Riding my motorcycle for long periods of time without any sort or radio got dull quick. I started to wear my bluetooth earpiece inside my helmet, but it was anything but comfortable. So I decided to add bluetooth to my helmet, but helmet kits were expensive going over $100+. Looking around on amazon I found a cheap stereo bluetooth headset for just $25 which I integrated into my helmet. Here's how I did it.
Step 1: The Headset
The Bluetooth headset I used was the SoundBot SB2200. It cost me $25.
Step 2: Unscrew the Screws
After unpacking the headset, you're going to want to pull off the ear cushions. Then get your hands on a small flat screwdriver and work those screws off. They're non standard screws, but with a little maneuvering you can get them off no problem.
Step 3: Pull the Wire Out
Now with the earpieces apart, make note of where the wires go. You're going to unsolder them in order to remove the wire from the plastic neck strap.
Step 4: Make a Hole
Find a good spot to mount the controls on your helmet. Make a hole large enough to pass the wires through. I don't show it here, but I removed all the cushions from the inside of my helmet to make maneuvering of the wires easier.
Step 5: Mount It All
You're going to need some spare wire to extend the connection from the speaker to the main board. Also you're going to need to remove the microphone from the main board and mount it somewhere in your helmet. When you've done that, just run the wires to the hole in the side of the helmet and solder them back onto the main board. Use the previous picture for reference if you have to.
Step 6: Finished Product
Now for the finishing touches. I reattached the plastic pieces to the speakers and hot glued them in place inside my helmet. Then I removed the tape from the controls, placed them in an appropriate position and glued it down and made sure to glue all the way around rim so there were no gaps. Test it out. Mine worked great. It was loud, I sounded clear when i talked through the microphone. All for $25. Saved myself $100!
