The iGe over its predecessor the iGi , has improved driver response, and with its proprietary wide bandwidth design, provides the listener with an unequalled performance at this price point. The iGe headphone is also the first of Grado’s headphones to include an Apple licensed controller which includes a microphone and offers the capability to control volume, music tracks, phone calls, and Siri. The addition of the controller makes this more than just a great sounding headphone, it now a communication tool to help you navigate the ever busy world we live in today.
