Best Smart Glasses for the Hearing Impaired: Live Captions in the Lens

What captioning glasses actually do

A microphone — usually your phone's, sometimes the frame's — listens to the room. Speech recognition turns it into text. The text appears in a small display built into the lens, where only you can read it. You keep your head up and your eyes on the person talking instead of on a phone screen, which is the entire point: it is the difference between following a conversation and transcribing one.

What they do not do is change the sound. No pair on this page makes a voice louder, clearer or easier to pick out of a noisy restaurant. If that is the problem you are solving, skip to the amplification section below and read our audio glasses for hearing loss roundup, which ranks that shelf properly.

The captioning pairs, side by side

Why XRAI is first and AirCaps is second

XRAI AR2 wins on the thing you cannot buy back later: it captions with no internet. Unlimited offline captioning is built into the hardware, so the glasses still work in a basement meeting room, on a plane, or on any day the subscription lapses. Captions across a full display in both lenses read more naturally than a strip in one lens, it is 49 grams, and 8+ hours with up to 96 in the case covers a working week of intermittent use.

AirCaps wins on knowing who said it. In a meeting or round a dinner table, a wall of undifferentiated text is only half the information — HearingTracker singles out AirCaps' speaker identification, and the maker publishes 97% accuracy when cloud-connected across 60+ languages. It is second because that accuracy figure is the cloud figure and there is no full offline mode, which makes it the more conditional purchase.

The mainstream option, and what it is not

Meta Ray-Ban Display puts live captions in the right lens of a pair of Ray-Bans, along with a camera viewfinder, walking navigation and messages, for $799. HearingTracker's framing is the correct one: it is a mainstream AI device with a captioning feature, not an accessibility device. Meta advises facing the person speaking, the display is monocular, and captions are one item on a long feature list rather than the thing the product exists for. If you want captions and a camera, or you want glasses nobody reads as assistive technology, that trade may be worth it — the full write-up is Meta Ray-Ban Display explained.

The Even Realities G2 is the quiet alternative: 36 grams, no camera, no speakers, about two days of battery, the widest prescription range on this site at -12.00 to +12.00, and green text in both lenses that covers captions, notifications, navigation and a teleprompter. Tom's Guide called it “privacy for you and everyone else”. It is a general-purpose display pair that captions, rather than a captioning pair.

The other shelf: amplification, and why it is regulated

Nuance Audio Plus is a different kind of object. It is an FDA-cleared over-the-counter hearing aid for adults with perceived mild-to-moderate hearing loss, built into prescription eyeglasses, with a directional beamforming microphone array and about ten hours a charge, from $829. HearingTracker's lab testing of the original model gave it an “A” SoundGrade and 3.9/5 overall, with 3.8/5 for speech in quiet and a standout 4.7/5 for own-voice naturalness — and 2.3/5 for speech in noise, which is the honest weak point of any open fit.

Two consequences worth stating plainly. First, if your difficulty is hearing one voice in a loud room, captions may genuinely serve you better than amplification, because a captioning system only has to recognize the speech, not separate it acoustically. Second, if your loss is more than mild-to-moderate, neither shelf is the answer — that is a clinic and a fitted device. Our Nuance Audio vs hearing aids comparison goes through that decision with the lab numbers.

Five things to check before you order any of them

• Does it work without internet? Only XRAI bundles unlimited offline captioning. For everyone else, no signal means no captions.
• One lens or both? Meta's display is monocular and sits in the right lens. XRAI, AirCaps and the Even G2 put text in both.
• Can it take your prescription? XRAI sells an insert, AirCaps supports prescription lenses for about $150 more, Meta covers -4.00 to +4.00 for $200, and the Even G2 goes to ±12.00.
• Does it identify speakers? Standard on AirCaps, on XRAI's top tier, on neither Meta nor the Even G2. In groups this matters more than raw accuracy.
• What is the return window? AirCaps publishes 15 days risk-free. Buy where you can send them back, because whether captions work for you is something you can only find out in your own rooms.
