With the development of the mobile Internet, Bluetooth headsets have become an indispensable mobile device in public life. In the category of bluetooth earphones, open bluetooth earphones have attracted much attention due to their superior comfort, safety, and portability. Compared with traditional Bluetooth headsets, open-back headphones only need a small main body to be hung directly on the ears, without any pressure on the ears. They have excellent ventilation and comfort, and are very suitable for long-term wearing and ear wear. Sensitive user usage.
However, early open Bluetooth headsets also had pain points such as insufficient sound quality and sound leakage, and did not develop well. In the past two years, outstanding brands in the industry have greatly improved the sound quality performance of open Bluetooth headsets through careful tuning. Some products have become comparable to traditional Bluetooth headsets in terms of sound quality details. At the same time, the sound leakage and connection of open headphones have also been improved. Greatly enhanced, it can be used as a mature consumer electronic product.
There are dozens of open-type Bluetooth headsets that I use, and I have a deep understanding of open-type headsets. This article will comprehensively compare the popular open Bluetooth headsets on the market from the dimensions of sound quality, battery life, connectivity, comfort, etc., and provide recommendations for open Bluetooth headsets in different price ranges, as well as relevant science content about open headphones. The full text is 10,000+ words, and it took more than 5 weeks for actual testing! Hope to recommend the most suitable open bluetooth headset for the majority of users!
At the beginning, let me talk to you about a widely concerned issue.
Are open-back headphones an IQ tax?
Since open-back headphones appeared on the public scene, I have heard a lot of voices similar to "open-back headphones are an IQ tax", but personally I don't think they are an "IQ tax". In fact, they have many benefits. For example, the following points.
More comfortable to wear: Open-back headphones adopt a non-blocking and non-ear-damaging design, which greatly improves the wearing comfort. You will not feel tired when worn all day long, and will not cause strong discomfort and ear stuffiness like traditional in-ear headphones when worn for a long time. . It can also significantly reduce ear fatigue. Traditional in-ear headphones are easy to cause strong discomfort when worn for a long time, but open headphones do not. Even if you listen to music for two or three hours, your ears will not feel swelling, pain or fatigue.
More suitable for sports: The open design is not only more stable to wear, but also allows you to hear the sounds of the surrounding environment without completely blocking external sounds. Therefore, it is especially suitable for outdoor sports, cycling, driving and other occasions where vigilance is required.
Health and hygiene: Frequent wearing of traditional headphones can easily lead to ear canal infections, especially for users with sensitive ears. If they are not cleaned for a long time, bacteria can easily accumulate in the ears, causing ear infection and inflammation. Open-type headphones are not inserted into the ears, and even if used for a long time, they will not accumulate bacteria and cause infection, making them more hygienic and healthier.
Comfortable ear pressure: Due to the open design of this type of earphones, air can be allowed to circulate into the ears when worn, so there will be no "ear pressure" problem with closed earphones, which is also helpful for ear health.
Here are some recommended styles first. Those who are not interested in popular science content can choose to buy them first. They are all better styles after actual testing.

1. What are open-back headphones?
The biggest difference between open-back headphones and ordinary headphones is that they don’t need to be plugged into the ears, they are comfortable to wear and not easy to fatigue after long-term use. Open-back headphones are mainly divided into two types: air conduction and bone conduction.
Air conduction headphones use beamforming technology for directional sound transmission, which can accurately transmit sound to the ears without entering the ears, achieving a listening effect. Unlike bone conduction headphones, air conduction headphones are more comfortable and comfortable to wear for long periods of time. Air conduction uses air to transmit sound, which is closer to people's daily life experience.
Bone conduction headphones use the skull to conduct sound vibrations, without passing through the external auditory canal and eardrum. They pass through the skull, bony labyrinth and then to the inner ear lymph, and finally the sound signal reaches the auditory nerve. For example, the sound made by our teeth when we chew is a typical bone conduction effect.
2. Who is suitable for open-back headphones?
People who need to wear headphones for a long time: Due to their open structure, open-type headphones can keep the ears ventilated and reduce the moisture and pressure caused by long-term wearing. The comfort is much higher than ordinary Bluetooth headphones, making them very suitable for people who need to wear headphones for a long time. Crowd, can protect ears well. For example, open-back headphones are a better choice for senior music and film lovers, students, business personnel, customer service and other people who need to wear headphones for a long time.
