Google demoed the first pair of Android XR glasses, and a new type of live demo slip-up resulted in some private conversations echoing across Mountain View. That, right there, is why the speakers on Google’s Android XR glasses won’t be audible to anyone but you.

The first pairs of Android XR glasses will come from two brands in collaboration with Google: Warby Parker and Gentle Monster. The spec sheets between the two are essentially identical, barring any design differences – of which there are several.

Android XR glasses, in their current form, will carry cameras, mics, and speakers. It echoes what Ray-Ban and Meta have done for the first few generational releases. It’s simple, yet effective for a Gemini-founded experience. The user experience goes like this: summon Gemini via voice or touch, interact and/or look at the thing you want to ask questions about.

When Gemini answers, it won’t display on any in-lens display, because Google isn’t there quite yet. That’s coming later.

Any response from Gemini will be heard only through the built-in speakers on the Android XR glasses, and Google assured users that “under normal use… Gemini is going to privately be talking to us.” Meta has done this with wearables since releasing its VR headsets and the Ray-Ban Meta glasses, as long as volumes are kept at certain levels. At those clear-to-you volumes, the audio is imperceptible to those around you.

You can imagine why, but during a heartwarming, genuine interaction with Gemini during the live demo, the digital assistant blurted out a personal reminder for Google product manager, Nishtha Bhatia, to complete her daily affirmations.

The audio had been exported to the event speakers during the demo, but any other time that response would be quietly played for no one to hear.

As live demo slip-ups go, this one was as innocent as they come. Whether or not it was a planned part of the show, it’s a good reminder why Android XR glasses will play audible responses at a low level.

The first couple of pairs Google intends to release will hinge entirely on audio for Gemini. If you’d rather wait for a pair of Android XR glasses with a display, Google seemingly plans to announce a pair later down the road.
