Recently, a friend complained to me about how uncomfortable headphones are to wear. They said that after just a short while of listening, their ears would start to hurt, making it unbearable to continue. They questioned the usefulness of such headphones, as no matter how good the sound quality, it's impossible to enjoy if it's causing discomfort. After hearing this, I asked him what kind of headphones he was using. He replied that they were regular Bluetooth earbuds, and when I inquired if they were in-ear, meaning they were inserted into the ear canal, he confirmed that they were. This made sense, as in-ear earbuds can to some extent solve the problem of sound leakage, reduce sound loss, and even provide a physical noise-isolating effect, making it easier to achieve good sound quality.

However, with the advancement of technology, headphones nowadays have significantly improved in sound performance, and it's no longer necessary to use in-ear designs to match the sound quality of in-ear earbuds. Therefore, I recommended to my friend the latest NanKa OE CC2 model. Without further ado, let's experience it together.

Design

The NanKa OE CC2 features a hanging ear design, which means the charging case for the headphones is larger than that of typical Bluetooth earbuds. The advantage of this is that it can accommodate a larger battery capacity, and the speaker unit can also be made larger. As a result, it has inherent advantages in terms of battery life and sound quality that small earbuds cannot match.

My friend chose the sky blue color for the headphones, which is quite attractive. After all, headphones nowadays are not just for listening to music; they also serve as a fashion accessory that can showcase one's personality and pursuit.The headphone design incorporates ergonomic principles, featuring a brand-new ear-hook design that is tailored to the ear characteristics of the local population, creating a curve that best fits the general public, to maximize the fit with our ear contours. Coupled with the lightweight design of the headphones, the weight of a single earpiece is further reduced to just 8.7 grams. Wearing them is comfortable, as if you're not wearing anything at all, without any sense of burden.

Moreover, the black ear-hook part is made of skin-friendly silicone material, which also has antibacterial effects. It feels soft to the touch, completely devoid of the rigidness of plastic, and is made from high-quality materials, so you don't have to worry about hygiene issues related to bacteria growth from sweat during prolonged use.

For even greater comfort, NanKa has meticulously crafted a 31-degree suspended inclined wearing method. By re-optimizing the center of gravity of the headphones and achieving a reasonable weight distribution, the design ensures a balanced center of gravity around the ear, avoiding awkwardness like being too heavy in the front and light in the back, making the wearing experience more comfortable and stable.

Additionally, their proprietary headphone suspension comfort technology has been upgraded to EAA 2.0. This is a technology specifically designed for open-ear headphones, allowing friends who wear glasses to enjoy this headphone experience perfectly. There's no need to worry about compatibility issues between headphones and glasses. Even if you're running or exercising while wearing glasses, you can comfortably wear these headphones. Just think about how impressive that is.

ConfigurationAfter examining the exterior, let's delve into its configuration and performance. The Nank OE CC2 is equipped with its proprietary Super Sound OS acoustic system, a feature typically found only in Nank's flagship earphones. It achieves triple real-time listening optimization, further upgrades the algorithm, and can dynamically adjust specific frequencies of the sound spectrum, intelligently compensating for the lack of audio curves, making the performance of the three frequency bands more balanced and authentic.

At the heart of the hardware is its sound-emitting unit, which features Nank's self-developed Super Bass 3.0 high-performance sound unit. This is an extra-large titanium-plated diaphragm sound-emitting unit with a diameter of up to 18.1mm. Such a large size brings richer details and more spectacular dynamic performance, especially in the low-frequency range, which is an effect that smaller-sized sound-emitting units cannot replicate. This allows the small earphones to immerse us in a lifelike audio world.

In terms of software, the NANK Golden Ear tuning team has conducted in-depth calibration on these earphones. By enhancing dynamic bass, ear canal compensation, and personalized listening experiences through three major technologies, they fully leverage the advantages of the hardware, making the sound clearer, fuller, and richer in detail.

Additionally, as an open-ear design, we don't have to worry about sound leakage. Although it is not in-ear, it features the DS2.0 directional audio delivery technology, ensuring that the sound emitted by the earphones enters the ears more completely, without sound leakage and minimizing the loss of audio quality. When listening to music, it does not disturb others nor does it reveal one's privacy.

The earphones also come with the latest Bluetooth 5.4 and dual ENC call noise reduction. Utilizing a brand-new generation of directional dual-microphone arrays coupled with powerful call noise reduction algorithms, it filters out background noise during conversations, eliminating and suppressing environmental noise in real-time. Furthermore, with Nank's innovative acoustic enhancement technology, it strengthens the clarity of human speech, significantly improving call quality. Whether on a noisy street, an airplane, or a subway, the communication experience is akin to a face-to-face conversation.With the support of Bluetooth 5.4, wireless connections will be more stable and faster, and the latency will be further reduced to 0.06 seconds in gaming mode. This makes it a great choice for wearing these headphones for extended periods of gaming.

Usage Experience

Having said that, what is the actual experience like with the headphones? In terms of comfort, the Nank OE CC2 is indeed comfortable to wear. There is no plastic roughness when it rests on my ears, and after wearing them for over an hour, my ears still feel as comfortable as before. Compared to traditional in-ear headphones, it is truly much better.

Moreover, once worn, the fit is quite secure. Even if I vigorously shake my head, they do not fall off. This makes them very suitable for running without worrying about the headphones falling out. They can be confidently used for cycling, running, jumping, and other activities.

After turning on the headphones, the connection is swift. When I play my favorite songs and the familiar sounds come through, the feeling is immediately immersive. Its low-frequency performance exceeds my expectations, and the mid and high-frequency performance is as excellent as always. Overall, the three-frequency performance is balanced, and the sound has a good sense of layering and detail. As an open-ear headphone in the price range of over three hundred dollars, its sound quality is worth its price.

Additionally, its battery life is long enough. With a single full charge, I can listen to music for 8 hours continuously. Whether it's for a long-distance marathon run or climbing a peak to watch the sunrise, these headphones are more than capable. It's important to note that its charging case can provide two more full charges, extending the total battery life to 24 hours. This means that even on a long journey, you can listen to music whenever you want without the anxiety of running out of battery.Additionally, it boasts an IPX5 level of water resistance, so even if you are wearing the earphones outside and encounter rain or excessive sweating, it won't have much impact on the earphones. Therefore, it is not an exaggeration to say that it is a pair of professional sports earphones.

Summary

Overall, the Nank OE CC2 earphones offer good sound quality, comfortable wearing, and are aesthetically pleasing. Friends who have tried them also like them very much. For a value of over 300 yuan, having so many advantages is indeed a sincere work from Nank. If you also enjoy sports and like to listen to music for extended periods, these earphones are worth a try.
