In December 2019, West Fountain and Shenzhen Capital Group completed C+ round investment in Bestechnic, a wireless intelligent SoC chip company. Prior to July, Bestechnic had just completed Series C led by Xiaomi Yangtze River Industry Fund and Alibaba Group, along with IDG and many others.

Bestechnic was established in early 2015. The core members are from well-known domestic high-tech companies, focusing on the development and sales of RF SOC chips for wireless audio platforms, providing customers with audio system-level chips with WIFI/BT wireless connections. , Software and hardware development kits and complete reference design solutions to help customers quickly launch industry-leading wireless smart products.

As the leading domestic TWS wireless headset chip, the BES2000 chip launched by Bestechnic is highly regarded in the mid-to-high-end TWS Bluetooth headset solution. The performance of the wireless headset products imported into Huawei is very good. Bestechnic has also become a major supplier of TWS Bluetooth headset chips. .



BES2000 is a new generation of fully integrated adaptive dual-mode Bluetooth headset solution with full integration, high performance, low power consumption, etc., supports Bluetooth v4.2 standard, supports Hi-Fi audio up to 192KHz/24bit, and supports EQ as well as various sound effect technologies such as heavy bass enhancement. The audio output signal-to-noise ratio is as high as -105db, and the scalability can support adaptive active noise reduction.

BES2300 is a fully integrated adaptive active noise reduction solution that supports Bluetooth 5.0, LBRT low-frequency forwarding technology and dual-mode Bluetooth 4.2. It also supports the third generation FWS full wireless stereo technology, dual microphones, etc., using 28nm HKMG CMOS process, BGA Package.

BES2300 supports noise reduction technology, especially high-performance adaptive active noise reduction technology, which allows high-end active noise reduction headphones to use a fully integrated chip to achieve high sound quality and active noise reduction.

In addition, BES2300 also supports external sensor devices such as heart rate sensors, acceleration sensors, and eMMC flash memory, which can achieve the purpose of playing music on external storage devices. BES2300 can output sound to headphones and home audio and can also record from an external microphone.

The BES 3100 stereo digital codec chip supports up to 96kHz 24bit decoding rate and meets the Hi-Res sound quality standard; it adopts a fully independent balanced output mode for left and right channels and microphones, with a distortion degree of -84dB and a signal-to-noise ratio of -100dB. Excellent sound quality experience for users.


BES 3101 is a main control chip that supports active noise reduction, supports Hi-Res audio decoding; supports multi-terminal EQ adjustment, echo cancellation and bass enhancement; supports USB Type-C digital audio input.

At present, the BES 2000 series of chips have been widely recognized by the market, and brands such as Huawei, Meizu, and Wanmo have adopted them for many times. There have been more than 30 application cases on the market; the BES 3000 series of chips are second.

The rapid increase in volume of TWS headsets has brought incremental opportunities for companies related to the industry chain, among which the most important supply chain manufacturers are chip manufacturers. The original domestic audio chip factory represented by Bestechnic has already occupied a certain share in the explosive audio market, and has been adopted by large customers including Huawei, Xiaomi, OPPO, JBL and other well-known brands at home and abroad. Bestechnic is expected to become domestic audio Chip leader.ng with IDG funds and other investment institutions.
