Star Trek fans will love the new Onyx device, which is made by OnBeep. It’s essentially a Star Fleet communicator. It doesn’t look like one, but you attach the gadget to your chest just like the ones in the TV series. With the device, you can talk to people in your group by pressing a button on the communicator. The Onyx doesn’t actually contact people directly. The clothing-worn communicator uses Bluetooth to connect to your smartphone, which is essentially the base for the device. The Onyx sells for $99 and you can pre-order it now.
