Plantronics has always been a traditionally strong brand name in the Bluetooth headset market, with popular products such as the Plantronics Voyager 855 and the Voyager 520 that emphasize style and performance. This year, Plantronics has decided to take a tiny detour from the style department into the great outdoors with the Explorer 370. Yes, the Explorer 370 is probably one of the world's first rugged Bluetooth headsets, military-certified to withstand the elements. It is a bit on the bulky side, but sound quality is good and it's not too pricey at $79.95.
The Explorer 370 is one tough Bluetooth headset. Measuring 2.25 inch long by 0.9 inch wide by 0.5 inch deep, the Explorer 370 is slightly bulky, with a thick rubberized outer shell to help it withstand shock and drops in temperature. The whole headset is military-certified under code MIL Spec 810, meaning it has been subjected to a battery of military testing, including water immersion, impact shock, solar radiation, sand and dust, and extreme temperatures. Indeed, you can tell the Explorer 370 is solidly built. We tossed it around the office, throwing it from one end to the other. We even dunked it in some water, with no ill effect. The ear loop is securely fastened on to the headset as well. Even though the Explorer 370 is big and bulky, it's definitely well-suited for outdoor activities.
