Real Bluetooth headsets are rotten on the street today, except for the same price, have you noticed product features other than wireless? When every wireless Bluetooth headset is saying that it is true wireless Bluetooth, I can't help but sigh, which one is right for you?
TWS is the abbreviation of True Wireless Stereo, which means true wireless stereo. The implementation of this technology is based on the development of chip technology. Wired headphones can now get rid of the line and become wireless headphones! Technically speaking, it means that the mobile phone is connected to the main speaker, and then the main speaker is connected to the slave speaker through Bluetooth wirelessly, so as to realize the true wireless separation of the left and right channels of Bluetooth. In September 2016, Apple released the first generation of AirPods, opening the era of wireless headsets. TWS headsets usher in unprecedented development opportunities.
When true wireless Bluetooth headsets of varying prices continue to emerge, the factor that most affects our purchase is the sound quality from beginning to end. In the product introduction of many TWS headsets, you can often see "support AptX audio decoding" The selling point, in fact, Apt-X, SBC, AAC, and LDAC are the main centralized audio decoding formats in Bluetooth technology.
The code rate from low to high should be SBC>ACC>APTX>LDAC, where APTX is a patented coding algorithm of CSR. After being acquired by Qualcomm, APTX has been widely promoted in Android phones, so it requires higher sound quality. Friends must pay special attention to audio decoding.
The TWS headset experience is getting better and better. In addition to the powerful audio decoding performance, the noise reduction function is also a very important point. CVC and DSP are the two most common noise reduction functions of TWS headphones:
DSP is the abbreviation of English (digital signal processing), and its working principle: the microphone collects external environmental noise, and then through the noise reduction system function inside the headset, it copies and generates a reverse sound wave equal to the external environmental noise, canceling the noise, and achieving Better noise reduction effect.
CVC is the abbreviation of English (Clear Voice Capture) and is a software noise reduction technology. Its principle is to suppress various types of reverberation noise through the noise reduction software and microphone built into the headset.
Below, I will share some practical Bluetooth headsets for everyone:
Hit F1
The F1 has a small and round appearance, with a single weight of less than 4g. It is comfortable to wear and has no weight. The charging compartment adopts pure white color, and it feels warm and moist. In order to achieve overall consistency and aesthetics, the charging port is set under the charging compartment, and a type-c charging interface is adopted. The headset has 3 sound effect modes, which can be switched by pressing and holding the touch area for 4 seconds: in game mode, the delay is as low as 0.04S, which is 2-3 times that of the traditional mode, and it also comes with "listen to sound position" in game mode , 3D surround immersive experience, easy to eat chicken is not a dream; in music mode, high-definition audio acceleration decoding, with graphene ultra-thin high-elastic diaphragm, EQ intelligent adjustment of sound effects, enjoy pure sound quality at any time; in audio-visual mode, immediately accelerate the picture and audio Synchronization, whether it is Blu-ray or 8K, it can synchronize audio and video, and enjoy the original sound effects of large movies.
F1 also uses Bluetooth 5.0 chip, which has the characteristics of fast transmission rate, long distance, and strong anti-interference ability. Compared with the 4.2 Bluetooth version, each performance is improved by more than 2 times. Coupled with DSP+CVC 8.0 call noise reduction technology, the noise can be physically reduced, allowing users to maintain clear calls in noisy environments.
Compared with traditional true wireless, the battery life is doubled. A single battery life can reach 8 hours. With a charging compartment, it can reach up to 35 hours. It is compact and has such a powerful battery life. Why? Because F1 uses a 6-layer intelligent energy-saving protection board, with a 360 mAh "Tesla" pure cobalt lithium battery for the car, it saves power consumption and improves the life of the headset battery.
Edifier Funbuds
In appearance, the overall appearance of Fun Buds interprets the design concepts of simplicity, fashion and advanced. Fun Buds is equipped with an upgraded version of ambient sound listening mode, which allows you to perceive ambient sound without removing the earphones. Not only can you clearly hear the conversations of passers-by, you can also hear all traffic sound information without removing the earphones when traveling outdoors. The Fun Buds sound quality is equally awesome, the headset is equipped with a 10mm composite diaphragm unit, providing excellent audio resolution. On the other hand, Fun Buds supports IP54 dustproof and waterproof, and can easily resist the intrusion of rain and sweat. Running outdoors on rainy days and sweating in the fitness room are your close friends.
Huawei FreeBuds Pro
FreeBuds Pro is fully functional, dynamic noise reduction, touch control, wireless charging, including fit testing, etc., it has the functions of wireless earplugs. The appearance is very novel, with a square design, which is highly recognizable. In terms of hardware configuration, Huawei FreeBuds Pro adopts an in-ear design, which can achieve a certain noise reduction effect by itself. It also benefits from three high-sensitivity microphones, an 11mm large amplitude steady-state dynamic coil and a bone With high-quality acoustic components such as voiceprint sensors, Huawei FreeBuds Pro wireless headphones can accurately pick up external environmental sounds and achieve the ultimate noise reduction depth of 40dB. The battery life is also excellent. Huawei FreeBuds Pro itself has a long battery life. With noise reduction turned on, the headset can play 4.5 hours of music.
Xiaomi Air2S
The appearance of Xiaomi Air 2S has not changed significantly. The earphones are made of the same matte white plastic and the manufacturing quality is the same as that of its predecessor. The weight of each earphone is about 4.5g, and the body is very light. It adopts a semi-in-ear wearing structure and is equipped with an infrared sensor. When any earphone is taken out of the ear, the sensor will pause the music playback. Resume music playback. It uses a Bluetooth 5.0 dual-core chip and uses binaural synchronous transmission technology to simultaneously transmit sound waves to the left and right earphones. The LDHC Bluetooth decoding module is also optimized for the MIUI system, which can further capture the new architecture.
OPPO Enco W31
OPPO Enco W31 true wireless headset has a built-in Bluetooth 5.0 chip for binaural transmission to ensure a more stable and smooth connection, and supports single/binaural use. Whether it is watching videos or playing games, users will no longer suffer from disconnection and delay Trouble, enjoy fun anytime, anywhere. The headset uses dual TPU composite graphene diaphragm speakers, effectively improving high-frequency extension and low-frequency diving, and supports AAC high-definition audio encoding and SBC audio format, with higher resolution, restoring music details, and presenting high-quality audio for users who are pursuing sound quality. Music feast. OPPO Enco W31 has built-in equalization mode and dynamic mode, users can freely choose according to their listening habits and the type of audio source.
