How to keep active users supplied with music yet connected with their surroundings is an ongoing challenge. Some use microphones and software to blend outside noise with personal audio. Bose's Sport Open Earbuds take a different approach. Using the company's OpenAudio technology and a contoured ear hook, they sit above — not over, in, or on — the ear canal, providing audio while keeping the wearer attuned to the outside world. They carry an IPX4 rating for protection against sweat, heat, rain, and snow, and offer 8 hours of battery life.
