Has the Oura Ring 5 Approached the "Perfect Smart Ring"? Expectations and Discontent Revealed Through Social Media Reactions

Smartwatches are convenient. They allow you to check notifications, record exercise, and monitor heart rate and sleep. However, this convenience comes at the cost of the feeling of "always wearing a screen." The presence as a wristwatch is strong, and some people find it bothersome while sleeping. Some feel it doesn't match their fashion sense.

In contrast, there are smart rings. These ring-shaped wearable devices do not have a display and do not rush the user with notifications. They look more like accessories and focus on quietly recording the body's condition. The Oura Ring is a prime example, and the newly released Oura Ring 5 signifies that this category has progressed to the next stage.

The point emphasized in ZDNET's review is not flashy new features but "comfort." The Oura Ring 5 is significantly more compact compared to the Oura Ring 4, greatly reducing the discomfort when worn on the finger. To sum up the review in one sentence, "The biggest upgrade of the Oura Ring 5 is that you can forget you're wearing it."

At first glance, this may seem like a modest evolution. However, comfort is not just an added value for wearable devices. For a device worn daily, even during sleep, a slight thickness, weight, or difficulty in opening fingers can determine whether it continues to be used. The essence of the Oura Ring 5 lies in its evolution towards reducing its presence in daily life, rather than the numbers on a spec sheet.

What the 40% Reduction in Size Means

According to official Oura information, the Oura Ring 5 claims to be the "world's smallest smart ring," capable of acquiring over 50 health metrics at your fingertips. It is smaller, thinner, and lighter than the previous model, with a battery that lasts 6 to 9 days depending on usage and size. Made of titanium, it is waterproof up to 100m and complies with IP68 waterproof and dustproof standards.

In Japan, the price is set at 65,800 yen for silver and black, and 81,800 yen for finishes like gold, deep rose, brushed silver, and stealth. Clearly, it is a premium product among smart rings and not cheap compared to smartwatches.

Nevertheless, the Oura Ring 5 is attracting attention because it already has a track record as a health tracking device. Oura has been presenting daily physical condition changes as scores and insights, focusing on sleep, condition, activity, stress, heart rate, and women's health. It is evaluated as a device that visualizes daily body changes afterward, rather than a device that operates something on a screen like a smartwatch.

With the Oura Ring 5, it aims to realize its role in a more natural form. The previous Oura Ring, when viewed as a ring, was somewhat thick and gave the impression of a gadget with sensors. When making a fist, some felt the thickness between adjacent fingers. While some people were not bothered by this, there were likely situations where they felt "it's still different from a regular ring" during sleep or daily activities.

The Oura Ring 5 is trying to directly address this discomfort. Enhancing the naturalness as a ring is the biggest update this time.

"Wearing Continuously" Becomes More Important Than "Adding Features"

In the wearable market, the competition has long been based on the number of sensors and the variety of measurement items. Heart rate, blood oxygen, skin temperature, sleep stages, stress, activity level, respiratory rate. Each new model drew attention for "what can now be measured."

However, the evaluation axis for the Oura Ring 5 is slightly different. Having already reached a stage where many health metrics can be measured, the important thing now is "how naturally can that data be continuously collected."

Health data has little meaning if measured for just one day. Trends in sleep, accumulation of fatigue, recovery after exercise, response to stress, changes in body surface temperature become visible only when recorded over the long term. Therefore, what is necessary for wearable devices is not just the convenience of moments when the user consciously uses them. Rather, the most important thing is that they can be worn continuously without being conscious of them.

In that sense, the miniaturization of the Oura Ring 5 is not just a design change. It is an update that improves the very foundation for continuously collecting health data. As the ring becomes thinner, lighter, and closer to jewelry, users can forget they are wearing it. The more they forget they are wearing it, the less likely the data is to be interrupted. The less likely the data is interrupted, the more meaningful the app's analysis becomes.

What the Oura Ring 5 indicates is that the evolution of wearables is beginning to shift from "multifunctionality" to "invisibility."

Positive Reactions on Social Media: "Looks Like Jewelry"

Looking at reactions on social media, the design change of the Oura Ring 5 is generally received positively. Especially in the Oura user community on Reddit, comments such as "It's small and looks like jewelry from any angle" and "Looks like ordinary gold jewelry" can be seen.

