French consumer electronics and communication systems company, Sagem, has just released, what they are saying—could be the world's tiniest Bluetooth enabled headset, the H4. Its dimensions are 35 x18x12.5mm. The H4 weighs only 8 grams.

A store function (FPN—Favorite Phone Number), with the ability to save 2 most frequently used numbers into the device, is also available. This function allows the user to dial these 2 numbers without having to touch the phone itself. The H4 has a dedicated button for the FPN function and volume keys located on the other side of the device.

There is also an LED to indicate if the device is on or off and also when the battery is low on charge. The H4 has 5 hours of talk time and 100 hours of standby time. Sagem maintains that the headsets will take just 1.5 hours to charge completely.

The cost of this tiny headset is set at approximately $103 or £53 (Rs 4,500).
