Make a DIY Bluetooth Adapter!

In this post I show you how I made my own Bluetooth adapter to connect my corded headphones.

I avoid wireless devices and only use devices with wire, although I had bluetooth devices, such as headphones.

However, because I have watched a few videos where they test bluetooth devices their frequencies, and because there is a suspicion that they might cause problems, I decided to convert the only bluetooth device I still used, my headphones. Sure, you can buy a Bluetooth adapter but where's the fun in that?

So, I thought that this particular box would be the best solution, that is, to use my good quality wired headphones, but without connecting them with cable.

My bluetooth adapter.

So in the box I "squeezed" a bluetooth receiver, a on-off switch and an 3.5mm audio jack (female connector). It is powered by a mobile charger (5VDC), since I have attached a USB cable to the power input, so that it can be powered by almost all devices.

As you can see in the image above, the device has a switch to turn it on and off and a headphone output. Headphones can be connected with a 3.5mm audio jack and as I previously said, it is connected directly to a mobile charger, so that there is no need for charging, since I am tired of this constant charging of my devices (smartphone, headphones, hands-free, smart watche, videogame controllers etc.).

I've been using the device for over a month now and I'm happy. The sound is very lound ans clear due to the fact that my headphones have a high sensitivity in dB, so I didn't need to put an additional amplifier in the box, the one the receiver has built-in is enough for me.
