On Monday, Google announced that a new version of Google Glass is available. Current owners of Google Glass, known as “Glass Explorers,” can “swap” their devices for the new version. The new version of Google Glass supports future lines of shades and prescription frames. The second version of Google Glass also includes a mono earbud, which replaces the bone conduction speaker in the current version. The new version of Google Glass still has mono-only sound. Glass Explorers will receive three invites to the Glass program to give to their friends, but it will cost $1,500. The trade-in program will start in November.
