- Brand: Jabra - Model: Elite 4 Active - Usage Period: Approximately 1 year - Condition: Battery slightly degraded - Contents: Charging case, left and right earbuds Operation has been confirmed. There are no problems with operation, playback, or app connection. However, the battery does not charge to 100%. It seems the battery has degraded somewhat. I used them continuously for an hour for the first time in a while, and the battery only went from 90% to 80%, so it seems usable without significant degradation for now. 《Notes》 This is a used item stored by a private individual.
