Wondering if smart glasses with speakers can replace your earbuds? For calls, podcasts and casual music, often yes. They use open-ear speakers that leave your ears uncovered, so they trade isolation for awareness.
They sit in the wider world of wearable audio, and this page covers how the speakers work and what to check before buying.
| Item | Value |

| Battery per charge, typical use (Gen 2) | Up to eight hours |
| Extra charge from the case | An additional 48 hours |
| Fast charging | Up to 50% in 20 minutes |

Figures come from Meta’s 2025 announcement of its Ray-Ban Meta (Gen 2) glasses. They are the maker’s claims and can change, so check the source before you rely on them.
How do smart glasses with speakers work?
The speakers are built into the temples, the arms that run along the side of your head. They point sound toward your ear canal without sealing it, which is why the design is called open-ear.
Because nothing blocks the ear, you keep hearing traffic, colleagues and announcements. Meta even uses this design for a feature called conversation focus, which, in its words, “uses the glasses’ open-ear speakers to amplify the voice of the person you’re talking to.”
The glasses also carry microphones, a battery and a Bluetooth radio, all packed into the frame. That is a lot of hardware in a small space, and it shapes both comfort and sound quality.
What you gain and what you give up
Open-ear audio suits some routines much better than others. Think about where you will wear them most.
- Situational awareness: walking, cycling in quiet areas and commuting feel safer when you can still hear your surroundings.
- Comfort: nothing sits in your ear, though frame pressure and listening fatigue can still affect comfort.
- One device: a single pair handles lenses, calls and audio, so there is less to carry.
- Weaker bass: without a seal, low frequencies are thinner than in good earbuds.
- No real noise blocking: loud streets and planes will drown out quiet passages.
If you mostly listen on noisy trains, a sealed earbud still does the job better. If you spend your day among people and want to dip in and out of audio, open-ear glasses fit well.
Sound leakage and privacy
An open design means some sound escapes. Leakage can become more noticeable at higher volumes in quiet rooms.
In practice, you can hear a faint version of the sound from a neighbour on a silent train, but not much in a busy office. Lowering the volume can reduce leakage; check whether someone nearby can still hear it.
Fit matters too. Check the manufacturer’s fitting guidance for the intended speaker position.
If you often listen in libraries, meetings or on night buses, test the glasses in a quiet room before you commit. Ask a friend to stand an arm’s length away and tell you when they can hear it.
Is it safe for your hearing?
Open-ear does not mean risk-free. Volume and listening time decide the risk, whatever the speaker design.
The World Health Organization and the International Telecommunication Union published a WHO-ITU safe listening standard. Its stated purpose: “The aim of the standard is to reduce the risk of hearing loss among users of such products.”
One trap is that uncovered ears can make you feel the sound is quieter than it is, so people nudge the volume up in noisy places. Treat these habits as a baseline:
- Do not use your ability to hear conversation as proof that the listening level is safe.
- Take breaks from long sessions.
- Do not raise the volume to beat street noise; move to sealed earbuds in loud places instead.
- Use any listening-time or volume-limit features your phone offers.
What to check before you buy
Specifications look similar on paper, so focus on the things you will notice every day.
- Battery and case: Meta’s Gen 2 claims up to eight hours with typical use, plus a case that adds 48 hours. Real-world results shift with music, calls and camera use.
- Prescription support: check whether your lens prescription and frame shape are covered, and the price of lens options.
- Weight and fit: glasses with more hardware can feel heavier on the nose bridge. Try them on if you can.
- Controls: touch panels on the temple, voice commands and phone apps vary between brands.
- Camera or no camera: audio-only models skip the camera, which may suit places where recording is sensitive.
- Return policy: comfort and leakage are personal, so a trial period helps.
Alternatives worth comparing
Glasses are one open-ear route among several. If you mainly want sunglasses with speakers and fewer smart features, look at audio sunglasses, which often cost less and focus on sound.
If you want a sealed or semi-open fit with long battery life and no frame to wear, a collar-style option is another route. Our page on neckband bluetooth headphones explains how those compare.
Many people end up owning two: glasses for walking around and sealed earbuds for flights and gyms.
Price is the other deciding factor. Meta’s announcement lists its Gen 2 glasses as “starting at $379 USD”; check the price for your chosen frame and lens options.
Everyday uses that suit open-ear glasses
The best way to judge a pair is to match it to what you do in a normal week. Here are the situations where the speakers tend to earn their place.
- Walking and errands: you can follow directions or a podcast and still hear crossings, bikes and people speaking to you.
- Working from a café or shared office: low-volume background music or a call works without cutting you off from colleagues.
- Short calls: the microphones in the frame let you take a call hands-free while carrying bags or pushing a pram.
- Cooking and chores at home: you hear the kettle, the door and the family while a playlist runs.
They are a weaker choice for gym sessions where sweat and movement matter, for flights, and for any place where you need silence to concentrate. In those cases the lack of a seal works against you.
Think of open-ear glasses as an awareness tool first and a high-fidelity music tool second. If you accept that trade, the sound is usually good enough for speech and everyday listening.
Setting up and getting the best sound
A few small steps make a clear difference to how the speakers perform. None of them need extra gear.
- Pair the glasses with your phone and keep the companion app updated, since software changes can improve controls and sound.
- Follow the manufacturer’s fitting instructions and check that the frames sit comfortably.
- Start with the volume low and raise it only as far as you need.
- Try a few audio types, such as speech, music and calls, because open-ear designs suit voices best.
- Clean the speaker grilles gently with a dry soft cloth, as dust and skin oil can build up there.
If sound feels thin, check the fit before blaming the glasses. A small shift of the temples often improves both volume and clarity.
Frequently asked questions
Can other people hear my music through smart glasses?
Show answer
At low or moderate volume, mostly no. At high volume in a quiet room, people nearby may hear a faint version, because the speakers do not seal your ear.
Do smart glasses with speakers block outside noise?
Show answer
No. Open-ear speakers leave your ears uncovered, so you hear your surroundings along with the audio.
How long does the battery last?
Show answer
For Meta’s Ray-Ban Meta (Gen 2), the company says up to eight hours with typical use, per its 2025 announcement. Other brands differ, and heavy use shortens it.
Are open-ear speakers safer for hearing than earbuds?
Show answer
Not automatically. Loudness and listening time drive hearing risk, so keep the volume moderate and take breaks.
