(checked 2026-10-10)7,373 ratings on the Gold, size 10 listing (13% 1-star, 6% 2-star).

The $299 titanium step-up from the Gen 2 Air, adding sleep apnea monitoring, VO2 max and a charging case that RingConn says keeps it going 150-plus days. Experts mention it mostly as an alternative rather than a top pick. About 1 in 5 Amazon ratings are 1 or 2 stars, often about batteries that stop holding a charge.

Subscription: None (WIRED, Tom's Guide)

Top complaints

  • Battery stops holding a charge; rings stop working

    Amazon's review summary says some owners report the battery stops holding a charge and the ring stops working after a few months, and calls durability a concern.

  • Few workout modes

    Tom's Guide notes it tracks a relatively modest number of activities, such as running, cycling and yoga.

  • Mostly a secondary recommendation

    WIRED lists it as an honorable mention, mainly $100 more than the Gen 2 Air for sleep apnea monitoring, VO2 max and titanium. Amazon owners are split on whether it's worth the price.

What owners love

Good for
  • Sleep apnea monitoring without a subscription
  • Long battery with a pocketable charging case
  • A titanium ring for less than Oura

Scores (tap for why)

What experts say

  • WIRED: Honorable mention: still relatively affordable and subscription-free; adds sleep apnea monitoring, VO2 max and titanium over the Gen 2 Air.
  • Tom's Guide (hands-on): January 2025 hands-on: potentially beats the Oura Ring 4 on sleep apnea detection, thinner design and charging case; battery claims weren't yet tested.

If that catch is a deal-breaker

Highly ranked smart rings whose biggest complaint is something else.

#1 in smart ringsOura Ring 5

The top pick at WIRED, PCMag, Tom's Guide, ZDNET and CNET: 40% smaller than the Ring 4, comfortable, with accurate sleep and stress tracking and about 10 days of battery in PCMag's test. The catch is the $399 price plus a $6-a-month membership that WIRED says still feels mandatory, and sizes stop at 6-13.

Its catch: membership on top of a $399 ring#2 in smart ringsOura Ring 4

Still sold alongside the Ring 5 and getting the same software updates, it's PCMag's Best Value pick and Wirecutter's top sleep tracker. But it's bulkier than the Ring 5, needs the same membership, and 1 in 5 Amazon ratings are 1 or 2 stars, often over battery life and rings that fail within a year.

Its catch: battery and reliability problems#3 in smart ringsUltrahuman Ring Pro

Ultrahuman's redesigned ring is sold in the US at $479 after the Ring Air was blocked over an Oura patent (CNET, Engadget). It offers 10+ days of battery and a feature-rich charging case. Engadget rates it 8.9/10, but ZDNET gives it 3/5, calling it chunky and more expensive than the Oura Ring 5.

Its catch: chunky, with protruding sensors
