Bluetooth headset portability is extremely high, the sound quality and wired headphones are almost no different, in life portable use let me use more and more love. Listening to songs, chasing dramas, playing games, avoiding embarrassment while bringing the ultimate sound experience, the sound immersive feeling is really not too great.
So the question is coming, there are so many headphones on the market, which one is the most suitable for you? How to choose an affordable and easy-to-use Bluetooth headset? So this time also brings ten real reviews of Bluetooth headsets and the final recommendation to everyone
In order to save time, here is a wave of recommendations for everyone, the following introduction of headphones, you deserve to have!
PS: The article is accompanied by purchasing tips and Bluetooth headset knowledge, be sure to read it carefully!
NO.1 South Carolina Lite Pro2 (Look here for the light of domestic goods!) ）
Evaluation feeling: The initial feeling of getting this headset is that it is very comfortable to the touch. Compact body, extremely easy to carry around. The sound quality is extremely comfortable, and it is a high-priced Bluetooth headset that is comparable to the big names on the market. Bluetooth connection is also very convenient, almost can be open cover direct connection, do not need to worry about the left and right ear connection is not connected. Strong waterproofness, sometimes slipping accidentally falling into the basin can also be effectively waterproof, the sound quality is also undamaged. The most important thing is that although the South Carolina Lite Pro2 is a semi-in-ear headphone, it has solved the problem of poor sound quality sealing in terms of research and development, and chasing dramas and listening to music does not affect the sound quality at all. The affordable combination with the all-round function is worth starting.
NO.2 Redmi AirDots 3 Pro
Evaluation experience: unique touch, the appearance of the appearance is also very clean, in the headphone market is refreshing. Cost-effective, basic functions are readily available, and there is still no obvious shortcoming. It is more comfortable to wear, does not raise the ears, and the active noise reduction ability is OK. And after downloading the Xiaoai Classmate app, you can choose between bass enhancement, treble enhancement, vocal enhancement and other modules, as well as fit detection, adjustment gesture operation and other functions. The price of 395 yuan is better equipped with more perfect functions, and overall it is still worth starting with an affordable headset.
NO.3 Huawei FreeBuds 4i
Experience: It is worth mentioning that the single endurance of Huawei Freebods 4i is quite good, although the battery life of the charging case is still slightly weak, but this point will not lose too much experience. But it is worth mentioning that this Bluetooth headset supports fast charging, and it takes only 10 minutes to fill the power for 4 hours. As a whole good evaluation of true wireless noise-canceling headphones, comprehensive price and practicality, it is very recommended for small partners with insufficient budget. Its appearance is simple, and the pure white shell design is simple and generous, which can be started with confidence and boldness.
First, a little knowledge about the parameters of Bluetooth headsets
1. What are the wireless transmission specifications?
SBC: The earliest audio encoding format with low efficiency and high compression, resulting in poor sound quality.
ACC: A high compression ratio encoding algorithm that compares to SBC sound quality.
APTX: A lower latency and transmission bit rate, is a patented encoding algorithm invented by CSR Corporation.
LDAC: One of the best sound quality encodings in Bluetooth encoding is a new wireless audio coding technology introduced by Sony.
Usually the specifications of wireless transmission are linked to the stability of Bluetooth headphones and sound quality effects, and when selecting headphones, pay attention to the headphone configuration specifications in the instruction manual.
2. Frequency response range
A wide range of headphones usually has a good sound quality detail performance, and the wide range of frequency response can well restore the internal sound of the phone.
What is the frequency response range?
The frequency response range of the headset is actually an interval, the larger the number behind, the better the high frequency range it can cover, and the smaller the number in front, the stronger the bass that can be heard in the headphones.
The auditory frequency of the human ear ranges from 20Hz to 20000Hz. But the actual results need to be tested in reality, usually with age, generally people over 25 years old, more than 18000Hz sound is generally not heard, the elderly to the elderly people will even be lower than 8000Hz basically belongs to the hearing impairment of not hearing treble.
3. Impedance
The headphone impedance of the general mobile phone is below 32 ohms. It is worth mentioning here that the impedance of professional headphones is large, which can better protect the headphones and withstand the high-power equipment of the previous stage, on the other hand, the use of better metals, the impedance will also become larger. But the impedance of the Bluetooth headphones we usually use will vary at different frequencies, and the smaller the impedance, the easier it is to drive.
Impedance value: The impedance value of the headphone at 1000HZ
Unit: Ohm
Generally we compare the sensitivity with the impedance, and the impedance has a lower impact on the driving headphones than the low sensitivity.
4. Sensitivity / sound pressure
What is decibel?
The decibel is actually the smallest sound you can hear, for example, there is a noiseless chamber at Microsoft, and the decibel in this place is -20 decibels, which means that the machine can hear but you can't hear. Sound pressure, in layman's terms, is that the sound is not big.
Sensitivity value: The value of the headphone frequency at 1000HZ
Unit: dB/mW (decibel)
Uncommon unit: dB/Vrms (it represents the sound pressure level generated when the 1Vrms voltage is applied to the headphones, referred to as dB/V)
Above 110db is very good to push, and the Basics of the Walkman phone can be fully driven (of course, it may not be able to fully play the ear
Effect of the machine, as above).
