The Bose AE2i is the iPhone-optimized headset version of the Bose AE2 headphones. The AE2i is identical to AE2 except for the inclusion of an inline remote and microphone. In addition to a microphone for phone calls, the inline remote offers controls for volume and answer/end call.
The AE2i is designed to work with iPhones, iPods, and iPads. Beyond the headphone function, the microphone and remote is not designed nor intended to work with other phones.
The Bose AE2i should deliver identical sound to that of the Bose AE2 headphones.
