Could you please explain all the details of the indicator lights on the Monster Open Ear AC210 earbuds and the charging case, including what the various colors and flashing patterns mean?

Based on the manual for the Monster Open Ear AC210, here is the breakdown of the light indicators and their meanings:Charging Case Indicator: When you connect the USB-C cable, the indicator light on the case will illuminate to show the charging status. Typically, a solid or pulsing light indicates active charging, while it may change color or turn off once the 30-hour capacity is fully reached.Pairing Mode: When you open the charging case, the earbuds automatically enter pairing mode. During this time, the lights on the earbuds will flash to indicate they are searching for a Bluetooth connection. Once successfully connected to your device, you will hear an audio confirmation and the flashing will stop.Earbud Charging: When the earbuds are placed back into the case, the lights on the earbuds (or the case indicator) will signal that the contacts have met and charging is in progress.Troubleshooting Tips:One earbud not working: Since you mentioned cleaning the contacts, ensure that when you place the earbud in the case, the light for that specific earbud reacts. If one side does not light up, it may not be seated correctly or the battery may be too low to trigger the LED immediately.Resetting: If the lights continue to flash in an unusual pattern or the earbuds won't sync, try restarting your Bluetooth on your phone and placing both earbuds back in the case to reset the connection.Note: The provided documentation does not specify exact color codes (e.g., red vs. blue), but generally, flashing indicates a state of transition (pairing/charging) while solid or off indicates a completed state (connected/fully charged).
