## Description

Replace Part Numbers: Z55H Fit Models: WF1000XM4 WF-SP900

Review: Work as Intended - Needed new batteries after my earbuds started dying after about 10-15 minutes of use. After replacing I used them for about 2 hours and still had 88% battery life yet, so all good thus far. At the time of purchasing, these were about $7 - $10 dollars cheaper than other sellers who included all of the tools and glue needed for the replacement. Well worth the savings if you don't need the extra tools.

*by A***R on May 9, 2024*

I am a victim of the Sony WF-10004 ear bud bad battery debacle. I found a video on how to replace the batteries. So far these are working fine and last longer than the 15 minutes the original batteries did.
