What is TWS earbuds?

TWS, an abbreviation for True Wireless Stereo, is a technology developed based on Bluetooth chip technology. Its concept involves the mobile phone connecting to the primary headphones, which then swiftly establishes a wireless connection to the secondary headset. This process achieves genuine wireless separation of the left and right channels of Bluetooth.

Key features of TWS earbuds:

Wireless: Eliminating the hassle of tangled headphone wires, TWS Bluetooth earphones operate without a wired connection, providing freedom from traditional earphone constraints. The left and right earphones form a stereo system through Bluetooth, enhancing experiences such as music listening, conversations, and various activities like mountain climbing and running.

Binaural Stereo: Enhancing sound and call quality, the focus on audio and video experience highlights the necessity of noise reduction technology in TWS headphones.

Multiple Perception: Evolving into semi-smart earphones, TWS earphones, in the 2018 development surge, upgraded Bluetooth chips to version 5.0, supporting flexible customer software upgrades and operating experiences.

Compact Size: Comfortable to wear, convenient to use, and easy to carry, TWS headphones prioritize user comfort and portability.

There are now abundant options and intricate decisions when purchasing TWS headphones. The following are some key factors that you can pay attention to when purchasing TWS earbuds.

Audio Decoding Technology:

To improve the listening experience, a variety of audio decoding technologies are used in TWS, the following are some of them.

SBC: A general audio format with average sound quality.

AAC: Offers better sound quality than SBC when both Bluetooth and the mobile phone support AAC format files.

APTX: CSR's patented encoding algorithm, providing high-quality audio with low hardware complexity.

APTX-LL: Focuses on low latency, achieving less than 40ms latency.

APTX HD: Enhances sound quality transmission through increased bit rates.

LDAC: Developed by Sony, supports high-resolution audio transmission through Bluetooth.

LHDC: Independently developed by Huawei, ensures maximum wireless audio transmission resolution and high sound quality purity.

Noise Reduction Technology:

ANC: Active noise reduction using hardware to collect external noise and generate inverted sound waves for sensory noise reduction.

ENC: Environmental noise reduction technology effectively suppresses reverse environmental noise.

DSP: Targets high and low-frequency noise, similar to ANC noise reduction.

CVC: Call software noise reduction technology, primarily addressing call-generated echo.
