Ant-Man's Helmet: Ant-Man also wore a cybernetic helmet designed by Henry Pym permitting him rudimentary communication and control of insects. He could broadcast to a range of about one mile (1.6 km), depending on the materials surrounding him. His helmet also contained sound amplification equipment which also shifted the frequency of his voice so that he could be heard by normal-sized humans despite his diminutive size, as well as providing its own oxygen supply.
Ant-Man's Wrist Gauntlets
Ant-Man's wrist gauntlets enabled him to fire bio-electric blasts of adjustable force. His original helmet was able to fire 'disruptor' blasts of concussive force that Lang said were less powerful than the stings of The Wasp.
