2. Some knowledge points of open-back headphones:
What are open-back headphones? What are the classifications?
Open-back headphones can be worn without entering the ear, making them more comfortable to wear and not tiring the ears for long periods of use. At present, open-back headphones are mainly divided into two types: air conduction and bone conduction, let's learn about them together;
Air conduction: Through the air transmission mode, beamforming technology is used for directional sound transmission, and the in-ear design accurately transmits the earphone audio to the nerves in the ear, and finally realizes the hearing. Unlike bone conduction headphones, there is no numbness when wearing the sound for a long time. Air conduction is closely related to our daily lives.
Bone conduction: It does not pass through the external auditory canal and eardrum, but transmits sound through the vibration of the skull and bones, and transmits it to the auditory nerve through the skull-bone labyrinth-inner ear lymphatic fluid transmission of the human head. For example, when we eat, we hear the sound of teeth squeaking, which is the sound of bone conduction.
3. What are the advantages and disadvantages of open-back headphones?
(1) Advantages:
More comfortable to wear: The design does not block the ears and does not hurt the ears, which improves the comfort of long-term wearing, and will not get tired after wearing it all day, without the strong discomfort and stuffiness caused by the long-term wearing of traditional in-ear headphones.
Safer sports: When exercising outdoors, you can enjoy music while maintaining awareness of the external environment, avoiding unnecessary things and greatly improving safety.
More healthy and hygienic: If it does not enter the ear, there will be no phenomenon of stuffy ear canal and unbreathable ear, on the contrary, the traditional Bluetooth headset will be stuffy and breathable for a long time, and if it is not cleaned regularly, it will also breed bacteria, resulting in symptoms such as ear infection and inflammation. Open-back headphones don't have to worry about these non-existent problems at all, and they are more enjoyable to wear without being in the ear.
Compatible with glasses: At present, more than half of the world's users wear glasses, and open-back headphones can be coordinated according to the fit of glasses, and wearing them will neither affect the wearing of glasses, nor will they fall, making them more stable and comfortable to wear, and better compatible with glasses.
(2) Disadvantages:
Sound quality performance: The sound quality of open-back headphones is generally poor, not as good as traditional in-ear headphones, because the working principle of open-back headphones is different, resulting in poor sound quality of headphones. However, for now, there are also a lot of open-back headphones that sound no worse than traditional in-ear headphones.
Sound leakage: It is inevitable that open-back earphones will leak sound, because in order to make it more comfortable for more users to wear headphones, open-back earphones will not fit the earphones tightly to the ears, so it will cause some sound to leak out. However, with the development of headphones, there are currently several brands that minimize sound leakage and better protect privacy, such as brands such as Nanka and Shokin.
Fourth, open-back headset purchase skills
Next, share some purchase tips, if you are not clear, you can refer to these points to make a choice!
I think it mainly depends on the following aspects;
1. Comfort
Comfort is the foundation of all experiences, and headphones are no exception, which is about the user's comfort and pleasure during long-term use, and the right design and ergonomics can reduce the pressure on the ears and head, allowing users to enjoy music for longer.
The design and material selection are directly related to the comfort of wearing, and soft, skin-friendly materials and design can reduce friction and discomfort on the ears and head, and factors such as even distribution of weight and adjustability are also important considerations for comfort.
2. Audio transmission protocol
The most used audio coding on the market is SBC, AAC, apt-X, LDAC four kinds, so the standard configuration of the headphones is SBC, which is also the oldest coding format, Apple commonly uses AAC, and so on, the higher the audio coding format, the more details are retained, and the better and more natural the listening experience. When we choose a Bluetooth headset, we first look at the highest encoding format supported by the mobile phone, and then choose the corresponding highest encoding format.
3. Bluetooth version
The Bluetooth version of the headset is also a point to note. Today's wireless headphones use Bluetooth chips for signal transmission, and the level of the Bluetooth version is directly related to the sound quality of the headphones. Therefore, the choice of Bluetooth chip becomes extremely critical. Most headphones on the market have adopted Bluetooth 5.1 and above, and some have upgraded to Bluetooth 5.3, and even the latest version 5.4, which means that their connectivity, anti-interference ability and transmission distance have been significantly improved. Therefore, choosing headphones with a higher Bluetooth version can better enjoy a stable, high-quality audio experience.
