Great replacement battery for Sony wf-1000xm4
After watching you tube videos replaced right ear bud battery after severe battery drain. (Previous battery lasted only 15 mins playtime compared to the left bud lasting hours. )While blog posts suggest is a Sony firmware issue, the new battery solved my problem.Fiddly to fit but within the skills of a hobby modeller.
