Everything you need to replace the batteries is included
Thanks go to the Amazon Vine Project for sending me the Z55H Battery, [2PCS] High Capacity Li-ion Replacement Battery for Sony WF-1000XM4. The batteries in my Sony WF-1000XM4 died months ago and they have been sitting on the shelf all this time. I went on YouTube and watched some videos where they explained very clearly the procedure for replacing the batteries. This kit included everything they mention that is needed to repair the earbuds so I figured I would give it a shot. The most difficult part of the procedure was using a heat gun to melt the glue and not burn my hand. After getting the earbuds apart, the rest of the procedure was very easy. If you have the Sony WF-1000XM4 do yourself a favor and buy this kit, it's way cheaper than buying a new set of wireless earbuds.

No how-to
I almost channel my frustration from my XM4 to this product by leaving a 2 star for the price, yet no instructions on how to use. Yeah, 'nother Sony victim of firmware bricking. Long story short, I cool down, and become a happier man. No longer I got cut short to 45Min of use from my right bud. The battery is the same brand with the one installed on the bud. The kit alone will not help you, because you need a heat gun. Thankfully, there are plenty of repair instructions online.