Don't look at the difference between sensitivity 110 and 100 is only 10, but the increase in sound pressure level value is not a general linear increase, when the sound pressure increases by 3 dB, the energy of the sound increases by 1 times. For example, when two speakers play 100dB of sound at the same time, the decibel is 100 + 100 = 103, not 200dB!
Second, half into the ear, how to choose in-ear headphones
Common headphones in addition to the head-mounted, plug-in, and true wireless headphones, they have differences in appearance and connection methods, the ear wear part of the headphones is also divided into in-ear and semi-in-ear. The two differ not only in terms of wearing, but also in terms of sound quality and impact on the ears.
Semi-in-ear
The internal structure of the in-ear headphones is composed of moving iron, dynamic coil and piezoelectric structure. The semi-in-ear ear shell is basically outside the ear canal, and the low frequency will have the problem of sound leakage, and the sound insulation effect will be worse than that of the in-ear headphones. The principle is that because the sound is weakened more than after passing through the air, the details of the sound quality become less natural and delicate.
Also because it does not have earbuds into the ear canal, it is comfortable to wear, and there is no pressure on the inside of the ear, which is suitable for daily long-term use.
In-ear
In terms of structure, the in-ear headphones are similar to the semi-in-ear structure, and the internal composition also includes the dynamic coil, moving iron, and piezoelectric structure. The biggest difference between the two is that the ear shell of the in-ear headphones can reach into the ear canal, the low frequency is stronger, the sound insulation effect is better, and the sound quality experience is better.
However, because in-ear headphones are equipped with earplugs, they will form an oppression on the ear canal, and if they are worn for a long time, the ears may be swollen and painful, resulting in the complication of ear diseases such as otitis media. Friends with sensitive ear canals choose carefully!
For in-ear and semi-in-ear options, be sure to start from the personal body ear comfort, choose headphones that fit your ears, and experience comfortable sound quality without getting yourself hurt.
Third, choose a good Bluetooth headset must-see option
1. Connection stability
The connection stability of Bluetooth is usually related to the radio spectrum, transmission power, and receiver sensitivity.
The lower the frequency of the radio spectrum, the longer the transmission range. The power emitted is similar to your volume, the louder you speak, the more clearly you can be heard by standing in the distance, and the more energy you need to consume. In terms of transmit power, the higher the transmit power, the farther away the signal can be transmitted, and the farther its effective transmission range. Similarly, the increase in transmit power also brings high power consumption of the device. The sensitivity of the receiver is similar to the minimum volume you can hear, and the popular understanding is the clarity of the minimum sound that can be heard. It is a measure of the minimum signal strength that a receiver can measure, and the receiver is critical to being able to detect radio signals and maintain connectivity.
The three complement each other and jointly support the connection stability of Bluetooth headsets.
2. Comfort
The wearing experience of the headphones is equally important. A good headset is extremely comfortable, and the ear plugs conform to the contours of the ears not only bring the experience of sound quality, but also bring about the improvement of physical comfort. Ear plugs of skin-friendly materials often do not cause inflammation in the ear, have good breathability, and do not form a large pressure in the ear. After use, there will be no pain inside the ear, a feeling of pressure, and other undesirable feelings. At the same time, a reasonable headphone design will not fall frequently when moving.
At the same time, you can choose headphones without a sense of weight, which can allow us to wear headphones for a long time but do not feel the burden, if the headphones and their ears fit well, to reduce the problem of sound leakage to obtain a fuller music experience effect. The high-comfort headphones can even fit your ears completely, and the skin feel is extremely strong.
3. Sound quality
When it comes to sound quality, we have to mention three important components: the sound unit, the dynamic unit and the moving iron unit.
Common sense knows that sound is produced through the vibration of objects. The sound of the erhu comes from the vibration of the hu strings, the sound of the big drum comes from the vibration of the drum surface, and the sound of singing also comes from the vibration of the vocal cords.
For Bluetooth headsets, to produce sound, the internal components also need to vibrate, and the part of the headset responsible for vibrating sound is also the sound unit. The dynamic unit is similar to a human, so it is more comfortable and natural to hear. The most common example of the moving iron unit is the principle of the use of hearing aids is the moving iron unit. The sound principle of moving iron headphones is also through magnetic strength and direction to produce vibration, but unlike the dynamic unit, the magnet is replaced by an electromagnetic, and the diaphragm is replaced by an iron sheet.
When you want a headset with good sound quality, distinguish which of the three headphones you choose belongs to. Each of the three has its own points, and must be selected according to your actual needs.
4. Battery life
The battery life of the Bluetooth headset refers to the continuous use time of the Bluetooth headset after it leaves the cabin. The general Bluetooth headset is used for 3-4 hours. So how long is the most suitable battery life as a normal Bluetooth headset? As a user, it must be the longer the better, but because the advantage of Bluetooth headphones is small, so the increase in battery capacity, headphones are difficult to have a small body shape. In terms of general usage habits, mainstream wireless headphones must meet the needs of a day's use. In terms of the longest period of continuous use, 8 hours is a credible length of time. Too long use time will not only have a loss of headphone performance, but more importantly, it will also have some damage to our hearing, so we must choose carefully in terms of battery life.
