So far so good
Spent ~10mins to replace the battery of my WF1000XM3. They work perfectly so far! I will update here is I see any drop in capacity sooner than expected (at least 1 year from now). Hope I won't have to update my comment~. fingers crossed.

Revived My WF-1000XM4 Earbuds
After two years of daily use, my Sony WF-1000XM4 earbuds started to show signs of battery degradation. The left earbud wouldn't hold a charge for more than 30 minutes, which was frustrating. I was hesitant about replacing the batteries myself, but this Z55H 75mAh Battery Replacement Kit made the process manageable. The kit came with all the necessary tools, including a spudger, tweezers, and adhesive. The installation was a bit intricate, especially when detaching the old battery, but following an online tutorial helped immensely. Once installed, the new batteries brought my earbuds back to life. They now hold a charge close to their original capacity, and I can enjoy my music without interruptions. Overall, this replacement kit was a lifesaver. It saved me from purchasing a new pair of earbuds and extended the life of my current ones. If you're comfortable with small electronics and have steady hands, I highly recommend this kit.

Work fine
They work well. The only thing missing is the adhesive to close the ear buds once you finish the replacement.

Nueva vida para mis audifonos
Funcionan perfectamente para unos audifonos Sony WF-1000XM4, a los que solo les duraba la batería aproximadamente 15 minutos durante llamadas telefónicas. Son fáciles de reemplazar siguiendo cualquiera de los muchos tutoriales que hay en YouTube, sería un producto redondo si le incluyeran el pegamento para volver a sellar los audífonos. Aun así sigue siendo un excelente producto, ahora vuelven a su autonomía de 8 horas.

Look somewhere else
This is not the 1st time I replaced batteries on my 1000XM4 ear buds, but after I swapped with these ones they completely died. Pure frustration
