Audio specialist Sennheiser and sporting goods manufacturer adidas are extending their joint headphone line with the addition of the CX 680i Sports, MX 680i Sports, OMX 680i Sports and PMX 680i Sports models, designed for use with the iPhone.

“The remote and microphone unit integrated into the cable allow you to seamlessly switch between music and calls at the push of a button,” explains Eric Stubbert, channel manager for consumer electronics at Sennheiser Electronic Corporation. “If the phone rings, the music is automatically paused and restarts as soon as the phone call is finished. This ensures that you never miss an incoming call or your favorite song.”

The line is currently available now through Sennheiser”s distribution network and at Apple Online and in Apple Stores.
