Oura Ring 5 Launch Leaked for May 28: Slimmer Design, Bigger Sensors, New Colors

A leaked internal Oura document, first surfaced on Reddit and corroborated by FCC filings, reveals the Oura Ring 5 will be officially announced on May 28 with pre-orders opening the same day. Shipping begins June 4.

Design and Sensor Upgrades

The Ring 5 is smaller and lighter than the Ring 4, with a more curved outer surface and a seamless transition to the inner resin band. Under the hood, Oura has fitted significantly larger optical sensors with additional red and green LEDs, which should improve heart rate and SpO2 accuracy — the two areas where competitors like RingConn Gen 2 have been closing the gap.

New Color Options

Six colors are expected: Matte Black, Silver (brushed), Silver (glossy), Gold, Stealth, and a new Deep Rose replacing the outgoing Rose Gold. The size range stays the same at 6–13.

Charging Case

The Ring 5 ships with a size-specific charging case that holds enough battery for four full charges — up from three on the Ring 4 case.

Pricing Expectations

No official pricing yet, but analysts expect a $50 increase over the Ring 4's $349 starting price, landing around $399 — matching the Samsung Galaxy Ring. Oura's mandatory subscription ($5.99/month) remains a sticking point for cost-conscious buyers.

What This Means for Buyers

If you're eyeing an Oura Ring 4, the smartest move is to wait five days for the May 28 announcement. Ring 4 prices will likely drop once Ring 5 pre-orders open. Compare all options in our smart ring guide.
