Let me tell you about the popular science knowledge points of open earphones
1. What are the types of open-back headphones?
Open-back headphones can be divided into two categories: air conduction and bone conduction according to the different sound conduction mechanisms.
Air conduction headphones: Rely on air as a medium to transmit sound. This conduction mimics the process by which we naturally hear sound: sound waves travel through the air and through the external ear canal to the eardrum, causing the eardrum to vibrate. This vibration is then transmitted through the ossicles of the middle ear to the inner ear, where the auditory nerve sends the signal to the brain for interpretation. As a result, air-conduction headphones are able to provide an audio experience that is close to natural listening, making them suitable for a wide range of listening occasions and music enjoyment.
Bone conduction headphones: A completely different sound conduction mechanism is used. It transmits sound through vibrations, bypassing the outer and middle ears and directly through the skull to the inner ear. This type of conduction is especially suitable for use in situations where it is necessary to stay alert to the surrounding environment, such as outdoor sports, where the user can hear the music and the surrounding environment at the same time, ensuring safety. The design of bone conduction headphones gives them a unique advantage in specific application scenarios, especially when it is necessary to open both ears to perceive the surrounding environment.
2. What is the difference between open-back headphones and other commonly used types of Bluetooth headsets?

3. Open-back headset purchase list
The tips for purchasing are as follows:
I. Wearing comfort
In terms of wearing comfort, it mainly depends on the following points:
(1) Appearance structure design: The overall design structure of the earphone is one of the important factors that determine the wearing comfort. The ergonomic structural design not only effectively distributes the weight of the earbuds, but also fits perfectly to different pinna shapes to ensure stability and comfort during wearing. (2) Body material selection: Common earphone materials on the market include metal, plastic, and silicone, each of which has its own unique characteristics. Among them, the soft and breathable silicone material can significantly reduce the discomfort of wearing and provide a more comfortable wearing experience. According to personal preferences and needs, choose the right material to make it more comfortable to wear.
(3) Consideration of the weight of the earphone: The weight of the earphone is also a factor that cannot be ignored to affect the comfort. The lightweight headphone design reduces the pressure of wearing it for long periods of time, making it easier for users to enjoy their music.
II. Sound quality and listening
In terms of sound quality, the main thing to look at is the following:
(1) Audio decoding: In the field of wireless headphones, audio codec technology plays a pivotal role. Make sure your headphones and playback device are in the right encoding format for the best sound quality. Mainstream codec formats such as SBC, AAC, APTX, LDAC, LHDC, have their own advantages in terms of sound quality and delicacy, transmission rate, and delay control. Choosing a format that matches your personal listening preferences will significantly improve your overall listening enjoyment.
(2) Driver unit: As the core element that affects the sound quality, the quality of the driver unit is very important. The high-quality drivers deliver a clear, detailed and richly layered sound. Common types of drivers are armature drivers and armature drivers, each with its own unique sound characteristics. Larger drivers often mean a wider, more three-dimensional soundstage.
(3) Sound field performance: Excellent sound field design can create a wide and realistic sound space, so that the listener feels as if he is in the music and feels the layering and space of the sound. This immersive listening experience will bring you more colorful music enjoyment.
III. Bluetooth Connection
The version of Bluetooth technology, the speed of data transfer, and the level of latency can all have a significant impact on the connection stability and sound quality of the headphones. Connection distance and device compatibility are also important aspects to consider when choosing headphones. Compared with versions below 5.1, Bluetooth 5.4 provides stronger connectivity and lower energy consumption, bringing a smoother user experience.
IV. Latency Performance
Latency plays an important role in headset performance, especially for gaming enthusiasts. Noticeable audio delays can cause the sound to be out of sync with the picture, which can hurt the overall experience. Therefore, low latency is critical when choosing a headset to ensure smooth synchronization of audio and video content, especially in scenarios that require precise synchronization, such as gaming and watching videos. While it's impossible to completely eliminate latency, some high-quality open-back headphones on the market have been able to achieve virtually imperceptible low latency, providing a smoother listening experience.
