Personal audio hardware maker Sennheiser on Monday introduced six new headphones made especially for Apple's mobile products, including the iPhone 4, iPhone 3GS, iPod touch and the iPad. All are designated by an 'i' badge and sport an in-line remote and microphone that lets users control playback as well as make phone calls or record audio. All are based on existing Sennheiser products, and include the IE 8i, MM 70i, PX 100-Iii, PX 200-Iii, HD 218i and HD 238i.
