A firmware update for Apple's AirPods is being distributed now, which brings undisclosed bug fixes to Apple's sought-after wireless earbuds.

Apple AirPods firmware 3.5.1 is available for users now, and in all likelihood, has already been downloaded to a synchronized device. Installation is automatic when the AirPods are in their charging case, the case is plugged into a charger, and the linked iPhone is in close proximity and connected to Wi-Fi.

Users can check the installed firmware revision in the "General" settings menu, by selecting "About," then "AirPods."

AppleInsider was told by a contact within Apple that the update contains "miscellaneous minor bug fixes." It is not clear at this time if the update does anything to reduce or eliminate the claims by a number of owners that the devices have connectivity issues.

AppleInsider went hands-on with the $159 wireless headphones and came away impressed with their advanced technology and ease of use. The earbuds include an Apple-designed W1 chip for easy pairing and Bluetooth connectivity, as well as beam-forming microphones, accelerometers, and a small charging and carrying case.
