Jawbone recently introduced the ERA, its smallest, lightest and most ergonomic Bluetooth headset yet. The product of three years of development and user testing, the ERA boasts a new shape that uses the natural contour of the ear, allowing it to be comfortably worn throughout the day as the user listens to music, makes calls and communicates with virtual assistant applications. It is 42% more compact than its predecessors and features a long-lasting battery that gives it almost 10 hours of talk time and comes with a sturdy aluminum charging case. Its behavior and functionality can be customized via the Jawbone app for smartphones. Priced at $130, the ERA is available for order through Jawbone’s website.
