XREAL, Viture, RayNeo and Rokid. No pairing, no account, no network.
These glasses are not a separate app or an integration. Each one is a screen that plugs into your iPad or iPhone with a single USB-C lead, so QMe simply draws to it the way it would draw to a monitor. That has one big consequence on stage: nothing travels over wifi, bluetooth or the internet, so there is nothing to drop out. The G2 is wireless and hands-free, which a cable can't match; a cable can't lose signal, which wireless can't match. They suit different gigs.
A USB-C port that carries video, which Apple calls DisplayPort Alt Mode. The USB-C iPad Pro has it, as do several iPad Air and mini models, and iPhone 15 onward. Older Lightning devices cannot drive these glasses at all, whatever adapter you use.
Plug them in. That is genuinely the whole thing. QMe notices the screen and starts sending it a lyric view: large text with the chords above the words, the line you're on in the middle, and what's coming next below. Your iPad keeps the full interface, so scrolling, pedals, MIDI, the metronome and recording all carry on exactly as before. The glasses are a second screen, not a separate mode.
Any screen QMe sends to can show the words for an audience rather than your own view. See Audience View.
Opens the real glasses view full screen on your own device, so you can judge the size and layout without owning a pair. Open a song first and it shows your own lyrics, following along as you scroll.
