Oura Ring Gen 4 FCC filing hints at ECG sensor, Ultra‑Wideband support and $399 US launch price later this year

Oura Health filed documents with the Federal Communications Commission revealing the upcoming Oura Ring Gen 4, expected to launch in the U.S. later this year with a $399 price tag. According to the filing, the new model will include Ultra-Wideband support and an updated sensor layout that may enable ECG monitoring and enhanced health tracking.

The filing includes a sample box label for an Oura Ring 4 Gold unit in size 15, providing tangible packaging details visible in the public record. The device is described as the successor to the Oura Ring 3, which has been on the market since October 2021, and the filing signals Oura Health’s preparation for U.S. regulatory clearance under its brand.

The Federal Communications Commission filing identifies the device as Oura Ring 4 with the model number OA11 and confirms it is undergoing certification review in the United States, according to documents first reported by Android Authority.

While the FCC materials confirm the ring retains sensors for heart rate, respiration rate, body temperature, movement, and Bluetooth Low Energy (BLE) connectivity, the filing does not explicitly mention new sensors or confirm the addition of an electrocardiogram (ECG) sensor, according to the filing summary cited by Android Authority. Photos of the ring’s interior included in the filing show a different sensor layout compared to previous generations, suggesting possible hardware changes, but these changes are not detailed in the public documents. Oura’s own support page for Ring 4 describes the device as built around a “Smart Sensing” system designed to adapt to the finger for continuous data collection day and night, though it does not explicitly mention ECG functionality.

Additional teardown-style analysis shared on social media reveals the interior contains optical sensors, a curved battery, an antenna, and a flexible printed circuit board (PCB), indicating a tightly integrated hardware design. Despite this, the available FCC documentation and related materials do not independently verify the presence of an ECG sensor, and third-party speculation about expanded biometric capabilities remains unconfirmed.

Reports have linked Oura’s acquisition of Proxy, a company specializing in contactless payment technology, to the possibility that the Oura Ring 4 could support near-field communication (NFC) or payment features. Some commentary sources have speculated that the ring might enable Apple Pay-style contactless payments and virtual cards, but these claims are based on expectation rather than confirmed FCC disclosures. The filing only verifies continued BLE support, and Ultra-Wideband (UWB) connectivity, while mentioned in some reports, is not directly confirmed by the FCC documents or Oura’s official communications.

Regarding pricing, the suggested $399 U.S. launch price has not been confirmed by Oura or reflected in the FCC filing or official support pages. None of the publicly available sources provide an official retail price, and the figure appears to originate from leaks or rumors circulating alongside the filing coverage. The timing of the launch is described by some reports as “relatively imminent,” with an official unveiling likely within weeks or a couple of months following FCC approval, but no firm launch date has been announced by Oura.

Oura’s support page remains the most authoritative source confirming the product name and its Smart Sensing positioning. The FCC ID record for OA11 confirms the device’s presence in the U.S. certification ecosystem but does not substantiate detailed feature claims such as ECG or UWB. Additional compliance pages for related hardware components indicate ongoing regulatory readiness by Oura.

The Oura Ring 3, introduced in October 2021, set a precedent for the company’s wearable health tracking, and the Gen 4 model appears to continue this trajectory with refinements in sensor layout and hardware integration. The public documentation and ongoing media coverage suggest that Oura is preparing for a U.S. market launch later this year, though specifics on features and pricing remain subject to official confirmation.
