When using Airpods on an Android device (I am specifically using a Google Pixel 2), does sound come through both of the Airpods when making/receiving calls? Or, does only one of the Airpods play sound when on a call?
AirPods work like standard bluetooth headphones on non-Apple devices. You'll hear sound through both AirPods on calls.
I'd encourage you to visit your local Apple Store and do an in-store demo using your phone to see if they're right for you. Alternatively you can have them shipped to you and return them within 2 weeks if you aren't satisfied.
