Triathlon sunglasses with audio and a camera: for training, not the swim
Most triathlon sunglasses are plain race eyewear, and for race day that is what you need. Smart sunglasses earn their place in training: open-ear audio on long rides and runs, a camera for the sessions you want to remember. This guide covers where they fit, what USA Triathlon's rules say about race day, and why they never go in the water.

1. Where smart sunglasses fit in triathlon
Search Google for triathlon sunglasses (checked October 9, 2026) and the results are race eyewear: retailer collections, triathlon magazine round-ups and forum threads where athletes compare frames for the bike and the run. Those pairs do one job, which is to sit still on your face for hours while you go hard. If that is what you are shopping for, a plain pair of sports sunglasses is the right buy.
Smart sunglasses solve a different problem. Triathlon training means a lot of solo hours: long rides on the weekend, easy runs, brick sessions where you go straight from the bike into a run. A pair with open-ear speakers lets you take a call, hear a podcast or follow navigation prompts without sealing your ears. A camera in the frame lets you capture a climb or a new route with a touch on the temple, without stopping to pull out a phone.
So the honest framing is this: smart sunglasses are for training. On race day, either wear them as ordinary sunglasses with everything switched off, or leave them in your bag and race in your usual pair.
2. Race day: what the rules say about audio and cameras
USA Triathlon publishes its rules on its multisport rules page. Under the heading “Headphones and Communication Devices” (checked October 9, 2026), it says participants may carry a phone but “may not use communication devices of any type” in a distractive manner during the competition. Its list of distractive uses includes making or receiving phone calls, playing music and taking photographs, and it states that using a device this way may result in disqualification.
Every feature that makes smart sunglasses useful in training (music, calls, photos) is on that list. In a sanctioned race, keep the audio silent and the camera untouched, or do not bring them at all. Races run by other organisers, and races outside the US, set their own rules, and they may restrict audio devices or cameras differently. Read your race’s athlete guide before you decide what to wear, and ask the race officials if you are unsure.
3. M14 vs M02C for triathlon training
We make two frames that suit triathlon training. The table shows how they differ on the points that matter for the bike and the run.
| M14 | M02C | |
|---|---|---|
| Shape | Wrap-around one-piece shield | Conventional frame with lenses |
| Weight | 52 g | About 41 g |
| Lens | Fixed shield in 4 colourways: smoke, blue mirror, ice-blue mirror, sunset-red mirror; not swappable | Choose sun, photochromic or clear when you order |
| Water rating | IPX4: splash, spray and rain | IP65: dust and water jets, not immersion |
| Camera | 8 MP Sony IMX219 | 8 MP Sony IMX219, dual stabilisation |
| Battery (rated) | 4 h listening / 7 h calls | 7 h listening / 4 h calls |
| Translation | 139 languages via the HeyCyan app | 40+ languages via the HeyCyan app |
| Price at checkout | $149 (listed $199) | $109 (listed $159) |
Prices checked 2026-10-09; checkout price may change. Two or more pairs in one order are 50% off all eyewear. Every model is on the full comparison page.
How to choose between them comes down to where you spend most of your training hours. If your week is built around long rides, the M14 is the closer match: the wrap shield is the shape riders already know, and its IPX4 rating covers rain and road spray. If most of your hours are on foot, the M02C is about 11 g lighter, it gives you a choice of three lenses, and its listening rating is 7 hours against 4. Some athletes will want both, one for each leg; because two or more pairs in one order are 50% off, a pair of each costs less together than the two single-pair prices added up. Whichever you choose, wear it on a few ordinary sessions first so you know how it sits before you rely on it for a long day.
4. M14 ($149 at checkout): the bike
The M14 is the frame we built for motion. It is a single wrap-around shield that sits close across your face in a riding position, with an 8 MP Sony IMX219 camera, open-ear speakers and microphones. It is rated IPX4, which covers rain and spray from the road.
- Battery. It is rated for 4 hours of listening and 7 hours of calls. That is the reverse of our other frames, so on a ride longer than four hours, plan to use the audio for part of it rather than all of it.
- Weight. At 52 g it is heavier than our 41 to 42 g frames. Compare that with the weight of the pair you race in now before deciding which to wear on a long day.
- Lens. The shield cannot be swapped. You choose one of the four colourways when you order, and that is the lens you keep. There is no clear option.

