Apple AirPods are sold separately for $159.00 through apple.com.
The iPhone XS Max does not ship with a pair of AirPods. Instead it ships with a pair of EarPods with Lightning Connector. These can be connected through the Lightning port on your device since the XS Max is not equipped with a 3.55mm headphone jack.
The iPhone XS Max also ships with a Lightning to USB Cable and 5W USB Power Adapter for charging your device.
