Panasonic Technics EAH-AZ80 Right ear only Color: Silver Eartips: All types, only one earbud sent Compared to the left ear, the sound feels slightly quieter. Battery life is not a particular issue. I was only using the L size eartips. I will ship after initializing, so please re-pair the left and right earbuds and configure settings in the app (Technics Audio Connect) yourself. The condition is based on my personal subjective assessment, so please refer to the photos. Please consider purchasing only if you understand that this is a used item and are willing to overlook minor imperfections.
