Another thing we noticed is that the temples are a little thicker than your regular glasses. This is as all the electricals are placed inside them. This includes the speakers, battery, Bluetooth module, etc.
Also, the temples act as the power On and Off switch for Noise i1, thanks to the Hyper Sync technology that is claimed to connect with any device automatically on opening the temples. This means that when users open the glasses to wear, it automatically turns On and when closed it turns Off. This not only adds to the convenience of not needing to switch On or Off, but also helps save battery.
