Which pair of “smart” sports glasses puts real numbers in front of your eyes while you move, and which ones are doing something else entirely? Only the ENGO 2 ($349.95) does the first job — a MicroOLED heads-up display that shows pace, heart rate, and power pulled live from your paired Garmin or Apple Watch. Oakley Meta Vanguard ($499) and Solos AirGo 3 (from $199) are different tools wearing a similar shape: a hands-free camera with an AI assistant, and an audio-first AI/translation assistant, respectively — neither puts a real-time data screen in your line of sight at all.
Do Any of These Smart Glasses Show My Workout Data in Real Time?
Only one does: the ENGO 2. It’s built around a genuine MicroOLED heads-up display using ActiveLook Light AR technology, positioned in your line of sight without blocking your view of the road or trail. It pairs with Garmin devices, Apple Watch, iOS, and Android to pull and display more than 40 customizable metrics live — pace, heart rate, power, cadence, and running dynamics among them — with gesture control letting you switch screens mid-stride without touching a button. At 36 grams it’s the lightest of the three, rated for up to 12 hours of battery life per Engo’s own product page, and comes in Solar, Photochromic, and high-contrast Vive lens options across two frame sizes. It has no camera, AI assistant, or built-in audio — it’s a single-purpose tool for seeing your existing device’s data without looking down.
Oakley Meta Vanguard integrates with Garmin (voice-querying your watch’s stats) and Strava (overlaying distance, elevation, and heart rate onto your photos and videos afterward), and Solos AirGo 3’s onboard “AI Coach” tracks steps and calories from its own motion sensors — but neither shows a persistent, real-time number in your lens while you’re mid-effort the way ENGO 2 does.
Which One Is Really a Camera First, Everything Else Second?
Oakley Meta Vanguard, without much competition. Priced at $499, it centers on a 12MP ultra-wide camera positioned above the nosebridge with video stabilization, hyperlapse, and slow-motion capture. Meta AI handles voice commands and a customizable action button enables hands-free control. Per Oakley’s own product page, the glasses carry an IP67 rating for sweat, dust, and weather resistance. Battery life runs up to roughly 9 hours with typical use, dropping to around 6 with continuous audio playback. Swappable lenses cost extra, and no prescription lens option is currently available. It’s the right choice if what you want is hands-free content — photos and video with data-rich overlays added afterward — rather than something to glance at mid-effort.
Which One Is Built for Voice AI, Translation, and Basic Coaching Instead of a Screen?
Solos AirGo 3, the cheapest entry point of the three at $199 for the sport-focused Helium frame (Argon eyeglasses and Xeon sunglasses also available). It’s built around audio and AI rather than a display: SolosChat, a ChatGPT-powered voice assistant for hands-free queries, plus SolosTranslate, which Solos’ current product page lists as supporting real-time translation across 10 languages — fewer than some older marketing mentions of this line, so we’re citing the number on the live spec sheet rather than an older figure. Its onboard “AI Coach” tracks steps and calories using built-in motion sensors and offers posture feedback — self-contained sensor data, not the live pace/heart-rate/power feed ENGO 2 pulls from an external watch. Solos rates battery life at up to 10 hours of music streaming or 7 hours of calls, with an IP67 splash-proof rating, and the modular design allows frame swapping with prescription-friendly options.
How Do the Three Compare on Features Per Dollar?
Sticker price alone makes ENGO 2 look mid-tier and Solos AirGo 3 look like the deal. Counting actual features tells a more complete story. We defined seven distinct, independently confirmable features — live in-lens HUD, built-in camera, AI voice assistant, real-time translation, onboard fitness-sensor tracking (no paired device required), a confirmed IP water/dust rating, and manufacturer-rated battery life of 10+ hours — counted how many each product has per its own current spec page, and divided that count into the price.
| ENGO 2 | Oakley Meta Vanguard | Solos AirGo 3 | |
|---|---|---|---|
| Live in-lens HUD | Yes | No | No |
| Built-in camera | No | Yes | No |
| AI voice assistant | No | Yes | Yes |
| Real-time translation | No | No | Yes |
| Onboard fitness sensors (no paired device) | No | No | Yes |
| Confirmed IP water/dust rating | Not published | Yes (IP67) | Yes (IP67) |
| Battery ≥ 10 hrs (primary use) | Yes (12 hrs) | No (~6–9 hrs) | Yes (10 hrs) |
| Feature count | 2 | 3 | 5 |
| Price | $349.95 | $499 | $199 |
| Price ÷ features = cost per feature | $349.95 ÷ 2 = $174.98 | $499 ÷ 3 = $166.33 | $199 ÷ 5 = $39.80 |

Read this table carefully: it treats every feature as equally weighted, which real buying decisions don’t. ENGO 2’s two features cost the most per feature on paper, but one of them — a genuine live HUD — is the entire reason a data-focused runner or cyclist would consider this category at all. Solos AirGo 3 wins the arithmetic by packing in AI, translation, and basic sensor tracking cheaply, but none of those features do the specific job ENGO 2 does. Feature density per dollar is a useful check on marketing, not a substitute for matching the device to what you actually want it to do.
Which Should You Buy for Your Sport?
Buy the ENGO 2 if you specifically want to see your live pace, heart rate, or power without glancing at a watch or bike computer — it’s the only one of these three built for that exact job. Buy the Oakley Meta Vanguard if capturing hands-free photo and video content of your rides or runs, with activity data overlaid afterward, matters more than a live display. Buy the Solos AirGo 3 if you want the cheapest entry point into an AI voice assistant, real-time translation, and basic step/calorie tracking, and don’t need serious live training metrics or a camera.
How We Compared These Smart Glasses
PicksWeTrust did not physically test these three products for this comparison. Pricing and specs were verified against each brand’s current official product pages — Engo, Oakley/Meta, and Solos — cross-referenced with 2026 hands-on coverage from Engadget and Laptop Mag. The translation-language and battery figures for Solos AirGo 3 were checked directly against the brand’s current Helium collection spec page rather than reused from an earlier version of this comparison. More on our process is on our editorial standards page.

Common Questions About Smart Sports Glasses
Which smart glasses show my workout data while I’m exercising?
Only the ENGO 2, using a genuine MicroOLED heads-up display that pulls live metrics like pace, heart rate, and power from a paired Garmin or Apple Watch. Neither Oakley Meta Vanguard nor Solos AirGo 3 offers a real-time in-lens data display.
Does Oakley Meta Vanguard show my Strava or Garmin data while I ride?
Not live. It integrates with Garmin and Strava to overlay activity data like distance, elevation, and heart rate onto photos and video you’ve already captured, and lets you voice-query watch stats through Meta AI, but there’s no persistent in-lens display like ENGO 2’s.
How many languages does Solos AirGo 3 translate in real time?
Ten, according to the current product spec page for the AirGo 3 Helium collection. Some earlier coverage of this product line cited a higher figure; we’re reporting the number listed on Solos’ own live spec sheet.
Which of these has the longest battery life?
The ENGO 2, rated up to 12 hours per its own product page, ahead of Solos AirGo 3’s 10 hours of music streaming and Oakley Meta Vanguard’s roughly 6–9 hours depending on camera and audio use.
Do any of these three have a camera?
Only Oakley Meta Vanguard, with a 12MP ultra-wide camera for photo and video capture, including hyperlapse and slow-motion modes. Neither ENGO 2 nor Solos AirGo 3 includes a camera.
