How To Make Wired Headphones Wireless

Tired of tangled wires? Upgrade any of your headphones to wireless. This requires only a few parts.

📋 Materials I Used:

* VHM - 314 Bluetooth Audio Receiver
* TP4056 5V 1A Type C 18650 Lithium Battery Charging Module (with battery protection)
* 2 Position DIP Switch
* I used 2 old mobile phone batteries as the power source and an 18650 Lipo battery

Battery one - 1800 mAh
Battery two - 1020 mAh
18650 Lipo - 2000 mAh (You can use any suitable 3.7v battery like this)

''important'' - Make sure all your batteries are charged separately before use. Because all the batteries are at different charge levels. For this project, the batteries have to be connected in parallel. Then, when one of the three batteries is fully charged, the module stops charging. But here, only one battery is fully charged, the other two batteries are in different states. That's why I charge them separately first.
if you don't have high-capacity batteries, this project's 500mAh battery is enough for minimum 2-hour playtime. You can also use it while charging if the battery is low.

* If you want to improve this more, you can use these two modules.

- VHM-314 Version 2.0 | Bluetooth Receiver board 5.0
- IP2312-18650 3A Fast charging module

this can improve your sound quality and fast charge your headphone

If someone asks, why we use the VHM 314 module we can use some Bluetooth adapters from Earphones.
yes, you can. this can get more benefits like using the mic, and seeing the charging level in your phone.
The VHM-314 Module design for DIY works. You know some people don't know anything about electronics. this module is made for these guys. all the instructions are printed on the board and its simple design. actually, this also can be used without soldering (using USB and AUX cable). So it's better if you can make do with another Bluetooth adapter.