Regarding the old model, there was an impression of a "thick ring," for better or worse. Some posts described previous models before the Oura Ring 4 as "like a golden tire," and in contrast, the Oura Ring 5 is evaluated with comments like "finally looks like a real ring" and "closer to an actual accessory rather than a thick band for data collection."

This reaction indicates that the direction of the Oura Ring 5 aligns with market needs. Many users choosing smart rings are those who want to avoid screen-equipped devices like the Apple Watch or Galaxy Watch. They prefer to quietly record sleep and recovery rather than check notifications during exercise. They find it uncomfortable to sleep with a smartwatch on. They feel smartwatches don't match their fashion sense. For such people, the Oura Ring 5, which has become closer to a regular ring, appears attractive.

Additionally, a feature of smart rings is that they do not strongly advertise "health management" to those around them. Smartwatches are recognizable by their appearance, but with a design close to jewelry like the Oura Ring 5, it hardly makes one aware that it is a health tracker. This is a significant strength in attracting those who have been resistant to wearable devices.

On the Other Hand, Some Discontent with Being "Too Ordinary"

However, not all users welcome the slimming down. On social media, there are voices saying, "It's become too much like ordinary jewelry" and "The Oura uniqueness has faded."

This is an interesting reaction. The previous Oura Ring, with its thickness and presence, had become a kind of brand icon. People around would ask, "Is that an Oura?" giving users a sense of ownership and recognition as a gadget. With the Oura Ring 5 becoming closer to a regular ring, some feel that its "recognizable presence to those who know" has weakened.

In other words, the design evolution of the Oura Ring 5, while enhancing comfort, can be said to sacrifice brand visibility. For many, this is a welcome change, but for users who were attached to the thick ring, it may seem lacking.

This is also evidence that the smart ring category is maturing. In the early stages, the mere act of "wearing something new" tends to be valued. However, as it enters the diffusion stage, blending naturally into life becomes more important than standing out. The Oura Ring 5 is clearly a product that has chosen the latter.

Should Existing Users Upgrade?

The most challenging decision is for existing users of the Oura Ring 4 or Gen 3. On social media, there are opinions that "the Oura Ring 5 is mainly an upgrade in appearance and comfort, and not essential for current users."

This is a quite realistic view. Oura often extends software features to existing models, meaning not all new features are exclusive to the latest hardware. Therefore, the reason to buy the Oura Ring 5 is not because the information seen in the app changes dramatically, but because the wearing comfort is greatly improved.

If you are already satisfied with the Oura Ring 4 and have no complaints about thickness or wearing comfort, there may be no need to rush to upgrade. On the other hand, for those who feel discomfort during sleep, are bothered by the thickness between fingers, or want it to look more like a regular ring, the Oura Ring 5 is a very attractive upgrade.

Especially for users of Gen 3 or earlier, the accumulated improvements in design, battery, sensor structure, and app experience are likely to result in high satisfaction with the upgrade. On social media, there are also voices saying, "The size difference alone is worth the upgrade" when switching from the old model.

Discontent with Price and Subscription

On the other hand, a noticeable dissatisfaction with the Oura Ring 5 is its price. In Japan, even the cheaper models start at 65,800 yen, and depending on the finish, it can go up to 81,800 yen. Furthermore, to fully utilize the Oura experience, a membership fee is required.

According to Oura's official support, in the U.S., the Oura Membership is offered at $5.99 per month or $69.99 per year. Prices vary by region, but the fact that continuous billing occurs even after purchasing the hardware is a concern for some users.

On Reddit, there are comments with the sentiment that "the subscription fee cannot be justified in addition to the price of the ring itself." Since Oura's value heavily depends on the app's analysis and insights, removing the subscription diminishes its appeal. In other words, the Oura Ring 5 is not just a one-time purchase ring but also an entry point to a health data service.

This business model supports continuous feature improvements and advanced data analysis, but it also poses a psychological hurdle for users. Especially in the smart ring market, there are competitors that emphasize no need for a subscription. For Oura to continue expanding its support, it needs to continuously demonstrate value that matches the monthly fee.

