Wireless headphone with Microphone
Can anybody tell me how to make a wireless headphone and microphone. Both microphone and headphones should be wireless. I found that one can buy a wireless headphone or a wireless microphone, but not a combination of both.
Why I need it. I make long phone calls, during which I need to walk around. If I use a cordless phone, I have to keep holding the receiver with one hand all the time. If I use a speakerphone, everybody around listens to the conversation. Therefore I need one wireless headphone with mic.
