This listing is for the main unit and charging case only. The charging case and left earbud function normally. The right earbud can connect, but the sound is very quiet. Therefore, it will be treated as a defective item. Other notes: Please consider this item with the understanding that it is a "defective item." We cannot provide support for any issues, including operational defects and problems during setup. Thank you for your understanding. #Anker #soundcore #WirelessEarphones #WirelessEarbuds #Bluetooth #DefectiveItem
