The screwdriver is too soft and just crumbles
Cannot attest to the quality of the batteries, but the screwdriver that came in the set is made of the worst quality metal out there. It just crumbles without unscrewing the screws in the earbuds

Awesome!
Very nice packaging with all necessary tools and even more than necessary tools lol. Will update this review after a year using these batteries

Overpriced.
Two useful batteries with a bag full of useless cheap "tools" just to make the price up.

Great battery replacement kit!
The process to replace the batteries is not simple, you do need care and a bit of experience will help you along the way to not mess things up. If this is not your first rodeo, then this kit has everything needed in order to replace the batteries. As for the battery quality, it's been almost 18 months since I did the replacement and they are strong, no sign of issues or low battery errors like the original ones.

Good batteries and just enough glue
These batteries are labeled ZeniPower Z55H and they work well with my sets of WF-1000XM4 earbuds. Besides the heat gun, this package included everything needed to swap out the batteries. These new batteries with a full charge lasted 5 hours 10 minutes with noise-cancelling, much improved.For such a premium set of earbuds WF-1000XM4 from Sony, I expected the battery to last more than two years. But it has only been 1 year and 3 months, and one of the earbud became useless because of only 10 minutes of play time. Then 4 months later, the other could last only 20 minutes. I was going to throws my earbuds away, but hanks to those tutorial videos online, I can give this set of premium earbuds a second life. It turns out that this battery problem was not an isolated incident. Shame on Sony.

1 batterie sur 2 fonctionne.....
Lors de mon remplacement de batterie, y'a juste une batterie qui fonctionne. Pour être sur j'ai mis l'ancienne batterie dans l'écouteur et c'est fonctionnel. Avec un multimètre, le niveau de batterie est dans la zone de sa mort. Donc j'ai juste une batterie de vivante....
