Y’know, when friends call and tell you “The Eagle has Landed, prepare for extraction,” it’s hard to mutter “whiskey, tango, foxtrot” into one of those standard mono Bluetooth headsets without feeling like a bit of a douche. This is exactly why military and security audio supplier Iasus has released their 500k earpeice, complete with transparent coil and push-to-talk button. The 500k is designed for specifically for prolonged use, because you never know when you’ll have to dive in front of the President to take a bullet. The rugged PTT button also allows music pause and play functions, for those long, lonely rooftop sniping stakeouts. Available for iPhone and BlackBerry for $99.99.
