These hardy little buds can hang with you no matter how hard you push it. They're IP68 rated, which means they're totally dust and waterproof. You could even take them surfing because they can handle salt water. And whether you're running, lifting or hitting the BMX track, there's no chance of the TwistLock Powerhooks falling. So the buds are safe... and so are you! Just turn on Ambient Aware while you're out running to hear bikes or cars.
