Apple today showed off a set of wireless AirPods that connect to the iPhone and Apple Watch with a single tap. The AirPods can automatically witch from iPhone to Apple Watch based on what the owner is using. The AirPods provide up to 5 hours of battery life. The devices rely on the W1 — what Apple says is its first wireless chip. The pods include a battery, antenna, accelerometer, and proximity sensor. The case has a built-in battery, which can provide a total of 24 hours of play time. The AirPods will go on sale in October for $159
