Oura Ring 5 Review: Still the Smart Ring to Beat

Oura Ring 5 评测：依然是目前最值得入手的智能戒指

WIRED 优点： 设计更小巧、更舒适。健身功能得到改进，包括实时活动（Live Activity）功能、心率监测器支持，以及更可靠的自动运动检测。新增了贴心的隐私保护功能。支持无缝多戒指连接。 缺点： “症状雷达”（Symptom Radar）的预测能力仍未达到 Oura 所宣称的水平。订阅制依然让人感觉是强制性的。

Since establishing the smart ring category in 2015, Oura has spent the past decade maintaining its leadership as competitors like Ultrahuman, RingConn, and Samsung entered the market. The Oura Ring 5 doesn’t attempt to overhaul what already works. Instead, it offers a careful refinement: smaller, more comfortable, and equipped with a smarter software experience that emphasizes AI-driven health coaching. After three weeks of wearing it, I consider it the best smart ring Oura has produced, though Ring 4 owners might find it hard to justify upgrading. 自 2015 年开创智能戒指品类以来，Oura 在过去十年中一直保持着行业领先地位，尽管 Ultrahuman、RingConn 和三星等竞争对手相继进入市场。Oura Ring 5 并没有试图推翻已经成熟的设计，而是进行了精心的改良：体积更小、佩戴更舒适，并配备了更智能的软件体验，重点强化了 AI 驱动的健康指导。在佩戴三周后，我认为这是 Oura 目前为止推出的最好的智能戒指，尽管对于 Ring 4 的用户来说，升级的必要性可能并不明显。

A Sleeker Ring

更精致的戒指

Sometimes I forget I’m wearing the Oura Ring 5. At 6.09 mm wide and 2.28 mm thick, it’s approximately 40 percent smaller than the Ring 4, and Oura says it’s the smallest smart ring on the market. After sleeping with it every night, wearing it through workdays, and keeping it on for most workouts, I found it way more comfortable than previous generations. 有时我甚至会忘记自己戴着 Oura Ring 5。它的宽度为 6.09 毫米，厚度为 2.28 毫米，比 Ring 4 小了约 40%，Oura 声称它是目前市面上最小的智能戒指。在每晚佩戴入睡、工作日全天佩戴以及大部分运动时佩戴后，我发现它比前几代产品舒适得多。

Fortunately, the slimmer build doesn’t sacrifice durability. The titanium exterior now has a tougher physical vapor deposition coating, and the ring retains its IP68 rating and 100-meter water resistance. After three weeks of daily wear, mine still looks surprisingly clean. A few hairline marks have started to appear, but they’re far subtler than the scratches my Ring 4 picked up within its first week. 幸运的是，更纤薄的机身并没有牺牲耐用性。钛金属外壳现在采用了更坚固的物理气相沉积（PVD）涂层，戒指依然保持了 IP68 级防尘防水性能和 100 米防水深度。经过三周的日常佩戴，我的戒指看起来依然非常干净。虽然开始出现了一些细微的划痕，但比我的 Ring 4 在第一周内产生的划痕要隐蔽得多。

Setup remains straightforward, and pairing took just a few seconds. Oura has trimmed the size range: the Ring 5 comes in sizes 6 through 13, compared to the Ring 4’s 4 through 15. Existing Oura owners should still order the updated sizing kit before buying. Although I stuck with the same size as my Ring 4, the Ring 5 fit more snugly, and I could easily see some people needing to size up. 设置过程依然简单直接，配对仅需几秒钟。Oura 缩减了尺寸范围：Ring 5 提供 6 到 13 号，而 Ring 4 为 4 到 15 号。现有的 Oura 用户在购买前仍应订购更新后的尺寸测量套件。虽然我选择了与 Ring 4 相同的尺寸，但 Ring 5 的佩戴感更紧凑，我完全可以预见有些人可能需要选择大一号。

Despite Oura’s hardware upgrades, I didn’t notice dramatic differences in the data itself. My overnight resting heart rate, heart rate variability, and activity tracking closely match what I was already seeing on the Ring 4. That’s less of a criticism than it sounds, considering the Ring 4 was already among the smartest rings I’ve tested. That said, Oura attributes any accuracy improvements to LEDs that are four times more powerful, redesigned sensors that sit closer to your skin, and 12 independent signal pathways intended to improve readings across different finger shapes and skin tones. 尽管 Oura 进行了硬件升级，但我并没有注意到数据本身有显著差异。我的夜间静息心率、心率变异性和活动追踪数据与我在 Ring 4 上看到的结果非常吻合。考虑到 Ring 4 本身就是我测试过的最智能的戒指之一，这算不上什么批评。话虽如此，Oura 将准确性的提升归功于功率提升四倍的 LED 灯、更贴合皮肤的重新设计传感器，以及旨在改善不同手指形状和肤色读数的 12 条独立信号通路。

