Chapter 1 .What’s TWS earbuds 

Since the removal of 3.5mm jack from the iPhone 7 ,the Bluetooth market has developed crazily ,and the types of Bluetooth earphone have emerged in an endless stream especially a TWS wireless Bluetooth earphones,which makes consumers confused ,what’s a TWS earphone ?

You need know something about TWS Technology when refers to TWS Bluetooth headset .TWS is short for True Wireless stereo ,meaning true wireless stereo ,the implementation of this technology is based on the development of chip technology .Technically ,it means that the mobile phone is connected to the main speaker through the connection of the main speaker through Bluetooth wireless connection from the speaker ,realizing the wireless separation of real Bluetooth left and right sound channels .when no connection is made from the speaker ,the main speaker returns to the monophonic sound quality .The technology of TWS has been applied to the filed of Bluetooth headset ,which has spawned a new product ,the TWS Bluetooth headset .

Then how TWS earbuds work ? it’s quite interesting ,I am sure its wireless function really captured people’s attention when compared with other earphones .it offers people a life of wireless and get rid of cable ,how amazing it is ! 

Let’s figure out how true wireless earbuds work .

TWS headphone

It’s same like the traditional wireless headphones ,true wireless headphones receive a Bluetooth signal from your phone via 1 2.4GHz wavelength .the path of transfer renders your phone a transimitter and the earbuds receivers .Unlike typical wireless earbuds –which receive the signal simultaneously since the earbuds are connected by wire—truly wireless earbuds designate one earbud as the primary receiver ,the other becomes the secondary receiver .

Chapter 2 The advantage and disadvantage of TWS Earbuds 

TWS earbuds features a Bluetooth headset and has a charging box .you can use the charging box to charge your earbuds .

Compared to the Bluetooth earphone ,the advantage of TWS earbuds is quite obvious 

1.    Without cable ,truly wireless .
2.    Share and enjoy music with each other ,make life more romantic 

Because the TWS Bluetooth headset does not require a cable connection ,the two sets of headphones make a sound system through Bluetooth ,listening to songs ,phone calls and wearing all the way up,and soon ,it’s very popular among business and young people .However its price quite expensive compared with common Bluetooth earphone .

It comes with a charging box to charge the earbuds at any time ,which easily lost .so you may need a earbud case to keep it in your bags or pouches .

Chapter 3 Price for TWS earbuds 

It’s not hard to find price for TWS earbuds on different platform ,you will quickly find the price is quite different but the design looks similar .It’s no doubt that price varies much due to different feature and quality .

Price ranges from 9-20usd ,this is because the chip /battery and sound quality is quite different . This is similar to the mobile phone’s CPU. The type of CPU the phone has determines its price.

For example, the price of a mobile phone with the CPU of Snapdragon 845 may be around $450, while the price of a mobile phone with a CPU of Snapdragon 660 may be only around $220.

Currently, the main Bluetooth headset chip manufacturers in China are as follow,we will summary for your reference and we will also amylase the main chip’s advantage .then you can make a compare when purchase .

BCM43436 Mono Bluetooth Audio Chip


Cypress recently launched a new Bluetooth audio product to provide a leading performance experience for users of wireless headphones and hearing devices. This solution is based on wireless audio stereo synchronization (WASS) application and CYW20721 Bluetooth and low power Bluetooth (BLE) audio MCU. It can provide a very stable and reliable wireless connection for wireless headphones and enable users to enjoy a differentiated performance experience.

Compared with other TWS true wireless schemes, the link budget of Cypress WASS scheme is 6 dB higher, which is equal to doubling the effective transmission distance. Longer transmission distances and the addition of WASS applications mean stronger "wearing" performance. Even if smart devices are placed in the back pocket or worn on the wrist, users can also enjoy an uninterrupted headphone audio experience. At the same time, the power consumption of the chip is 50% lower than that of similar products, thus doubling the playback time or reducing the size of batteries, making it possible to design and manufacture lighter devices.

The WASS software used in the highly integrated CYW20721 chip is the product of innovations in headphones, mobile devices and virtual reality over the past 15 years. In addition, multi-mode Bluetooth/BLE MCU also provides a number of important functions for consumers, such as language control, cloud-based voice services.