People with more sensitive ears: Open-back headphones are also particularly suitable for people with ear-related diseases, such as otitis media, ear canal infections, ear injuries, etc. Because open-back headphones are not inserted into the ear canal, they will not affect the ear canal, nor will they cause or aggravate symptoms. For people whose ear canals are small and sensitive and are not suitable for wearing ordinary headphones, open-back headphones can also be worn easily.
Sports enthusiasts: In addition, open-back headphones are ideal for sports groups. When wearing it, sweat will not flow into the ear canal with the earphones, ensuring that the ears are clean. Open-back headphones are comfortable to wear and cause no discomfort. Most open-back headphones have good stability, are not easy to fall off during exercise, and are easy to use.
3. How to choose open-back headphones?
It is actually not difficult to choose open-back headphones. Generally speaking, you can choose the one that suits you by mainly referring to the following factors.
Sound quality experience:
Let’s talk about sound quality first. This is also one of the most important factors affecting the experience of using Bluetooth headsets. Nowadays, many people can be seen wearing Bluetooth headsets to listen to music, whether in public or private places. Excellent sound quality not only brings higher quality music, but also makes the experience of listening to music richer and more enjoyable.
Sound quality is mainly determined by two aspects:
The first is the sound unit. The sound units of Bluetooth headsets mainly include moving coil units and moving iron units.
The volume of the dynamic unit is relatively large, and it needs a certain space for the diaphragm to vibrate, so it can present a richer and more natural sound quality of music, retain more music details, and sound more three-dimensional and transparent. Dynamic units are used in everything from ordinary headphones worth tens of yuan to high-end headphones worth tens of thousands of yuan, and their range of use is very wide. The moving iron unit is small in size and can be easily placed in the ear canal or earmuffs. The materials it uses are more expensive and the sensitivity is also higher.
Secondly, audio encoding audio encoding format is also one of the key factors that determine the sound quality of headphones.
Common audio encoding formats currently on the market include SBC, AAC, apt-X, LDAC, etc. All Bluetooth headsets will at least support the SBC format, which is also the encoding method used in early Bluetooth transmission and can only support mono audio transmission. The AAC format is mainly used on Apple devices. The higher the encoding format, the richer and more dynamic audio details can be transmitted, and the music will sound more three-dimensional and moving. However, a high bit rate encoding format does not necessarily mean that the sound quality will be better. This view is wrong. The actual listening experience also depends on a combination of other factors.
Headphone comfort:
When choosing products that require long-term contact with the body, especially devices that need to be worn like headphones, comfort should be the primary consideration. Only when users feel comfortable and comfortable during use will they start to pay attention to other aspects of performance. Currently, the design of open-type headphones can provide the highest level of comfort, so more and more consumers choose open-type Bluetooth headphones.
However, comfort does not only depend on hardware factors such as the weight, shape, and material of the headset. The actual comfort experience varies from person to person. Because everyone’s ear structure is unique, the discussion and recommendations on the comfort of headphones in this article are for reference only. The specific comfort needs to be determined based on personal trial experience! Therefore, I will include the actual wearing test of comfort in the actual measurement below, which will be more reference.
Headphone battery life:
The battery life performance of earphones can be evaluated from the following aspects:
1. Battery capacity The capacity of the battery directly determines the battery life of the headset. Generally speaking, headphones have low energy consumption, and a battery capacity of more than 50mAh can provide better battery life.
2. Chip power consumption adopts a more energy-saving chip, which can effectively reduce power consumption and improve battery life.
3. The higher the power of the headset, the faster it will consume power. Using reasonable driving power helps save power.
4. Charging speed Fast charging can reduce waiting time, and fast charging technology can fill the battery faster.
5. Bluetooth codecs Although Bluetooth codecs with high bit rates have good sound quality, they also consume a lot of power. Reasonable selection of codec standards is also key.
5. When turning on more auxiliary functions in function settings, more power will be consumed. You can turn off some unnecessary functions as needed.
