Responding to a “stability issue” with its TriPort in-ear headphones, Bose has announced that it will release an updated version starting next week. The “new” headphones, which are identical to the existing models, will include improved interchangeable ear tips in three sizes, which Bose says offer a better, more-snug fit. Later this year, Bose will offer a wire clip and a neck lanyard for the TriPort in-ear headphones. Those who’ve already purchased the $100 in-ear headphones can get all three upgrades at no charge. Starting March 16, owners can order the new accessories on the company’s website at bose.com/enhance.