V. Call Quality
When using a headset for a call, the quality of the call is crucial. Choosing a headset equipped with a noise-cancelling microphone can effectively reduce background noise, which can significantly improve the clarity of calls. In addition, some headsets feature ambient noise suppression, which provides a clearer call experience in noisy environments.
Fourth, ten popular open Bluetooth headsets measured and compared

I. Wear test
Wearing comfort of headphones is critical to the user experience, especially open-back headphones, whose unique design makes comfort evaluation particularly important. High-grade silicone materials, such as medical-grade flexible silicone and skin-friendly silicone, can bring an excellent wearing experience and reduce the discomfort of long-term wear. In order to make an accurate evaluation, I will wear each earphone for at least 2 hours, focusing on the material, appearance and actual wearing feeling, so as to provide you with a valuable reference.
After actual testing, the five headphones of Nanka OE MIX, Shokin OpenFit, Comfo Fit II, Shengkuo AeroFit and Nanka OE PRO have performed well in terms of comfort. Among them, the South Carolina OE MIX brings a wearing experience as if nothing is due to its extremely light single weight of only about 6.7 grams. Combined with EAA Hovering Comfort Technology, it can precisely adapt to different ear canals, ensuring a maximum fit of up to 99.9%, which not only enhances stability, but also provides the ultimate comfort, especially considering the needs of users who wear glasses.
Shokin OpenFit, Comfo Fit II and AeroFit pay the same attention to lightweight design, bringing a lightweight wearing feeling, even after long-term use, it is difficult to feel the pressure. However, it is important to note that these headphones may still be at risk of coming loose and falling off during strenuous exercise. SOUTH KA OE PRO provides a comfortable wearing experience through its innovative 31° tilt angle design, which perfectly fits the structure behind the human ear and combines with medical-grade liquid silicone material.
In contrast, the three headphones of Wanmo S30, Baseus Eli and Oladance OWS Pro perform reasonably in terms of wearing comfort, without bringing a significant squeezing feeling. As for the OpenRock Pro and Cleer ARC II headphones, although they perform well in terms of stability, due to their large volume and uneven weight distribution, they may bring a certain sense of pressure when worn, affecting the overall comfort, and it is recommended to improve.
II. Sound quality test
In order to accurately evaluate the sound quality of each headset, we have carried out a series of comprehensive and detailed sound quality evaluations. In this review, we paid special attention to the depth and fullness of the low frequencies, the clarity and balance of the midrange, the delicacy and transparency of the high frequencies, and the authenticity and emotional communication of the vocals, as well as the depth of the sound field width. In order to ensure the accuracy and objectivity of the evaluation results, we carefully selected works covering a variety of music styles such as classical, pop, rock, etc., and conducted a comprehensive test. A number of colleagues were also invited to participate in the audition session and rate them according to their own listening experience, in order to obtain more comprehensive and rich evaluation feedback.
After actual testing, the performance of the four models of Nanka OE PRO, Oladance OWS Pro, Shokin OpenFit, and Nanka OE MIX is still very good and colorful. In particular, Nanka OE PRO, with its brand after 13 years of acoustic technology precipitation, is equipped with Super Bass 2.0 high-performance sound driver, which integrates 16.5mm large dynamic coil and ultra-thin light diaphragm technology to create a wide range of sound and shocking bass performance. The blessing of the OS high-end acoustic system, combined with the well-tuned acoustic cavity design, ensures the accurate restoration and balance of sound. The low end is deep and powerful, the midrange is mellow and natural, and the high end is clear and bright, and the overall sound quality is balanced and richly layered.
Oladance OWS Pro and Shokin OpenFit both tend to be biased towards the low and middle frequency parts, with the vocals in the ear, the sound field is open and natural, and the layers are clear, but the high-frequency analysis is not high, and the texture is relatively flat. Although the NANKA OE MIX is positioned more affordable, its acoustic performance is not inferior to that of higher-priced competitors. Cleer ARC II, Comfo Fit II, and AeroFit are more inclined to the mid and high frequencies, with a full texture and distinct layers, and the coordination with the instrument is relatively harmonious, but the low frequency is slightly weak, and the strength and impact are not enough.
