The Gear Circle by Samsung is coming to the U.S. It has a lightweight and sweat-resistant design and serves as a wireless stereo headphone. The device vibrates when you receive a new call. The battery life is good for up to 9 hours of play time and 11 hours of talk time. Gear Circle also supports voice notifications using Text-to-Speech. It will be available at AT&T, Samsung.com, and Amazon.com later this month.
