It's been in service for about a month and the headphones have been holding a charge like new. It is great to be able to extend the life of electronics. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Ausdom ANC8 headphone repair *by T***M on Reviewed in the United States on March 2, 2023* Used this battery to repair my favorite headphones that would only last an hour, they now last around 8 hours like when they were new.
