One of the features that makes Airpods so great compared to other Bluetooth devices on the mark is automatic ear detection. When you put the buds in your ear your computer's audio should begin to play through automatically. When you remove them; the audio should pause. But, if this isn't working for you, you'll need an iPhone to correct the problem. Automatic ear detection is a feature that can be turned on then off. Head over to your iPhone and tap on 'Bluetooth.' Then, tap the 'i' next to your Airpods toggle the switch on and repair to your computer.