6. Usage environment In a good Bluetooth connection environment, the headset battery consumes less power.
By comprehensively considering these factors, choosing headphone products with large-capacity batteries, efficient chips, reasonable power output, fast charging, energy-saving codecs, configurable functions, and turning on the control functions will generally lead to better battery life performance.
Headphone connection performance:
The connection stability of the Bluetooth headset refers to whether there will be disconnection or unstable connection during use. The newer version of Bluetooth usually has stronger signal transmission and anti-interference capabilities, so it can bring more reliable and stable connections. The transfer rate determines the audio and data file transfer speed of Bluetooth. Higher versions of Bluetooth generally have faster transmission rates, which is especially important for transmitting high-quality audio signals. The faster the transmission rate, the faster the audio signal can be transmitted to the headset, resulting in better sound quality and user experience. Latency refers to the audio signal travel time from the source device to the headphones.
Newer versions of Bluetooth usually have shorter latency, which is critical for audio and video synchronization and gaming experience. The shorter the delay time, the smaller the time difference between audio and video, ensuring accurate presentation of sound. Therefore, when choosing a Bluetooth headset, you can give priority to newer versions such as v5.0, and choose a chip solution with a good reputation to obtain better connection stability, transmission rate and delay performance.

QCY Crossky GTR open-back headphones
Comments:
QCY is a brand that focuses on cost-effectiveness, but the price-performance ratio of this style is not high. The headphone body is large, the comfort of wearing it for a long time is not good, and the sound quality is not excellent.
Sound quality experience:
The inside of the fuselage is equipped with a 17mm×12mm racetrack-shaped biofilm speaker, which can present richer sound details, full sound quality and good layering, and excellent low-frequency performance. However, the high-frequency quality is poor, the range extension is poor, and there may be a certain degree of sound leakage.
Wearing experience:

It is very stable and comfortable to wear, and it is not easy to fall off even when running outdoors.

Sony Float Run open-back headphones
Comments:
Sony's main sports series of headphones, the body design is still a bit too big for me personally, it is not very comfortable to wear, but it is really impeccable in terms of stability. In terms of sound quality, my personal feeling is that it can only be regarded as a pass, not very good. It is a good choice for running, but there are many similar alternatives, which are not outstanding.
Sound quality experience:
In terms of sound quality, the built-in 16mm large driver unit provides clear vocals and strong stereo effects, while having an excellent sense of rhythm. However, the sound resolution in the high frequency part is not high enough, and the overall experience is mediocre. And there may be some audio leakage issues.
Wearing experience:
Sony Float Run adopts a suspended non-ear design to avoid squeezing the ear canal. This design provides good ventilation and air permeability, ensures a dry feeling during exercise, and effectively prevents ear canal health problems. However, the overall wearing comfort of the headset is not very good, and it is not very compatible with glasses.
Other configurations:
The call quality of the headset is not bad, there is no obvious noise, and the Bluetooth 5.0 version is used. Although it is not as good as 5.1 or above, it is enough for daily use. It brings 10 hours of battery life, can stand by for 200 hours, supports IPX4 waterproof, the sweat in daily life will not damage the interior, and there is no problem with sports use.
JBL Nearbuds open-back headphones
Comments:
The bass performance of JBL's headphones is still strong and powerful, the sound quality clarity is also very good, and the stability is well guaranteed. Unfortunately, the call quality of the earphones is relatively average, and it is not suitable for games or watching videos. There will be a sense of delay, and it is not suitable for games and audio-visual scenes. This is a point that can be improved.
Sound quality experience:
This JBL sports open-back headset performs well. As a sports headset, its bass effect retains JBL's traditional sound and the sound quality is clear. It uses 16mm large driver unit speakers and air conduction technology to transmit audio in specified directions, effectively reducing sound leakage, improving low-frequency sound effects and rhythm, and the midrange performance is also very full, which is generally good.
Wearing experience:
JBL NEARBUDS headphones use lightweight materials, and the entire headphones are wrapped in a skin-friendly liquid silicone, which will not feel hard or irritating to the ears. The ear wings adopt a triangular fixation design for a more stable fit, but the sound cavity of the earphones is large and the comfort is not particularly good.
