I've been in the headphone space for many years and have a deep understanding of the various styles and functions of headphones. Open-back headphones are a new type of headphones that are designed to be worn without touching or hurting the ears, making the upper ear more stable and comfortable, and more suitable for sports use. Open-back headphones are becoming more and more popular among consumers due to their unique advantages in terms of comfort, sound quality, and performance. Recently, many people have asked for the choice of three open-back headphones, Nanka MIX, Oladance OWS 2 and Shokin OpenFit, and it is necessary to make a comprehensive comparison of these three headphones in order to make users who are interested in buying more quickly understand the performance of each headset. In this way, you can understand the details more rationally, avoid blindly following the trend, and ensure that you choose an open-back headphone that suits you. 
Let's take a look at the performance summary of these three headphones first:South Carolina OEMIXBasic parameters:Headset**: 499R Bluetooth chip: V54. Waterproof performance: IPX5 battery life: 8+17h
South Carolina recently launched open-back headphonesoe mix, which can be said to be the final work in 2023, has a different experience compared to bone conduction headphones, and is known as"The king of value for money"., in the hundred-dollar **, figureValue for money and qualityYou must be right to pick it. The biggest highlight of this headset is its ability to express sound quality, passsuper bass 3.0 high-performance sound unit + low frequency enhancement technologyIt also features a high-end Bluetooth SoC chip that supports the latest in open-back headphonesBluetooth 54protocol to ensure that the signal transmission is stable and reliable, whether it is a call or a gameAudio and video synchronizationto provide a smooth experience. 
South Carolina OE Mix is equipped with:Dual-microphone ENC call noise cancellation, double microphone and double channelAI algorithmsto get the two microphones working closely together. If you are talking in a noisy environment, the ambient noise around you will be affectedIntelligent identification and elimination。Eliminates multi-band ambient noise during calls, so you can make calls clear even in noisy environments. MonauralWeighs only 67g, light and comfortable to wear, original".EAA hover comfort technology"Design, you won't feel tired when wearing it for a long time. And there is also a single one8hWith ultra-long battery life and other configurations, it is basically the only one who can experience the most advanced acoustic technology of the big factory in this price segment. Shokin OpenFit open-back headphones,Basic parameters:Headset**: 1298R Bluetooth chip: V52. Waterproof performance: IPX4 battery life: 7+21h
The design of the earhook does not fit into the ear, adopts ergonomic design, and the weight of a single earphone is about 83g, earhook is 0The 7mm flexible titanium wire material can meet the wearing of different shapes of ears, the upper ear is more comfortable, and there is no obvious sense of oppression, but the stability of the earphone is not very good, and there will still be shaking during large-scale exercise. The low-frequency performance of the headphones is very good, equipped with a new 18mmx11mm dynamic driver unit, plus lightweight polymer materials and double-layer ultra-smooth carbon fiber, with OpenBass low-frequency enhancement algorithm, the bass performance is more surging, deep diving, full and transparent, but the high-frequency texture of the headphones is not good, and it sounds nothing special. The headphones also do a decent job of preventing sound leaks, with no significant sound leaks. 
The headset supports Bluetooth 52 chips, stable and fast connection, long distance, low power consumption, but the headset has a high latency, which is not friendly to users who often play games, and it is usually used to catch up on dramas and listen to ** It is still very good. In terms of calls, to be honest, the quality is not good, and it sounds slightly noisy and echoy, and the noise floor is serious. OpenFit brings 28h total battery life, which can be used for about 7h at a time, which actually doesn't sound so long, similar to South Carolina 00 pressure. It also supports IPX4 waterproofing, so it can be easily handled without impact on daily use. However, the headset does not support dual-device connectivity. Oladance OWS 2 Open Earphones:Basic parameters:Headset**: 1498R Bluetooth chip: V52. Waterproof performance: IPX4 battery life: 19+76H Bluetooth protocol: AAC SBC
Oladance as a whole is basically wrapped by silicone body and plastic shell, except for several pickup holes and air pressure holes, titanium memory wire plus skin-friendly silicone process, supplemented by multi-point support of geometric mechanics, a pull and a hang can be versatile for anyone's ears, will not hinder the existence of the glasses arm, but its stability is limited to the small movement of the head shake, and the larger activity may also be thrown out. 