4. Delay
Latency refers to the time difference between an audio signal from the sender to the receiver, while low latency means that the sound and image are synchronized more accurately, which is important for users who need to watch videos or play games.
In terms of video viewing, if the latency is high, the missynchronization between audio and video may cause the character's mouth movements to be inconsistent with the voice, and for game users, high latency may cause the sound effect in the game to be out of sync with the actual picture, which will affect the smoothness of the game experience. Therefore, try to choose a relatively low latency when purchasing.
5. Endurance
For users who often use Bluetooth headsets, a longer battery life can reduce the number of charges, and avoid the embarrassing situation of interrupting the use due to insufficient power, for daily use, the headset body of more than 4 hours of single battery life and more than 20 hours of total battery life of the charging box is enough to meet the needs of most users, if it is a longer time of use or need to use Bluetooth headsets frequently, it is more practical to choose a headset with a higher battery life.
6, Sound leakage
Open-earphone sound leakage is unavoidable, but with the upgrading of headphones, many open-back headphones for sound leakage, through a certain technical upgrade, improvement, although not completely avoidable, but can also be reduced to the minimum, no obvious sound leakage. At present, the brands that have done a good job in sound leakage include Nanka, Oladance, cleer, etc.
The above content mainly introduces the parameters of some headphones, and I will use the simplest method to tell you how to choose the right headphones for you, in fact, the most important point is to depend on your own needs
It's important to know what you need before you buy headphones. Because different headset types and functions are suitable for different scenarios and user needs. Knowing what you need can help you choose the right type of headset
Need to wear for a long time – open-back headphones (lightweight and comfortable to wear)
Need to play games - low latency, high definition
Need to go out outdoors often or commute daily - open-back headphones (safe and secure)
Running, fitness, swimming - choose waterproof ones
5. Physical evaluation of popular styles of open-back headphones
Under the many open-back headphone brands, if you don't know how to choose open-back headphones, you can't go wrong with choosing a big brand, let's test the ten most popular open-back headphones on the market for different dimensional tests, I mainly test from these four aspects: comfort test, sound quality test, Bluetooth test and sound leakage test;
(1) Comfort test
Wearing comfort is undoubtedly a crucial factor when evaluating the headset wearing experience. In order to delve deeper into this, we need to take a nuanced look at headphones from multiple dimensions. First of all, the appearance design of the headphones is directly related to their comfort when wearing. Secondly, the weight of the headphones is also an important factor that affects their wearing comfort. Let's talk about the touch of the material. The choice of material for headphones also has a significant impact on wearing comfort. From a comprehensive comparison of different dimensions, we can better understand the comfort and adaptability of each headset in different usage scenarios.
Weight Comparison:
第一档:南卡OE MIX、、韶音openfit
第二档:飞利浦TAA6708、漫步者Comfo Fit II、倍思Eli、万魔S30
第三档：开石OpenRock Pro、南卡OE PRO、Cleer ARC II、Oladance OWS PRO
Material Wearing Comparison:
NANKA OE PRO: using medical-grade liquid silicone material, this material has a delicate and smooth touch, and will not feel uncomfortable even if you wear it for a long time. Its flexible earhook structure and 31° tilt design ensure a balanced weight distribution that can be easily adjusted to the right position.
Oladance OWS Pro: Made of skin-friendly silicone material, it has a delicate feel and provides good comfort. It is designed with the need for prolonged wear in mind, reducing the strain on the ears.
Nanka OE MIX: Made of soft maternal and baby-grade silicone material, it can be worn comfortably for 4 hours without feeling pressured.
The brands that perform poorly in terms of wearing comfort are the Wanmo S30, OpenRock Pro, and Baseus Eli. These headphones may not have been designed with the stress and discomfort of prolonged wear in mind, especially as the Cleer ARC II's self-rotating design can cause discomfort during long-term wear.

(2) Sound quality test
We pay attention to the sound stage performance and sound quality balance. Sound stage performance evaluates the sense of direction and depth of sound in the headphones when playing audio, while sound balance refers to the volume distribution of the headphones at different frequencies. We use soundfield test tracks to feel the soundstage performance of the headphones, as well as to evaluate the sound quality balance of the headphones by testing the bass, midrange, treble and other frequency bands in the track.