Not All-Purpose as an Exercise Tracker

The Oura Ring 5 is strong in health management, but caution is needed if considering it as a replacement for a sports watch that records detailed data during intense exercise.

On social media, there are cautious opinions about data accuracy during high heart rates. While Oura supports activity recording for running, cycling, and strength training, some users suggest that "heart rate data during high-intensity exercise should be supplemented with another device."

This is a challenge common to smart rings. While fingers are considered easy locations to obtain biometric information, during exercise, factors such as gripping, sweating, changes in blood flow, and ring slippage can occur. While strong in capturing trends during sleep or rest, for serious training management, chest heart rate belts or sports watches may be more suitable in some situations.

Therefore, it is better to think of the Oura Ring 5 as a device for understanding sleep, recovery, and daily physical condition changes, rather than a device that accurately records all aspects of exercise. It is a tool for knowing whether the body is recovering today, the quality of sleep, and whether stress is not increasing, rather than managing detailed performance in strength training or running.

Attention to Size Selection

On social media, voices regarding size selection are also prominent. Since the Oura Ring is ring-shaped, if the size does not fit, both comfort and measurement accuracy are compromised. Especially since the Oura Ring 5 is thinner than before, the wearing comfort may change even with the same size notation.

Some posts mention that they thought it fit with the size kit but felt it was loose with the actual product. Conversely, there are voices saying that the actual metal product feels more comfortable than the plastic sizer.

Unlike smartwatches, smart rings cannot be finely adjusted with a band. Finger swelling can also change in the morning and evening, with temperature, after exercise, or after drinking alcohol. Before purchasing, it is important to use a size kit and check by wearing it for at least one night. For products like the Oura Ring 5, which are meant to be worn constantly, size selection greatly affects satisfaction.

The Future of Wearables Indicated by the Oura Ring 5

The introduction of the Oura Ring 5 holds significant meaning for the smart ring market. It is not just a new product from Oura but also a symbolic model indicating where wearable devices are headed.

Wearables have evolved as "computers worn on the body." They have screens, notifications, apps, and users operate them. However, the Oura Ring 5 aims for the opposite. It has no screen, does not assert itself, eliminates the feeling of being worn, and quietly collects data.

In the future, health management devices will increasingly blend into everyday life. Rings, earphones, clothing, glasses, bedding. Sensors will move from conspicuous gadgets into everyday items. At that time, what will be important is not only "what can be done" but also "how naturally it can be used continuously."

The Oura Ring 5 clearly indicates this direction. The closer smart rings get to regular rings, the more recording health data becomes a non-special act. Reducing the burden of worrying about charging before bed, wearing it for every exercise, and being interrupted by notifications. Just by wearing it, you can see changes in your body.

Of course, challenges remain. The price is high. There are complaints about the membership. The accuracy during exercise may not match that of sports-specific devices. For existing users, the reason for upgrading is skewed towards comfort.

Nevertheless, the value of the Oura Ring 5 is clear. It has brought the smart ring closer to "everyday jewelry" from a "health management gadget." This is the biggest evolution this time.

Conclusion: Who Should Buy and Who Should Wait

Those who should buy the Oura Ring 5 are people who want to continuously monitor sleep, recovery, and daily physical condition changes. It is suitable for those who are uncomfortable wearing a smartwatch during sleep, tired of screen-equipped devices, and want to manage health without compromising on fashion.

Also, for those using Oura Ring 3 or earlier with dissatisfaction in wearing comfort, battery, or appearance, the satisfaction with upgrading will likely be high. Especially for those who felt "the old model was too thick," the slimming of the Oura Ring 5 is a major attraction.

On the other hand, those satisfied with the Oura Ring 4, those who prioritize exercise recording, and those resistant to subscriptions should think carefully. The Oura Ring 5 is not an all-purpose health device but a smart ring strong in understanding sleep, recovery, and health trends.

The Oura Ring 5 may not be a dramatic revolution when looking only at the specs. However, in wearables used daily, "not being noticeable" is of great value. A small ring worn on the finger transforms health management from a conscious task to a part of life. The Oura Ring 5 can be said to be
