If you’ve been eyeing that space on your finger for something a bit more tech-savvy, Oura has just dropped their latest hardware. The Oura Ring 5 is officially the smallest smart ring the company has ever produced. They’ve managed to shave off 40% of the volume compared to its predecessor. It’s sleeker and way less clunky than the tech wearables we’ve become accustomed to lately.

Getting this level of miniaturization usually involves trade-offs, but the manufacturer is standing firm on the battery stats. They claim you’ll still get that reliable “week-long” performance between charges. For those who travel often and hate carrying extra cables, the optional charging case is making a return. It keeps everything organized while you’re on the move.

Where Symptom Radar helped members recognize when something felt off, Health Radar goes further: continuously monitoring key biometric signals in the background to surface patterns members should pay attention to, before they become problems.

Beyond just getting smaller, the device is getting a brain boost. The old Symptom Radar feature, which would tell you if you were about to catch a cold by checking your body temperature, is evolving into Health Radar. Instead of waiting for a sniffle to appear, the new software looks at long-term patterns in your biometric data to spot health dips before you even feel them. This proactive tech makes these gadgets popular for data nerds who love tracking their sleep and recovery scores.

Durability is a core concern when you shrink electronics this much, and ŌURA says this is their most scratch-resistant build to date. Since the dimensions have shifted so drastically, the company is explicitly telling everyone—even if you’ve worn their rings for years—to use the new sizing kit before you pull the trigger on a purchase. Ordering the wrong size and having to wait for a return is a headache nobody needs.

Now, about the price. If you want the standard black or silver finish, you’re looking at a $399 starting point. That’s a $50 bump over the previous generation. If you prefer the more premium finishes like brushed silver, stealth, gold, or the brand-new deep rose, the price climbs to $499. That represents a $100 increase for some models. It aligns with the pricing they set for their previous ceramic-finish offerings.

This trend of making tech devices smaller and more discreet is catching on. It’s a smart move for users who prefer a minimalist vibe. Some people love a gadget that screams "look at my tech," but others want a health tracker that looks like a basic wedding band. This ring sits firmly in the latter category. It’s lowkey impressive how much sensor tech they’ve stuffed into such a tiny piece of metal.

Shipping for these pre-orders kicks off on June 4. If you’re already part of the Oura ecosystem, you know the monthly subscription requirement stays in play for the full feature set. Whether the new Health Radar and the 40% size reduction justify that extra $50 to $100 for you will depend on how much you value those tiny, granular insights into your body's performance.