I also auditioned with classic audition tracks such as "Ferry" (low frequency), "Possibility" (medium frequency), "Going Home" (high frequency), etc., and let my friends listen with me to feel which headphones have better sound quality. (20 points each, 100 points overall)
The results were:
90~100分：南卡OE PRO、Oladance OWS Pro
80~90分：南卡OE MIX、飞利浦TAA6708、韶音OpenFit、Cleer ARC II
70分及以下：万魔S30、开石OpenRock Pro 、漫步者Comfo Fit II、倍思Eli
According to the scoring results, the South Carolina OE PRO and Oladance OWS Pro received high scores in low frequency, mid frequency, high frequency, vocal and sound field performance, showing excellent sound quality in all aspects.
The sound quality of NANKA OE PRO is very distinctive:
In terms of low frequency, the drum beat of the prelude of "Ferry" dives vigorously and will not be stuffy, and you can even feel the vibration of the drum surface, with a strong sense of presence;
In terms of mid-frequency, the singer Cheng Xiang's voice is restored in place, which can perfectly show the characteristics and details of her voice, the elongation of the treble is very extensive, and the sense of substitution is super strong;
In terms of high frequencies, the saxophone is a little lacking in penetration, but it is much stronger than the headphones that also only have a dynamic unit;
The Oladance OWS Pro's low-end and mid-range feel is also very good: the mid-range instruments and vocals are richer, especially the singer's voice is sweet and ethereal; It has a full sense of transparency. NANKA OE MIX also performed very well in these songs, the vocals performed well, without losing too much sound energy, and the penetration and sound field restoration were relatively in place, and it was only a few hundred prices to hear.
Philips TAA6708, OpenRock Pro, and Cleer ARC II have also achieved good evaluations in terms of three frequencies, and the sound quality performance is relatively balanced, but some of them are not particularly good in terms of dynamics. On the other hand, the S30, OpenRock Pro, Comfo Fit II, and Baseus Eli may have some deficiencies in terms of clarity, resulting in a slightly lower overall score.
(3) Bluetooth test
In the headset connection and call test, the connection stability, latency performance and call quality of the headset are evaluated.
Each headset was thoroughly evaluated for its performance when connected to a device, covering a number of aspects such as Bluetooth connection stability, pairing speed, and signal coverage. In addition, the headset was specifically tested for latency in a variety of environments, especially when watching videos, gaming, or live calls, to ensure a smooth experience.
声音延迟性最低：南卡OE PRO、Cleer ARC II、南卡OE MIX
The new headset of NANKA OE MIX uses the latest 5.4 Bluetooth chip, which has higher data transmission speed, lower energy consumption, lower communication delay, further performance upgrades, adapts to more environments, and is still easy to use in complex scenes, super smooth without jamming, compatible with Android/iOS, and the compatibility is also stronger.
Nanka OE PRO uses Bluetooth Qualcomm 3040+5.2 chip, and also supports apt-x/apt-x HD and other audio quality, which can also have a higher definition sound quality experience when bringing lower power consumption, faster speed, and more stable signal connection.
The game version of Cleer ARC II is equipped with a 5.3 Qualcomm chip, and it is also very fast in connection, which may be related to the fact that this is the game version, I don't know if the experience of the other two versions will be different;
声音延迟性较低：Oladance OWS Pro、漫步者Comfo Fit II、倍思Eli、万魔S30
声音延迟性较高:飞利浦TAA6708、韶音OpenFit、开石OpenRock Pro
(4) Sound leakage test
Noise control is also an important evaluation metric. A good headset should be able to filter out outside noise, allowing users to enjoy high-quality music in a quiet environment. We will test the performance of the earbuds in different noise environments to evaluate their noise control capabilities.
When performing a sound leakage test, turn up the volume of the headphones to the maximum and use a noise decibel meter to measure the strength of the audio signal leaking from the headphones. This gives you an objective sound leakage index that can be used to assess the degree of sound leakage from the headphones. It is more intuitive to show the sound leakage performance of the headphones at maximum volume. By analyzing the test chart, you can understand the sound leakage of the headphones at various frequencies and have a more comprehensive understanding of their overall performance.
