Panasonic EB-M70083 the lightest Bluetooth earphones
Bluetooth headphones are cool but the only disadvantage the Bluetooth connectivity and seperate batteries make them heavy. This is not the case with the Panasonic EB-M70083 which are one of the smallest we have seen, it supports Bluetooth ver 1.2 along with A2DP/AVRCP/HFP/SPP profiles. You can use it with a compatible cell phone as they can also be used for making / receiving phone calls. The built in battery is good enough for 4.5 hours of wirefree music and 6 hours of telephone conversations.
The Panasonic EB-M70083 just weigh 25 grams and will be available in Japan from December 11 for 6,825 Yen ($ 60)
