While we're guessing most of you likely won't be putting the military grade-ness of Plantronics' new Explorer 370 Bluetooth headset to the test, you'll likely still find it a little reassuring to know that it passes all the requisite specifications for water, dust and shock resistance, and boasts a new "windscreen technology" to ensure clear calls even in tough conditions. Apart from that, however, the headset appears to be a pretty standard deal, with it boasting seven hours of talk time and eight days standby on a charge, and the usual features like voice-activated dialing and last number redial. Look for this one to set you back $80 when it hits retailers in March, with the less rugged Explorer 360 also set to be available at the same time for $70.
