You love your GoPro because it captures beautiful video, not necessarily beautiful audio. That’s why Sena released the Bluetooth Audio Pack; it connects seamlessly to the back of your GoPro to capture crisp audio while blocking out annoying wind noise. And, it can even connect to other friends’ Packs so you can capture full conversations (and screams of exhilaration) from the whole crew. Note: $129.00 with waterproof case.