Battery life was also a modest improvement, averaging between six and nine days per charge. This slightly exceeds its predecessor’s five- to eight-day estimate. Oura also released a new portable Charging Case ($99), which stores enough power for roughly five full charges. A physical button lets you check charging and pairing status, and it’s compatible with the new Locate feature, which lets you find both your ring and charging case in the Oura app. It’s a nice travel accessory, though not an essential purchase for most people. 电池续航也有小幅提升，平均每次充电可使用 6 到 9 天。这略高于前代产品 5 到 8 天的预估。Oura 还发布了一款新的便携式充电盒（售价 99 美元），可存储约五次完整充电的电量。通过一个物理按钮，你可以查看充电和配对状态，它还兼容新的“定位”（Locate）功能，让你能在 Oura App 中找到戒指和充电盒。这是一个不错的旅行配件，但对大多数人来说并非必需品。

Smarter Insights

更智能的洞察

The biggest changes are in the app, but earlier generations also benefit from the upgrades. Oura is increasingly positioning the Ring 5 as a proactive health platform powered by AI. Much of that strategy centers on Oura Advisor, the company’s large-language-model-powered assistant introduced last year, alongside new predictive health features that aim to tell you what’s happening in your body before you notice it yourself. Oura also partnered with Counsel Health to expand Advisor beyond wellness coaching. Through the app, members can ask health questions, receive personalized guidance informed by their biometric data, and connect with licensed health care professionals without leaving the app. 最大的变化在于 App，但前几代产品也能从这些升级中受益。Oura 正日益将 Ring 5 定位为一个由 AI 驱动的主动健康平台。这一战略的核心很大程度上在于去年推出的、基于大语言模型的助手 Oura Advisor，以及旨在让你在察觉身体变化前就发出预警的全新预测性健康功能。Oura 还与 Counsel Health 合作，将 Advisor 的功能扩展到健康指导之外。通过 App，会员可以咨询健康问题，获取基于生物识别数据的个性化建议，并无需离开 App 即可联系持证医疗专业人员。

Fitness tracking has also become more capable. The new Live Activity feature lets me start workouts from my phone and view pace, distance, and heart rate on lock-screen widgets. During runs, I appreciated being able to glance at these metrics without unlocking my phone. It’s a small improvement, but it makes Oura feel more like an active fitness tracker. Automatic Activity Detection also appears more reliable. The Ring 5 consistently recognized my walks and even caught Pilates sessions that earlier generations often missed. 健身追踪功能也变得更强大。新的“实时活动”（Live Activity）功能允许我通过手机启动锻炼，并在锁屏小组件上查看配速、距离和心率。在跑步时，我非常喜欢无需解锁手机就能查看这些指标。这是一个小小的改进，但让 Oura 感觉更像是一款主动式的健身追踪器。自动活动检测似乎也更可靠了。Ring 5 能够稳定地识别我的步行，甚至捕捉到了前几代产品经常漏掉的普拉提课程。

I also appreciated Oura’s new ability to pair with third-party heart rate monitors via Bluetooth. For workouts like strength training, where wearing a ring isn’t comfortable, I could leave my Oura in my gym bag without losing heart rate data. This solves one of my biggest long-standing complaints about smart rings, but it does still require buying another sensor. 我也很欣赏 Oura 新增的通过蓝牙与第三方心率监测器配对的功能。对于力量训练等佩戴戒指不舒适的运动，我可以把 Oura 放在健身包里，而不会丢失心率数据。这解决了长期以来我对智能戒指最大的不满之一，但它确实仍需要额外购买一个传感器。

Sleep remains Oura’s biggest strength. Over three weeks of testing, it consistently produced some of the most believable data I’ve seen from any wearable. Nights when I stayed up too late or woke up multiple times were accurately reflected in both my Sleep and Readiness Scores. Those scores also almost always aligned with how I actually felt before opening the app. 睡眠监测依然是 Oura 最强的优势。在三周的测试中，它始终如一地提供了我所见过的可穿戴设备中最可信的数据。我熬夜太晚或多次醒来的夜晚，都能在我的睡眠评分和准备度评分中得到准确反映。这些评分几乎总是与我在打开 App 前的实际感受相吻合。

Symptom Radar still isn’t perfect. I came down with the flu during testing, and while the Ring 5 eventually flagged subtle physiological changes, it happened about a day after I’d realized I was getting sick. That’s roughly in line with my experience using the Ring 4, despite Oura’s claims that Symptom Radar has improved. “症状雷达”依然不够完美。我在测试期间患上了流感，虽然 Ring 5 最终标记出了细微的生理变化，但那是在我意识到自己生病大约一天之后。尽管 Oura 声称“症状雷达”有所改进，但这与我使用 Ring 4 的体验大致相同。

The new Health Radar includes two new health-monitoring tools: Blood Pressure Signals looks for biometric patterns that may correlate with cardiovascular strain, and Nighttime Breathing provides a rolling 30-day analysis of breathing disturbances during sleep. My Ring 5 hasn’t detected any significant breathing disruptions, which lines up with the rest. 新的“健康雷达”（Health Radar）包含两项新的健康监测工具：“血压信号”（Blood Pressure Signals）用于寻找可能与心血管压力相关的生物识别模式；“夜间呼吸”（Nighttime Breathing）则提供睡眠期间呼吸紊乱的 30 天滚动分析。我的 Ring 5 没有检测到任何明显的呼吸紊乱，这与我的实际情况相符。
