Personally, people with a bluetooth headset in my ear make me smile on the streets. Especially when they don't speak it. Apparently they were fascinated by childhood watching the movie Robocop and they think to surprise people with their gadget. Fortunately for more creative people, there is a good option on the market for bluetooth headsets. It is interesting to look at the reaction of people when the phone rings and you take out such a device from your bag and start talking. Charging lasts for 3 hours of conversation. Price: USD 29.95