Other configurations:
In terms of configuration, this headset uses Bluetooth 5.2 technology, which can maintain dual links with two devices at the same time, but the delay of the headset is still high. The headset has a battery life of 8 hours. Although it is not particularly outstanding, it is equipped with a fast charging function that can quickly charge the battery in a short time. In order to ensure the safety of night sports, the headphone ear hooks are also integrated with eye-catching LED warning lights. In addition, the IPX4-level waterproof design also makes this headset suitable for sweaty sports scenes.
cleer arc ll open back headphones
Comments:
Cleer's headphones are available in three versions: sports, gaming and music, and the usage scenarios are clearly differentiated. The earphones have a more technological appearance and are more stable to wear. But comfort is not its strong point. The headphones have clear contours and will cause a certain amount of pain when worn for a long time. If you are looking for comfort, Cleer may not be a good choice.
Sound quality experience:
Supports aptX LL audio coding, lossless sound quality is stronger; it uses a 16.2mm large dynamic unit, equipped with Qualcomm Snapdragon's latest S3 Bluetooth audio new platform, supports Snapdragon Sound technology, and has a CD-level lossless sound quality experience.

Oladance OWS PRO open-back headphones
Comments:
Oladance's new open-back headphones are indeed quite good in terms of sound quality and comfortable to wear. They are a relatively comprehensive style. However, the price of the headphones is on the high side, so those interested in their good looks can also consider them.
Sound quality experience:
Thanks to the built-in laminated speakers and Oladance's self-developed algorithm, OWS Pro headphones present a full and clear sound quality. Although it is a non-in-ear design, the built-in double-layer speaker has two diaphragms and two sets of magnetic circuits, achieving good sound quality restoration in the same volume, with both thick low-frequency volume and excellent tone transparency. The listening experience is rich and shocking, and it is very suitable for enjoying music with strong rhythm and dynamic feeling during exercise.
Wearing experience:
The earphones are made of skin-friendly soft silicone and ceramic skin materials, making it feel as delicate as skin. Wearing it simplifies the structure at the end of the earhook, greatly reducing the weight and foreign body sensation on the ear. The innovatively designed 3.1 arc surface new support structure makes it more comfortable and stable to wear.
Other configurations:
The single battery life of the headset is up to 16 hours, and the comprehensive battery life with the charging box can reach 58 hours. Wireless headsets using Bluetooth 5.3 technology have the characteristics of low power consumption, low latency, and high stability, but they are still slightly insufficient when playing games that require low latency.
Sony LinkBuds open-back headphones
Comments:
One of the particularly compact models in this review is designed to fit into the auricle. The wearing comfort varies from person to person. Personally, I feel a strong foreign body sensation. The sound quality is average, and its main advantage is its portability.
Sound quality experience:
The speaker of this headset is equipped with a new 5mm driver unit and V1 integrated processor to ensure stable transmission of audio signals and reduce distortion. In terms of sound quality performance, the mids and highs are fairly clear, but the bass is slightly flawed. Overall, it's quite satisfactory, but it's no problem for daily use.
Wearing experience:
This headset is made of skin-friendly and high-friction material, and is structurally designed with an internal center of gravity. The open cavity design and adjustable semicircular silicone support frame further improve the stability of wearing. However, the wearing comfort is still uncertain. It depends on whether the inner ear contour shape adapts to it. Personally, I think it is pretty good, and the same is true for the firmness.
Other configurations:
The headset has built-in Bluetooth 5.2 connection technology, and the signal connection is stable; it supports touch operation and is portable and convenient. In terms of battery life, the headset has a single battery life of 11 hours, and the charging box provides an additional 6.5 hours, with a total battery life of 17.5 hours, which can basically meet the needs of daily use.

Seeing this, I believe everyone has a certain understanding of open-back headphones. At the end, I will make some personal purchase recommendations!
First of all, if you have enough budget, I would first recommend this Nanka 00-volt open-back headset. It is this year’s “true flagship” and has full configurations in all aspects. It is not only very comfortable to wear, but also has excellent sound quality and configurations. Comprehensive, it can be said that the purchase will not be a loss at all.
In addition, if appearance is important, you can consider Shaoyin Openfit and Oladance OWS PRO, which are also good models;
If cost-effectiveness is your main consideration, you can choose Nanka OE CC.
Just choose according to your actual needs!
