Meet the AWIRE: a two-way radio you can wear to stay connected. It works with your smartphone, so you will be able to listen to music, answer calls, and communicate with others. You can control the settings from the companion app. It has a lightweight design and one touch operation.
The AWIRE lets you keep up with your crew from up to 2 miles away. It is compact and does not get in your way. You can find it on Kickstarter.
