Modern earbuds are throw-away products

I bought my Sony Linbuds S in May 2022. This is almost 3 years ago which seems to be the typical lifespan for earbuds like this. I don't know what I expected, but I am definetely disappointed that I need to buy new ones now.

At first, these buds where the perfect fit. Excellent sound quality, great battery life, really tiny and light and I also liked the skin-toned colour. But after two years, I noticed that the battery did not last as long as in the beginning and I was not the only one. Sony pushed a firmware update that drastically reduced the play time of these earphones. As more time passed and the battery got older, I got more and more annoyed by the voice "Low battery, please charge!". Recently, as I went for a run and started with full earbuds and came back home with completely empty buds after 45 minutes, Noice-cancelling was not even active. I decided that I needed to change something and ordered some spare batteries from Aliexpress.

The batteries came today and I was very excited to give my loved earbuds a second life. I was excited until I had my first issues with the glued casing. With a lot of patience, heat and some brutality, I finally managed to open up the case of the first earbud. But this was just the beginning. Sony used such strong adhesive that I ripped of a flexible pcb at the solder points to the speaker while opening the case.

Summary:
✅ New battery in right earbud
✅ New battery in case
❌ Broken left earbud ☹️

So what am I doing now? Unfortunately the new batteries will not help anyone here. I do not want to listen to music with only my right earbud.
Buying a product that is so difficult to repair was a mistake. But while there are great repairable options for smartphones already (I love my Fairphone 5), there are almost no repairable earbuds on the market. Almost? Yes there is one product which is 10/10 ifixit approved: https://shop.fairphone.com/de/fairbuds

However, I read some reviews online and some say that the sound can not compete with Sony earbuds at all. This was originally the reason why I decided to try to repair my old Sony earbuds before buying repairable and long-living earbuds as it might also mean a downgrade in sound quality. But now, as my repair failed miserably, I think there is not really another option than checking out the Fairbuds.

It is really sad that replacable batteries are not a thing in mainstream products.