5. M02C ($109 at checkout): the run
The M02C is a conventional frame at about 41 g. It is rated IP65, meaning dust-tight and protected against water jets, which covers a run in the rain but not immersion. Its Sony IMX219 8 MP camera has dual stabilisation, which helps when you capture something mid-stride.
The battery is rated for 7 hours of listening and 4 hours of calls, so it comfortably covers a long run with a podcast. You choose the lens at checkout: sun, photochromic or clear. The lens options are listed as full tint (sun), adapts to light (photochromic) and daily wear (clear). Charging is magnetic. For running-specific advice, read smart glasses for running.
6. Never for the swim
Neither frame is rated for swimming. IPX4 on the M14 covers splash, spray and rain. IP65 on the M02C covers water jets, not immersion. A pool session, an open-water swim or the swim leg of a race is immersion, and saltwater is worse. Do not wear either pair in the water, and do not leave them where they will be soaked by a dripping wetsuit in transition.
The practical routine is to leave them with your bike gear, dry your hands and face, and put them on for the ride. If you want the details on water ratings, read are smart glasses waterproof?
7. Using them in training
- Long rides.Keep the volume low. Open-ear speakers leak some sound at high volume and won’t block out a windy road the way sealed earbuds do. Check the local rules on headphones while cycling where you ride.
- Brick sessions. Wear the same pair from the bike into the run so you practise the transition without fiddling with gear. If you train with the M14 on the bike and the M02C on the run, practise the swap too.
- Calls. The microphones let you take a call without stopping. On the M14 the call rating (7 h) is longer than the listening rating (4 h).
- Photos and clips. A touch on the temple starts a capture; nothing records unless you start it. Only touch the glasses when the road is clear and you are riding or running steadily, never on a descent or in traffic.
- Other people. On group rides, club runs and at the track, ask before you record. Recording people needs their consent where the law requires it, and clubs, pools, tracks and events may restrict cameras or audio devices. Check their rules.
- Getting files off. There is no display. Photos and clips go to the HeyCyan app on your phone, and the audio features need the phone nearby and connected.
A few things these frames will not do: none take prescription lenses, none has a display, and neither is a replacement for the race eyewear you already trust on race day.

Frequently asked questions
What are the best triathlon sunglasses?
For racing, a light, secure pair of plain sports sunglasses that stays put on the bike and the run does the job. Smart sunglasses are a different tool: they add open-ear audio and a camera for training. If you want that, the OXIVUE M14 wrap shield ($149 at checkout, 52 g, IPX4) suits the bike, and the M02C ($109 at checkout, about 41 g, IP65) suits the run. Neither is meant for the swim.
Can you listen to music during a triathlon?
Not in a USA Triathlon sanctioned race. Its rules page (checked October 9, 2026) lists playing music, making or receiving calls and taking photographs as distractive use of a communication device, which may result in disqualification. Other organisers set their own rules, so check your race's athlete guide. On race day, use smart sunglasses as plain sunglasses with the audio and camera off, or leave them in transition.
Can I swim in smart sunglasses?
No. The M14 is rated IPX4, which covers splash, spray and rain. The M02C is rated IP65, which covers dust and water jets, not immersion. Neither is rated for swimming, open water or saltwater, so leave them on your towel in transition and put them on for the bike. Our guide to whether smart glasses are waterproof explains what each rating means.
Should I wear sunglasses on the bike or the run in a triathlon?
That is a personal choice. What matters for smart sunglasses is fit and weight. The M14 is a wrap shield at 52 g, heavier than our 41 to 42 g frames, so try it on a long training ride before deciding to race in it. The M02C has a conventional frame shape and, at about 41 g, is about 11 g lighter than the M14.
Can I use open-ear audio on road rides?
Open-ear speakers sit outside your ears instead of sealing them like earbuds. They leak some sound at high volume and won't block out a windy road the way sealed earbuds do. Keep the volume low, and check the local rules on headphones while cycling where you ride. Your club or group ride may also have its own rule on audio devices.
Can I record my group ride or brick session?
Yes, a touch on the temple starts a photo or clip, so you capture only what you choose. When other people are in the frame, ask them first: recording people needs their consent where the law requires it, and clubs, tracks and pools may restrict cameras. Keep the camera for when the road is clear and never handle the glasses on a fast or technical section.
How fast do they ship, and what if something goes wrong?
US orders typically arrive in 5 to 9 business days and international orders in 9 to 14 business days, with free shipping from $99, so each pair here qualifies. No refunds except transit damage (replaced or refunded); faults are repaired or replaced under the 2-year warranty; change of mind and unmet expectations are not refundable.
What these frames won’t do
- No prescription lenses yet, on any model. If you need vision correction all day, these can't replace your glasses.
- No display. Nothing appears in your view; you hear answers and capture photos and video.
- Open-ear speakers leak some sound at high volume and won't block out a loud train or a windy road the way sealed earbuds do.
- Translation, music, calls and the assistant need your phone nearby and connected. Translation pauses after each sentence, and only you hear the translated audio; the other person reads the reply on your phone.
- M14: one-piece shield, so the lens can't be swapped for clear or photochromic.
- M14: IPX4 covers splash, spray and rain only, and at 52 g it is heavier than the 41–42 g frames.
- M02C: IP65 resists dust and water jets, not immersion. No swimming, no saltwater.
