I’ve only worn it for two days. Already, my feed is flooded with DMs. People want the referral link. They want the sizing kit. Mostly, it’s women asking which color I picked.
Most of these products just scream “gadgets”
— Me
I’m a wearables reviewer. I get “I want one” comments often. But the Ring 5 triggered a specific kind of buying panic I rarely see. And honestly? I get it.
When the original Oura dropped in 2015 it was chunky. Heavy. Like a championship ring you win for crushing the competition. It swallowed your finger base whole. Now? The Ring 5 is $400, sure. That’s $50 more than the Gen 4. But it’s also invisible. It looks like jewelry. Just jewelry. Not tech disguised as jewelry. Real gold. Not the plastic-coated “costume” look from before.
Slimmer. Lighter. Actually Wearable.
It’s 6mm wide. 2mm thick. Oura claims it’s 40% smaller than the last model. I put it next to the Gen 4 and an Ultrahuman Pro ring. The difference is glaring.
I took a gamble. Ordered a size smaller than usual. My Ring 4 (a size 9) lived on my middle finger because anything smaller hurt. This one? Size 8 on my ring finger. Fits perfectly. I’d still suggest using the sizing kit though. Don’t be me. Be smarter.
The comfort win came while washing my face. Old rings drag against your cheeks. You feel every scrape. The Ring 5 tucks into the fold of my hand. Disappears. I suspect it will behave itself at the gym too. Previous models pinched during weights. This one shouldn’t.
My Gen 4 is scratched to hell from lifting. The new ring promises better scratch resistance. Too early to declare victory but after a Pilates session and two days of wear it’s still pristine. No scars yet. That’s a good start.
Does it work? Mostly.
Setup was instant. I already had the account. Just pair. Go. Oura lets you keep both rings active. I disconnected the old one to isolate the new sensors.
They reduced the sensor pathways from 18 to 16? Wait. Let me check the brief. Ah, 12 pathways. They made them powerful LEDs though. Better signal. Better accuracy for all skin tones. The claim.
The workout detection? Mixed bag.
I did a 30-minute Pilates session at night. Heart rate hit 138 bpm (verified by Apple Watch). Oura? Blank. Nothing. It detected two separate “housework” sessions that were significantly less intense. Frustrating? Yes. Is it the end of the world? Not yet. You have to train it. Tag your workouts. It gets smarter. I’m giving it benefit of the doubt.
But the run?
Four miles. No phone. No watch. Just the ring. It caught the start. Caught the end. Timing down to the minute. No GPS so no distance map but the heart rate? Stunning. 171 bpm max. My Apple Watch (tethered to a chest strap for accuracy) said 173. Identical average. For a ring? That’s impressive.
Sleep tracking? Spot on.
Both nights logged exactly 6.5 hours. Woke me up when I tossed. Captured the interruptions. My readiness score says I’m an “A-” today. My brain says otherwise. Foggy. Tired. The algorithm lies. Or I just need coffee.
Temperature data remains the killer app. Correlates with cycle data. Predicts ovulation. Accurately. If you track hormones this feature alone might justify the subscription. It also checks for Afib and sleep apnea markers but I need a full week of data for those to unlock. Patience is required.
Battery life? Promising.
Two nights sleep. One outdoor run. 80% remaining.
Oura promises six to nine days. Competitors like Ultrahuman or Whoop push toward two weeks. So Oura is falling behind there? Maybe. But one extra day over the Gen 4 while losing physical size is a decent trade-off. I won’t complain if it lasts six.
The verdict (so far)
The best thing about the Ring 5 has nothing to do with metrics.
It’s the feeling. On the finger.
I stopped checking my app every ten minutes. I just wear it. It’s stylish. It’s quiet. It doesn’t demand attention. The full review will tell us if the long-term health data holds up but for the first 48 hours the vibe is right.
It finally feels like something you want to wear. Not something you endure.
Whether the sensors stay as sharp when I’m tired as when I’m fresh? That remains to be seen. I’ll be watching the battery drop closely too.