Chose 16The 5mm speaker driver, with a bio-high-tech film and a powerful intelligent chip, coupled with the basis of the dynamic equalizer EQ algorithm, reserves part of the space in the front shell of the earphone to form a large sound cavity, and the sound quality is not bad. oladance ows is a dual-microphone directional voice system, friends who value the quality of the call should note that although it can maintain high-definition vocal recording, but for the environmental sound and wind noise cancellation effect is general, such as the subway station, the other party may not be able to hear clearly, to prevent the earphone from leaking, better protect privacy. In addition to it is using Bluetooth 52, so the performance of stability and low latency level is still very good, oladance ows a single battery life of up to 16 hours, and if you have a longer battery life, you can spend an additional 300+ to start the earphone charging case, and the overall battery life reaches an astonishing 95 hours. The following is a comparison of the headphones1. Upper ear comfortThe best wearing comfort varies from person to person, so it is best to try to wear Bluetooth headsets before buying to feel their comfort and stability, you can also refer to the weight, design size, material, pressure distribution, etc., the most important thing is the actual wearing feeling, and comprehensively feel the wearing of these three headphones. Weight comparison
Although the weight is directly borne on the ear, the material and ingenious structure will make the feeling of wearing completely different, like ear clip headphones, relatively speaking, the presence of large weight will be more obvious, but the weight has little impact on the ear headphones, just like Nanka OE MIX, the lightest weight earphones, directly reduce the burden of the ears from the source, but I feel the most comfortable to wear. Shokin also tries its best to reduce the weight in this regard, slightly heavier than OE MIX, but also much lighter than Oladance. Material comparison:
These three are made of silicone, but according to the comfortable feeling of wearing in person, they are ranked: Nanka "Shokin = oldance", the ear hook part and the sound unit are connected with hypoallergenic maternal and infant grade liquid silicone, Shokin is double-layer skin-friendly silicone on the ear hook, and the whole earhook of oladance is also soft skin-friendly silicone, and the advantage of Nanka is that there is a safety test to ensure the user's sensitivity to use. Pressure distribution:South Carolina OEMIXDuring the actual use, although there is no sense of presence on the wear, it is precisely because Nan** has tested the ear canal of 10w+ users that it is guaranteed to be stable and reliable when wearing. The 56:44 front and rear lightweight, stable center of gravity design, when using the treadmill in the gym, even if the activity is strenuous without the earphones dropping, there is no need to worry about stability. oladance ows 2:There is no official description of the design of this earphone, from the actual feeling, the pressure of the earphone and the whole falls on the upper ear cartilage, because the weight itself is not very light, so it is difficult to avoid the cartilage to bear a little more. Shokin openfit:The overall weight of Shokin is lighter than that of oladance, and the degree of weight dispersion is still good during wearing, but the weight on the back of the ear still feels soreness after a long time. 2. Sound quality performanceDiscussions about the sound quality of headphones are often inconclusive, and everyone's auditory standards for headphone sound quality are different. In the past, I used to judge the sound quality of my headphones based on my own criteria, but this time, in order to make the test more meaningful, I invited a lot of people to join me in the actual listening experience. We'll score the headphones on their mids, highs, and lows, as well as vocals and soundstage, to arrive at the best sounding headphones! 
South Carolina OEMIXOE MIX does a good job in this regard. It uses a large dynamic unit with a titanium polymer diaphragm, through Nanka's self-developed Super Bass 30High-performance sound unit + super sound os audiophile acoustic system is a combination of soft and hard, very sensitive, I used it in the process, I chose night running, cycling, subway cars, etc. as the audition environment, in the **maroon 5 songs, the surging and strong bass, the kind of rhythm brought by the rhythm, the environment with strong bass, the details of the ** performance are better, Cai Qin's "ferry" low frequency component is sufficient, whether it is the passion of pop, or the elegance of classical, can be perfectly presented by this headset, and the effect is not inferior to the thousand-yuan headset.
oladance ows 2:It uses its own virtual bass enhancement technology and dynamic EQ to make the sound field performance more open, and the bass effect is extremely stable. However, the naturalness of the vocals is a little more mediocre. As soon as the vocals appeared, I felt that the voice was a little muffled, and there was a sense of oppression. However, the performance of the instruments is quite passable, especially the presentation of the drum beats is quite good, and some powerful impact is felt. Overall, the "muffledness" of this sound is a bit of a mixed bag.
Shokin openfit:It's still good to listen to it with openfit headphones, I tried out the song "Because of Love", and I feel that the low-frequency instruments and singer's voice are still good! Especially the singer's voice, the native voice can still be heard, but the sense of transparency is still poor. The high-frequency performance will be somewhat lost, but it will be more rhythmic and energetic drum bursts, and the penetration and sound field restoration are in place.
3. Call noise reduction experiencePersonally, I really like to talk to friends while walking and chatting with friends while commuting from work, and in this case, the noise of the wind and the distraction of the people around me often have a huge impact on the call. In the actual call situation, although the ** is uncertain, but there are many interference factors, so the scene I selected for this test is a large supermarket, with both human noise and a lot of environmental noise, to see if the actual audition has any effect.
South Carolina OEMIXIts degree of sound leakage is very small, and its direct sound directional audio technology tracks the direction of sound transmission at all times, and its directional audio projection technology narrows the audio beam to less than 25°, so that the energy entering the ear canal is more concentrated. The Super Sound OS system automatically compensates for the audio curve through AI algorithms, improving the high-fidelity effect. Precise tuning allows sound to reach the ears of the listener, even in small confined spaces, without sound leakage, avoiding embarrassment and protecting privacy. oladance ows 2：Support dual-microphone directional voice system,Its sound leakage is not big at 50%The volume is not big,70% or so will be more obvious,This one pays more attention to the sound quality performance of the bass,So it may be that the noise improvement is still average。 Shokin openfit:Shokin uses DirectPitch technology, which essentially limits the direction of sound propagation and makes sound propagation more directed to the ear canal. After my actual measurement, this product can still distinguish a certain sound from a distance of tens of centimeters after the volume is adjusted to about 75% under the normal noise in the office. This technique may be helpful in reducing sound leakage, but there seems to be room for improvement in practice. Ending:After this test, I finally decided to stay with the South Carolina OE Mix. The headphones are exactly what I feel about in terms of sound quality and comfort. I hope that after reading this article, you will be able to find a headset that meets your needs. To summarize the characteristics of each model: if you pay attention to cost-effectiveness and comfort, Nanka OE Mix is definitely the first choice, ** and performance is simply an excellent match; If you pay more attention to appearance, Shokin OpenFit is also a good choice, with a slender body and a chic design; But personally, OlaDance OWS 2 is not to my taste. Hopefully, this summary will help you make the right headphone choice! Enjoy the New Year
