World's most elite headphones for sports. For the last few years, we have been selling exclusively to government security agencies. We are now offering this unique earphone technology to the general public, because of demands from runners, cyclists, skiers, and office workers. The ability to comfortably listen to music or a cell phone and maintain constant sound awareness of your environment is what makes the earHero product a new paradigm shift in the earphone industry. We have used our audiology background to create a product that is safe, comfortable, and clear. We want you to enjoy a safer way to stay connected!
