If you are interested in DIY wired earphones, you may want to take a look at this article.
If you happen to have a non-in-ear touch-control Bluetooth headset, you will find it very convenient to use. Its biggest advantage is that it hangs on your ear securely and is less likely to fall off. It does not go into your ear, so it feels more comfortable. However, it also has many drawbacks. First, the touch power-on is too sensitive, and it turns on with just a light touch. Second, when you try to turn it off by touching it, it does not respond. Third, it will automatically power off when there is no Bluetooth connection. As a result, every time you want to turn it off, you also have to turn off Bluetooth on your phone. This makes it very inconvenient to use.

At this point, you suddenly come up with the idea of combining it with wired earphones, so that it becomes more convenient to use. Coincidentally, you happen to have an LG earphone, so you can start making it.

First, you disassemble the Bluetooth earphone and remove the mainboard and battery, leaving only the speaker.

Finally, you re-solder the wires, and it is done.

Done. This modification is quite simple, but very practical!
