WHAT IS TWS EARBUD?

Since the mainstream flagship mobile phones have successively cancelled the headphone jack, TWS headphones have become the category of headphones that consumers pay attention to. So what exactly are TWS headphones? What are its characteristics? And how does it achieve active noise reduction? Let me take you to understand it easily.

1. What are TWS headphones?
The full name of TWS is True Wireless Stereo, which means true wireless stereo. TWS technology is developed based on Bluetooth chip technology. Its working principle means that the mobile phone is connected to the main earphone, and then the main earphone is quickly connected to the auxiliary earphone by wireless means, so as to realize the true wireless separation of the left and right channels of Bluetooth.

2. What are the main features of TWS?
The main features of TWS earphones are:

(1) True wireless: get rid of the trouble of entanglement of headphone wires
The WS Bluetooth headset does not require a wired connection, which is free from the shackles of traditional headsets; the left and right two headsets form a stereo system through Bluetooth, which improves listening to songs, calls, and wearing. If you add professional acoustic pickup technology, intelligent noise reduction technology & AI algorithm noise reduction technology, etc., you can achieve a perfect sound experience: ear-worn voice, video calling, music enjoyment, climbing and running, safe driving, etc. are not bound .
(2) Binaural stereo: Improve sound quality and improve call quality
From the product point of view, the audio and video experience is the focus of most users’ attention on TWS headphones, so the noise reduction function is an indispensable technology for TWS

3. How do TWS headphones achieve active noise reduction?
There are three main types of active noise reduction technology in the current TWS headset market, Among them, the working principle of ANC noise reduction is to collect external environmental noise through the microphone. The system transforms an inverted sound wave according to the collected noise and adds it to the speaker end. The final sound heard by the human ear is the ambient noise + the inverted ambient noise. , the two kinds of noise are superimposed to achieve sensory noise reduction. It can be divided into feedforward active noise cancellation and feedback active noise cancellation, and hybrid active noise cancellation. However, feedback active noise cancellation is prone to cause howling.
