Does some one have idea to make a simple wirless mic with bluetooth cellphone's ear mouth piece or modify the walky talky.

Well... simplest is to use two walkie talkies and just plug the earphone socket of one walkie talkie to the mic of your camera.... but it will be poor quality. I think You can buy some cheap and cheerful radio mics that will probably give better quality than you could ever hope to bodge.

Go on ebay and pick up a cheap radio mic... far better and cheaper than trying to make something yourself. You can pick up Chinese crap for less than a tenner. Just remember that with microphones you get what you pay for, the chinese cheapo will sound better than your bluetooth idea but nowhere near as good as an AKG or Sennheiser set.

yeah there are plenty of cheep radio mics about.. they may not have the best sound but they will be a damn sight better that walkie talkies!

I was talkign to my dad (whos in the audio industry) and he was telling me that the company he works for was going to create a bluetooth wireless microphone. Unfortunatly Sony got in first and came up with this-
