.
