Google glass failed because it was not a very good product - it was very slow to refresh, the screen was hard to see without rolling your eye up into your head, it cost $1500, and it didn't have any kind of killer app. These are a fifth of the price and are decent at doing the 2 things they set out to do. They have improved on everything I hated about spectacles and added budget airpods to the feature list.
