Most GoPro videos of extreme stunts are accompanied by the sound of rushing wind, the roar of an engine, or just straight-up screaming. But with Sena's new Bluetooth Audio Pack for the GoPro Hero 3, you can use a wireless mic to provide narration alongside whatever stunt you're attempting.
The $US100 add-on attaches to the back of a GoPro camera like its Wi-Fi or extended battery modules, letting you capture audio from a Bluetooth microphone inside a helmet, or even an earpiece like a Jawbone . Its own rechargeable battery is good for about three hours, and with a wireless range of almost 100m you can actually narrate from a safe distance from the GoPro camera and the action if you don't feel like risking your life and limb.
