Starkey Hearing Technologies, Eden Prairie, said that Seattle Seahawk and Super Bowl XLVIII champion Derrick Coleman, the NFL's first deaf defensive player, has become an official ambassador for the company. Coleman, a wearer of Starkey products since he began his career in the NFL, was recently the first to be fitted with Halo, Starkey Hearing Technologies' new made-for-iPhone hearing aids. As part of the new partnership, Coleman will be an advocate of Starkey's power products, which are specifically designed for those with ­severe to profound hearing loss.
