AirPods are compatible with Apple devices such as iPhone, iPad or MacBook. If you think that you are partially correct, you could also connect your AirPods to your Chromebook.
Both AirPods and Chromebook go well with each other; both are compatible because both support Bluetooth. So, don't think you can only connect AirPods to Apple devices because, in reality, you can even connect AirPods to Android. Any device that supports Bluetooth could connect an AirPod. This article will guide you step by step on how to connect AirPods to Chromebooks.
Since AirPods supports Bluetooth and Chromebook natively supports Bluetooth, so you don't need any third-party application in this case to do the bit. However, if your needs are different than the Chromebook Bluetooth utility doesn't provide, then you should consider using a third-party application. However, that application will too use Bluetooth to connect your AirPods.
Overall, if you wanted to connect your AirPods to your Chromebook, activate your AirPods, head over to your Chrome Bluetooth utility, scan, and pair-connect with your AirPods.
