Oura Ring 5 Leak Confirms Launch Date, Pricing and New Specs

The latest leak, now verified by Winfuture, gives us a clear picture of the upcoming Oura Ring 5. The company plans an official unveiling on Thursday, May 28, with shipments slated to start June 4. Below we unpack the hardware changes, pricing structure and what the upgrade means for existing Oura users and health‑tracking enthusiasts.

What’s new?

Feature	Oura Ring 4	Oura Ring 5
Body diameter	8.0 mm	7.0 mm (claimed world’s smallest smart ring)
Battery life	~5 days	~7 days
Water resistance	50 m	100 m
Sensors	PPG HR, SpO₂, temperature	Larger PPG, SpO₂, temperature sensors (no new sensor tech)
Charging	Magnetic dock, USB‑C cable	Same dock, optional travel case (sold separately)
Price (base)	€399 (US $349)	€429
Premium finishes	Silver, black, gold, rose gold (polished)	Added matte silver/black, price up to €529
Subscription	€5.99 / month for full metrics	Same price, required for >50 health metrics

Size and comfort

The most visible change is the 7 mm ring profile, a full millimeter smaller than its predecessor. The slimmer silhouette should reduce the “pinch” feeling many users reported after a few hours of wear, especially on smaller fingers. The design still uses a polished or matte finish, with color options expanding to matte black and matte silver for a more understated look.

Battery and durability

Oura promises a one‑week runtime on a single charge, up from roughly five days on the Ring 4. The improvement likely stems from a combination of a slightly larger internal battery and the more efficient sensor layout. Water resistance doubles to 100 m, meaning the ring can survive swimming sessions and shallow diving without a second‑thought.

Sensors and data quality

The leaked images show the internal photoplethysmography (PPG) and SpO₂ modules are physically larger. While Oura isn’t introducing brand‑new sensor technology, the increased sensor area should capture more photons, reducing noise and potentially delivering more accurate heart‑rate and oxygen‑saturation readings, especially during high‑intensity workouts.

Charging accessories

The Ring 5 ships with a magnetic dock and a USB‑C charging cable – a welcome shift from the proprietary USB‑A cable used on the Ring 4. For travelers, a separate charging case is available, but it adds to the overall cost.

How it compares to the Ring 4 and competitors

Pricing

The base model starts at €429, about €30 higher than the Ring 4’s launch price. Premium finishes push the price to €529, positioning the Ring 5 in the same bracket as the Whoop 4.0 and Fitbit Sense 2 when you factor in the mandatory subscription.

Feature set

Both Oura and its rivals require a subscription for full analytics. Oura’s subscription (currently €5.99 / month) unlocks:

• Over 50 health metrics, including sleep stages, HRV, respiratory rate, and a new "symptom radar" that flags early signs of illness.
• Continuous heart‑rate monitoring, SpO₂, and skin‑temperature trends.
• Integrated stress and menstrual‑cycle tracking.

Compared to Whoop, which focuses heavily on strain and recovery, Oura retains its sleep‑centric reputation while adding more granular cardio data. The Fitbit Sense 2 offers similar sensor suites but lacks the same depth of sleep analysis that Oura’s algorithms provide.

Subscription value

The €5.99 monthly fee translates to roughly €71 per year. If you consider the Ring 5’s price plus a year of subscription, you’re looking at ~€500 total for a device that promises a full week of battery life and a more comfortable fit. For users who already own a Ring 4, the upgrade may feel incremental unless the larger sensors deliver noticeably better data.

Who should consider the Oura Ring 5?

User type	Why the Ring 5 makes sense
Sleep enthusiasts	Improved comfort for all‑night wear and a week‑long battery reduce interruptions.
Athletes & active users	Larger sensors may yield tighter HR and SpO₂ readings during high‑intensity sessions.
Frequent swimmers	100 m water resistance eliminates the need for a separate waterproof tracker.
Existing Oura owners	If you’re dissatisfied with the Ring 4’s bulk or battery life, the slimmer, longer‑lasting Ring 5 is a logical upgrade.
Budget‑conscious buyers	The price jump and required subscription may steer you toward cheaper alternatives like the Amazfit Band 8 or Xiaomi Mi Band 8.

Bottom line

The Oura Ring 5 appears to be an evolutionary step rather than a radical redesign. Its slimmer profile, extended battery life and deeper water resistance address the most common complaints about the Ring 4. The larger sensor package could translate into marginally better data, but the core algorithms remain unchanged. Pricing sits comfortably within the premium health‑tracker market, though the mandatory subscription adds a recurring cost that may deter price‑sensitive shoppers.

If you value a discreet, comfortable ring that can be worn 24/7 and you’re already comfortable with Oura’s ecosystem, the Ring 5 is a worthwhile upgrade. For newcomers, the decision will hinge on whether you prefer a ring‑form factor over a wrist‑based device and whether you’re prepared to pay the subscription fee for the full suite of metrics.
