Key points:

• Battery-drain issues: Many users have experienced rapid battery depletion in one earbud, leading to significantly reduced usage time. [1]
• Overheating during charging: Some users have reported that the affected earbud becomes unusually hot while charging, indicating potential battery damage. [2]
• Firmware-update concerns: The 1.4.2 firmware update is commonly associated with these battery issues. Users have noted that downgrading to earlier firmware versions may alleviate the problem, but this is not a guaranteed solution.