Bluetooth headset evaluation encyclopedia
1. Connection stability test (knock on the blackboard focus!) ）
Every time I buy a new Bluetooth headset, I can't wait to try it out, but once I get away from the phone, the sound will become intermittent! Really angry!
I believe that in reading this article, you must have encountered such a problem, I have to say that the stability of Bluetooth headsets is closely related to the experience of headphones. Good stability is that no matter how far away you are, as long as you are within the normal range, you will get a stable music experience, but bad stability will drive you crazy. When buying Bluetooth headsets, be sure to check the compatibility of the headset with the mobile phone, and test the call quality of the mobile phone in time after buying it back. Usually indoor Bluetooth headsets transmit signal signals at a straight-line distance within 10 meters, so this time these ten Bluetooth headsets will be tested for the connection stability of the open cover. (50 lid opening connections per model)
Stability Ranking:
Level 1: South Carolina Lite Pro2, Samsung Buss2, Xiaomi Air 2 Pro, FIIL CC 2, Jetbra Elite75t
Level 2: Huawei FreeBuds 4i, Redmi AirDots 3 Pro, Wanderer Lollipopds Pro, Vivo TWS 2
Level 3: OPPOenco X
2. Sound quality
The direct purpose of buying headphones is to have a good sound quality experience.
Take the analogy of buying a mobile phone, buying a good mobile phone can have a more accurate visual experience, while a good headset has a clearer sound quality effect. Good headphones will make you immersive, listening to the flowing water like on the side of a river; watching blockbusters to deepen the shocking experience; and when you exercise, the clear sound quality will stimulate your physical functions and give you motivation to move forward. So, choosing a headset with the best sound quality is a must-have. Therefore, the test is connected to the headset by the mobile phone to play the music, and then the headset is worn to the head recording tool, and the music can truly feel the sound quality taste of the more public.
Sound Quality Ranking:

Level 2: Huawei FreeBuds 4i, OPPO enco X, Sonic Air2 Pro, FIIL CC 2, Vivo TWS 2
Level 3: Redmi AirDots 3 Pro, Wanderer Lollipopds Pro
3. Comfort test
I believe that students who have bought Bluetooth headsets must have an understanding of the comfort of headphones, a Bluetooth headset has the best sound quality and noise reduction ability, wearing discomfort is also very uncomfortable! Therefore, when purchasing, we must take into account the weight of Bluetooth headsets and the skin-friendliness of the materials.
Comfort Ranking:
Level 1: South Carolina Lite Pro2, Wanderer Lollipopds Pro, Vivo TWS2, OPPO enco X
Level 2: Huawei FreeBuds 4i, Samsung Buds2, Sonic Air2 Pro, FIIL CC 2
Level 3: Redmi AirDots 3 Pro, Jetbra Elite75t
4. Delay
Usually, when Bluetooth transmits signals, it needs to go through four links: compression packaging, wireless transmission, disassembly and decompression, and digital-to-analog conversion. Throughout the process, Bluetooth transmits wirelessly at the speed of light, and theoretically there is no delay problem. But in fact, so far, Bluetooth technology has not achieved true zero latency. The delay effect is also directly related to the processing speed of Bluetooth encoding. Therefore, this time we will use the Latin Test delay test software to conduct a delay test on each headset (the lower the delay, the better)
Latency Leaderboard:
Level 1: South Carolina Lite Pro2, Samsung Buss2, Redmi AirDots 3 Pro, Jetbra Elite75t
Level 2: OPPOencoX, Huawei FreeBuds 4i, Wanderer Lollipopds Pro, Vivo TWS2
Level 3: Sonic Air2 Pro, FIIL CC 2
5. Endurance test
An excellent Bluetooth headset jun will definitely have a better endurance. For endurance, everyone may think that it refers to how long the Bluetooth headset can last after wearing. But in fact, the endurance includes the word endurance of the Bluetooth headset and the endurance of the whole aircraft. In addition, the charging chamber charging time of Bluetooth headsets should also be paid attention to, and the charging compartment that is charged for too long is not only difficult to use, but also extremely time-consuming.
In terms of the current degree of use of the public, as long as the total battery life reaches more than 30 hours, it can meet the needs of everyone. In order to test a more realistic endurance, you can only use the time-consuming headphones to connect the phone to play the same music, the same volume to test.
Endurance Ranking:
Level 1: South Carolina Lite Pro2, Redmi AirDots 3 Pro, OPPOencoX, Vivo TWS2, Sonic Air2 Pro
Level 2: Huawei FreeBuds 4i, Samsung Buss2, FIIL CC 2
Level 3: Wanderer Lollipopds Pro, Jetbolon Elite75t
Summary: The above assessment options can be decided according to the actual needs of their own purchase, do not blindly start, choose the most suitable for yourself!