Baseus Eli, OpenRock Pro and Wanmo S30The overall sound quality is relatively mediocre, although they can meet the basic listening needs, but they lack style adaptability and purity, sometimes accompanied by slight noise interference, it is difficult to meet the expectations of users with high requirements for sound quality.
III. Connection Testing
The Bluetooth connectivity test is designed to comprehensively verify the connection stability and distance of the earbuds to ensure that users can have an excellent experience in a variety of environments. Here are the tests for three typical scenarios:
Scenario 1: Subway station
In subway stations, wireless devices are dense and signal interference is frequent, which poses a severe challenge to the connection stability of Bluetooth headsets.
Scene 2: The sidewalk of the road
When outdoors, users may place their phones in their bags or pockets, so the connection distance becomes an important indicator to measure the performance of Bluetooth headsets. On the sidewalk of the road, there may be some distance and obstacles between the headset and the mobile phone.
Scene 3: Indoor scene
To verify the headset's ability to transmit sound in scenarios that require instant feedback, we tested indoors for entertainment activities such as gaming and streaming.
After actual testing, Nanka OE MIX has the best performance in terms of connection stability, equipped with the latest Bluetooth 5.4 version, providing a connection distance of about 18cm and fast transmission speed, achieving fast connection and response. The Bluetooth 5.4 chip SOC specially customized for the open-back headset ensures a stable connection without jamming. It is followed by the Oladance OWS Pro, Cleer ARC II, AeroFit, Edifier Comfo Fit II, and South Carolina OE PRO, which also do a good job in connection stability, with a connection distance of about 15cm and smooth audio playback.
In terms of latency, the SAN OE MIX, SAN E PRO, and Cleer ARC II perform the best, especially for gaming, maintaining real-time footage and low latency without stuttering. Thanks to its patented low-latency technology, Nanka's two earphones effectively reduce external electromagnetic interference by optimizing the signal transmission path, ensuring the efficient propagation of audio signals and achieving audio and picture synchronization.
On the other hand, the Comfo Fit II, AeroFit, and Baseus Eli perform reasonably well in terms of latency, with no noticeable lag. Comparatively speaking, OpenRock Pro, Shokin OpenFit, Oladance OWS Pro and Wanmo S30 have obvious latency problems, and the sound and picture are often out of sync, which affects the user experience.
IV. Call Test
As a key indicator to measure the performance of Bluetooth headsets, call quality involves multiple dimensions such as clarity, noise suppression, and audio synchronization. To better understand the call performance of different headsets in various environments, we used a series of tests:
First, in a quiet indoor environment, such as a home or office, we conducted a preliminary call test. Both parties use open-back headsets and have conversations in the same space. At the same time, we keep an eye out for echoes, whistling or other interfering sounds to ensure that the call quality is fully examined.
We then expanded the test scenario to outdoor environments, including busy streets, subway stations, and noisy places such as shopping malls. Make mobile calls in these environments to simulate real-life everyday life scenarios. Focus on evaluating the clarity and audibility of the headset in noisy environments, and record the impact of ambient noise on call quality in detail.
Finally, we have also set up a simulated noise environment test, including simulated vehicle noise, wind noise and other extreme conditions. In this environment, we test the noise cancellation and call clarity of the headset to fully evaluate its performance under extreme noise conditions.
After actual testing, the four headphones of Nanka OE PRO, Nanka OE MIX, Shengkuo AeroFit and Oladance OWS Pro stand out with their advanced call technology and strong anti-interference ability. Whether it is a quiet indoor environment or a noisy outdoor scene, it can rely on its 4 headwind array noise-canceling microphones and efficient ENC noise-canceling technology to accurately block all kinds of background noise in real time and ensure that the two sides of the call communicate clearly as if they were in the same space, without any sense of distance.
At the same time, the three products of OpenRock Pro, Shokin OpenFit and Comfo Fit II also show better call quality, although they do not reach the level of the first four, they can still provide a stable and relatively clear call experience in daily use, meeting the basic needs of most users.
However, the performance of the S30, Baseus Eli and Cleer ARC II headphones is slightly inferior in terms of call performance. During the call, it often encounters obvious environmental noise interference, and sometimes even causes the other party's voice to be blurred or completely unrecognizable, which seriously affects the normal voice communication.
