Google Glass has released its second generation eyewear collection with a new range of titanium headsets. The “Titanium Collection” features the latest hardware update and a range of new styles including the “Edge” and “Classic” twist-on sunglasses, and the “Split” and “Curve” feather-light titanium prescription frames. The new range is available in five new colorways and includes an external mono earbud instead of the bone-conduction speaker from the first version. For those who are part of the Google Explorer program, you can update to the new Glass starting this week. For more information head over here.
