Smart glasses for lawyers— where they help, where they can’t go.

Where glasses earn their place in a practice

Most legal work is conversation followed by writing it down. A legal pad forces you to choose between listening and recording; a laptop on the table puts a screen between you and a client who is already nervous. Glasses that capture audio let you look at the person and still leave with notes. There are four places in a practice where that trade is worth making.

1. Client intake and meeting notes, with consent. The OXIVUE M08Ccaptures room audio through the microphones in the frame and produces a transcript in the free HeyCyan companion app. Say so at the start: “I’m capturing notes so I can listen properly — is that all right?” A client who says no has told you something useful, and the pad is still in your bag.
2. Site visits and evidence walk-throughs. An accident scene, a property in a boundary dispute, a construction defect, a workplace in an injury claim. Hands-free 8 MP photos and video let you document the layout while you walk it and talk to the person showing you round. On a wet or dusty site, the M02C carries an IP65 rating and weighs about 41 g. Your own footage is a working record for the file; whether it becomes evidence is a separate question of foundation and chain of custody that the glasses do not answer.
3. Calls between hearings. Open-ear speakers sit near the ear, not in it, so you can take a call in a corridor and still hear your name when the clerk calls the case. The M08C budgets 4 hours of calls on a single charge.
4. Conversations with clients who speak another language. Two-way translation across 40+ languages on the M08C gives you the gist of an initial conversation before an interpreter is arranged. The limits of that are real; they have their own section below.

What ties these together is that you are a participant in the conversation and the other people know the glasses are recording. Recording law turns on exactly those two facts. Federal law sets a one-party-consent floor, and a number of states require the consent of every party; our recording laws by state guide has the table. For a lawyer the practical rule is stricter than any statute: tell the room, every time.

The courtroom: assume no

Courts regulate cameras directly, and a camera in a frame is still a camera. In federal criminal cases the rule is explicit.

Federal Rule of Criminal Procedure 53: “Except as otherwise provided by a statute or these rules, the court must not permit the taking of photographs in the courtroom during judicial proceedings or the broadcasting of judicial proceedings from the courtroom.”

On the civil side, the Judicial Conference’s cameras-in-courtrooms policy lists the circumstances under which federal judges may authorize cameras, which means the default is that they have not. State courts write their own rules, and courthouse security policies often go further than the courtroom rules, restricting recording devices at the door. None of this is legal advice for your jurisdiction; you will know the local rules better than we do. The point is the direction of the default.

Two consequences follow. First, “I won’t press the button” is not an answer a bailiff or a judge is obliged to accept — the device, not your intention, is what the rule is written about. Second, if you need the audio and calls in court but not the camera, the frame has to have no camera. The OXIVUE M01 Prois that frame: its spec sheet reads “None · audio only”, with open-ear audio over Bluetooth 5.4, roughly 28 g, 8 hours of listening or 6 hours of calls. It has no AI, so it does not transcribe or translate. It is on reserve at $19.90, with no payment taken today. Our camera-free glasses for work guide covers it in full. Even an audio-only frame may be restricted in a particular courtroom, so the rule is still to check.

Privileged conversations and client data

The recording question is about consent. The privilege question is about where the words go afterwards, and it is the one lawyers are better placed to answer than we are.

What we can tell you plainly about the OXIVUE setup:

• The M08, M02C, M08C and M14 pair with the HeyCyan app, free on iOS and Android and published by Shenzhen Qingcheng Future Technology Co., Ltd. Translation, the voice assistant, firmware updates and moving photos and video off the frame go through it. More in our HeyCyan app guide.
• Translation is not fully on-device. It calls out to a service. We make no claim that transcription stays on your phone, and you should not assume it does.
• There is no subscription and no per-minute metering, which is a cost point, not a confidentiality one.

So the working rule for a practice is: use the glasses where a record would be made anyway and the client has agreed to it; do not use them for strategy discussions, settlement positions, or anything under privilege or a confidentiality agreement until you have satisfied yourself about the data path under the confidentiality rules that govern your practice. If your firm has a policy on third-party apps handling client information, the HeyCyan app falls under it like any other.

Translation with clients: the gist, not the record

Live translation is the feature most likely to be misused in legal work, because it works well enough to feel authoritative. On the M08C it runs two-way: you hear the client’s side through the open-ear speakers and they hear yours, one to three seconds behind natural speech. See the translation page for how coverage compares across the range.

What it is not:

• Not a certified interpreter. It carries no certification of any kind. Depositions, hearings, sworn statements, and advice a client will rely on need a qualified human interpreter.
• Not a documented language list.OXIVUE publishes “40+ languages” for the M08 family and 139 for the M14, and does not publish which pairs work or how accurately. Before relying on it with a client, test your specific pair with a fluent speaker.
• Not a transcript of what was said. A machine translation of a conversation is a summary of intent. Anything that matters goes back through an interpreter.

Where it genuinely helps: the first call from a potential client, directions and logistics, a site visit where the owner speaks another language, or confirming a meeting time. That is the gist, and the gist is often enough to know whether you need an interpreter at the next meeting.

Which frame for which part of the practice

On battery: the M08C’s ~300 mAh cell is budgeted for 7 hours of listening, 4 hours of calls or 2 hours of video. A morning of client meetings is comfortable; a full trial day of continuous capture is not, and should not be happening anyway. The meetings-first version of this guide is smart glasses for meetings, and every spec sits side by side on the comparison page.

Bottom line

For a lawyer, the M08C at $169 is the frame that fits the office and the client meeting: metal trim that reads as eyewear, transcription in the app, and translation for the gist. The M02C at $159 is the one for site visits, and the M08 at $149 is the lowest-cost way to find out whether the workflow suits you. None of them belongs in a courtroom during proceedings, and none of them should hear privileged strategy until you are satisfied about the data path. For camera-banned buildings, the M01 Pro is the audio-only answer.

In the US, the M08C and M08 in Sunglasses or Clear lenses and the M02C in Sunglasses ship from the Chicago, IL warehouse, typically arriving in 5–9 business days; Photochromic lenses, the M02C in Clear, and international orders run 9–14 business days. Shipping is free from $99. Every eyewear frame carries a 2-year warranty against defects, handled as repair or replacement. OXIVUE does not offer refunds except for transit damage — see the return policy — so decide whether recording from your glasses fits your practice before you order.
