Help someone hear by buying a set of headphones for yourself. Los Angeles-based LSTN draws upon the buy-one, give-one model popularized by companies such as TOMS Shoes and eyewear purveyor Warby Parker. Inspired by a YouTube video documenting a deaf person hearing for the first time, Bridget Hilton and Joe Huff, who make strikingly chic, design-quality headphones out of reclaimed cherry, ebony, zebra and beech wood, founded LSTN in order to donate a portion of the company’s proceeds to the Starkey Hearing Foundation, which travels the world to fit people in need with hearing aids. Their trifecta of products — the oversize Troubadour ­headphones ($150), the compact Fillmore travel headphones ($100) and the sleek ear buds ($50) — draws upon the natural acoustic properties of wood, often sourced from the global communities they assist. Since launching LSTN in April 2013, Hilton and Huff have traveled to Peru, Uganda, Kenya and various cities across the United States to fit 15,000 people with hearing aids. Next up are India, Mexico and China. It’s truly a global mission focused on looking good, sounding good and doing good. “We didn’t want to start another headphone company,” Huff explains. “We wanted to start a company that could change the world through the power of music.”
