The Explorer 370 Bluetooth headset of the Plantronics is very special, but not just because of the water- dust- and dropproof case. It prevents the ear of the called person by it's digital sound processor. It succesfully fights down the power of the wind and eliminates the sound of it nearly at all. The Explorer 370 headset meets the MIL-STD 810 patent of the American Army so it surely survives the hardships. The battery of the surviver headset is promising 7 hours talk time or 8 days stand-by time. The device is going to be available in March for at about 80 dollars.
