Lucky Google Glass Explorer owners will be able to swap their pair for a new updated pair later this year. As well swap their pair of Google Glass, they can invite up to three of their friends into the program, where they can buy their own pair - providing they have the cash for one.
Google has yet to give any solid information on what expect in the new updated models, but has teased everyone with some images posted on the official Google Glass Google+ page. The new pair now has a mono earbud however according to the comments placed by the official Google+ page the earbud is optional, so the bone conducting speaker will still be there.
The new pair have also now been designed to work with prescription frames so users who need glasses to see can now use their glasses as well as Google Glass.
