Introducing the Bose SoundSport Free Wireless Earbuds. These audio innovations are truly wireless meaning there is no cable between them. With one in each ear, you get the full Bose surround sound experience throughout your workout. Despite packing in all that audio technology, they weigh just 0.35 ounces and remain in place however you move. The SoundSport Free Earbuds also have an impressive connection. They stay synced with your device even up to 30 feet away. But, the SoundSport Free Earbuds get their name from yet another great quality. The pair is not only sweat resistant but also water resistant. You can take your workouts to all new levels both physically and geographically. With five hours of battery life, they easily recharge in the included magnetic charging case.
