Bose will soon release new in-ear headphones made specifically to work with multimedia-capable smartphones. The three will include the IE2 headphones and MIE2 and MIE2i mobile headsets. The last two have built-in microphones and call control buttons, with the MIE2i made to work with the iPhone, iPad, iPods and recent Macs, granting access to some of the devices' voice-capable apps and navigate music. Each will include proprietary Bose technology to boost sound quality and three sizes of StayHear tips more comfortable than with previous Bose in-ears.
