Active noise reduction in ear TWS consumer headphone speaker

In the fast-paced modern life, people's demands for audio devices are increasing day by day. Active noise cancellation in ear TWS (true wireless stereo) consumer headphone speakers have become a favorite among many consumers due to their superior performance and convenient use. It brings users an immersive music experience and effectively isolates external noise, allowing people to find their own peaceful corner in the noisy world. Next, let's delve into the charm of this product.

1、 Technical principle: The mystery of active noise reduction

Active noise reduction technology is the core highlight of these headphones. Its principle is based on the interference cancellation theory of sound waves. The built-in microphone of the headphones will collect external noise signals in real time, and then generate sound waves with opposite phase and the same amplitude as the noise through a specialized noise reduction chip. When these two sound waves meet in the air, they cancel each other out, thus achieving the effect of reducing external noise. For example, when there is a continuous low-frequency buzzing sound coming from the outside, the noise reduction system of the headphones will quickly respond and generate corresponding reverse sound waves, greatly weakening the buzzing sound and making it almost inaudible to the user.

Compared with traditional passive noise reduction (mainly reducing noise through physical barriers of earplugs), active noise reduction technology has significant advantages. Passive noise reduction is effective in blocking high-frequency noise, but often falls short in dealing with low-frequency noise. Active noise reduction technology can effectively handle noise of different frequencies, especially performing well in the low frequency range. It can reduce low-frequency noise by 20dB or even more, creating a quieter listening environment for users.

2、 Product Features: Integration of Comfort and Convenience

The earphones are designed ergonomically, carefully crafted with the shape and material of the earbuds. The soft silicone earplugs fit snugly against the ear canal, without any noticeable pressure, ensuring comfort even when worn for extended periods of time. Moreover, multiple sizes of earplugs are usually provided, and users can choose the appropriate one according to the size of their ear canal, ensuring that the headphones are securely worn in the ear and not easily dropped off.

True wireless connection: TWS technology achieves complete wireless connection between the left and right channels of headphones, freeing them from the constraints of traditional headphone cables. Pairing with the device via Bluetooth makes the connection process simple and fast. Generally speaking, after successfully pairing headphones for the first time, when using them again, simply open the charging case and the headphones will automatically connect to the paired device, making it convenient for users to use them at any time. The continuous upgrading of Bluetooth technology, such as Bluetooth 5.2 or even higher versions, has brought more stable connections, faster transmission speeds, and lower power consumption. The connection range has also been significantly improved. In open environments, the effective connection distance can reach 10 meters or even further, and users can freely move within a certain range without worrying about signal interruption.

Charging and battery life: Active noise cancelling in ear TWS earphones are usually equipped with a charging case, which is convenient for storing the earphones and can provide additional power for the earphones. Headphones can be quickly charged in the charging case, usually taking 15-30 minutes to meet the user's 1-2 hour usage needs. The charging case itself also has a large battery reserve, which can charge the earphones multiple times. For example, some headphones paired with a charging case can have a total battery life of 20-30 hours, which can meet users' needs for several days even with frequent use, greatly reducing users' battery anxiety.

3、 Sound Quality Performance: Restoring the True Beauty of Music

Driver unit: The headphones use large-sized driver units, such as 10mm, 12mm, or even larger. Larger driving units can produce stronger sound, especially in the low-frequency range. For example, when playing music with a strong sense of rhythm, a large-sized driver unit can make the bass deeper and more powerful, with clear and distinguishable drum beats, providing users with a stunning auditory experience. At the same time, the material of the driving unit is also crucial, and common ones include bio fiber composite diaphragms, titanium coated diaphragms, etc. The bio fiber composite diaphragm has good rigidity and flexibility, which can restore the details of sound while ensuring the natural and authentic sound; Titanium coated diaphragm can effectively enhance the ductility of high frequencies, making high notes clearer and brighter.

Audio Encoding and Decoding Technology: Supports multiple high-definition audio encoding and decoding formats, such as AAC, aptX, LDAC, etc. The AAC format balances sound quality and compatibility, providing good sound quality for most devices; The aptX format has the characteristics of low latency and high sound quality, making it particularly suitable for watching videos and playing games, ensuring audio and video synchronization; The LDAC format is capable of transmitting nearly lossless audio quality, allowing users to hear more details in music as if they were in a recording studio. Through these advanced audio encoding and decoding technologies, headphones can largely restore the original style of music, allowing users to feel the emotions that music creators want to express.

4、 Call quality: Clear communication without interference

Microphone configuration: To ensure call quality, headphones are usually equipped with multiple microphones. Generally, dual microphone or triple microphone systems are used, with one microphone used to capture the user's voice and the other or two microphones used to capture external environmental noise. Through microphone array technology, it is possible to more accurately locate the user's voice while effectively reducing external noise interference. When making a call on a noisy street, multiple microphones work together to clearly pick up the user's voice, while significantly reducing surrounding noise such as car and human voices, allowing the other party to hear the user's speech clearly.

Call noise reduction algorithm: Combining advanced call noise reduction algorithms to further improve call quality. These algorithms can perform real-time analysis and processing on the collected sound signals, separate the user's voice from environmental noise, and reduce the noise. Some headphones also use AI intelligent noise reduction algorithms, which can automatically adjust noise reduction strategies according to different environmental scenarios, providing users with a clear call experience whether it is outdoors with howling wind or bustling shopping malls.

5、 Intelligent interaction: convenient operation, easy control

Touch operation: The headphones achieve multiple operation functions through touch sensing. Users only need to gently touch the surface of the earphones to complete operations such as playing/pausing music, switching songs, adjusting volume, answering/hanging up calls, and waking up the voice assistant. For example, double clicking on the earphones can answer calls, long pressing can activate the voice assistant, the operation is simple and intuitive, and the earphones can be easily controlled without taking out the phone. Moreover, the sensitivity of touch operation has been carefully calibrated, which can accurately recognize the user's operation intention without causing erroneous operation due to accidental touch.

Voice assistant support: Deep integration with mainstream voice assistants such as Siri, Xiaoai Tongxue, Xiaodu, etc. Users can use voice commands to enable the voice assistant to complete various tasks, such as checking weather, setting reminders, playing specific songs, etc. When driving or busy with both hands, the support of voice assistants is particularly convenient. Users only need to say commands, and the headphones can convey them to the voice assistant and perform corresponding operations, truly realizing convenient intelligent interaction.
