iPhone Stereo Headset

歴史的背景

Introduced on June 29, 2007 with the original iPhone, it was Apple's first headset with a microphone. Based on the classic round earbuds, it added a control capsule with a microphone and a single squeeze-actuated button on the left earbud wire for calls and music control. Bundled with the original iPhone and iPhone 3G and sold separately for $29, it was replaced in 2009 by the Apple Earphones with Remote and Mic.
