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.
