Product Info

For sale is a pre-owned Oura Ring 4 smart ring finished in polished Gold, size 8, bundled exclusively with its matching desktop charging dock. Hardware performance tracking diagnostics and automated interface syncing logs register the following technical parameters:

  • Internal Logic System Integrity: The underlying operational sensor cluster is 100% fully functional. Bench diagnostics verify that the upgraded Smart Sensing technology, featuring fully recessed interior sensor paths and an all-titanium inner lining, captures bio-telemetry curves flawlessly. The ring establishes high-speed Bluetooth communication with the Oura mobile app environment, completes firm data package sync routines, and accepts firmware updates over-the-air. The internal power cell holds a normal multi-day continuous runtime discharge curve.
  • Heavy Exterior Scratching: The exterior aesthetics display heavy cosmetic wear and visible physical abrasions. The outer polished gold protective finish layer shows deep surface scratches, uniform scuffing, and distinct rubbing wear patterns along the perimeter borders from standard daily contact with surfaces. The interior titanium framework is completely smooth, structural, and comfortable against skin profiles with no structural distortions.
  • Charging Base & USB Cord Notice: This listing includes the authentic size-matched proprietary circular Oura Ring 4 desktop charging base. Please take note that **the USB Type-C power cord is completely absent from this package**. To power the cradle and charge the ring, you will need to connect the included dock to a standard USB-C cable hooked up to a 5V USB power source (Note: Generation 3 chargers are not compatible with Oura Ring 4 modules).
  • Account Initialization Status: The unit has been successfully cleared of historical personal telemetry tracks via full system settings wipe, unlinked from active subscriber portals, and prepared for fresh user configuration profiling.

FULLY FUNCTIONAL CORE HARDWARE MODULE. Structural titanium frames have never been compromised. This listing tracks strictly as the SMART RING MODULE WITH DOCK ONLY (no cable, retail boxes, or setup manuals). OUT OF WARRANTY.
