Does it work? So far yes. The kit supplied offers more than the required tools to get the job done. Even some small elastic bands to hold the buds together for gluing if you don't have clamps are provided.Youtube gives you an idea of what you're going to face, so not spending a few minutes observing one or two tutorials is of course folly. With that in mind, it's best to acknowledge that sometimes the things you want to fix haven't seen these videos and even if they have, may have a rebellious streak in them.I didn't need to disconnect everything as shown in these videos, but there is a very narrow connector cable that if you decide to leave in place, caution would suggest levering its release catch up, thereby giving it enough room to slide itself out if it feels strained. Your journey to the land of music may well end up cut short in disappointment otherwise.Not all manufactured items are equal I experienced, as nudges with a tool on the sides and the battery floats into your arms like a long lost lover was the view depicted on these video streams. Well the magnet that held the battery down in one of mine didn't agree. Trying to keep a lid on frustration, I encountered a battery declaring squatters rights, seemingly stuck down with glue that decided doing its job is all that matters in this world. "No", the magnet uttered. "It's just me". Not disconnecting everything can make a situation like that a bit more challenging.With the potential for a nudge or pull too far whilst attempting to release a stubborn battery, hoisting it at a greater height than expected may result in the narrow cable deciding that you should have paid it more attention, likely meaning the end of your rescue efforts. Skip steps, but be wary, balancing speed with smarter execution is the way to go.I assumed only the battery in the right ear bud needed remedying, as this one died extremely quickly. However after replacing, it highlighted the fact the left bud, while not as bad, was also in need of attention.So far I'm quite pleased, but only time will reveal the quality of the battery replacements.

It works, good as new.

My 2yr old £150 Sony earbuds stopped fully charging and were losing charge in just 30mins so were next to useless (watch the Documentary Re: companies deliberately making things last a couple of years, I swear it is true!!) so I decided to replace batteries myself instead and it was a great decision! This comes with OEM replacement batteries and everything you'll need to change the batteries (bar the hairdryer and a rubber clamp). Lots of YouTube videos to guide you through the fix. It took me literally 30mins for both earbuds. These are original branded batteries which is what I specifically wanted.

Great kit - batteries are great! Its a fiddly job but my ear buds are like new!

Great kit with everything you need. Earpods now as good as new 😁
