What chip is good for bluetooth headset?

At present, the main chip brands on the market can be divided into four categories:

1. Apple’s self-developed H1 chip, used in AirPods series products, supports voice operation function, can call out the Siri of mobile phones, and has excellent performance in terms of delay.

2. Qualcomm series chips, which occupy the mid-to-high-end chip market, have unique aptx technology, efficient coding, more details of sound retention, and greatly improved delays. The representative models are QCC3020, CSR8675, etc.

3. Taiwanese manufacturers; Luoda, Hengxuan, Realtek, etc. Among them, Luoda is a brand with a large market share in the current Bluetooth audio market, with representative models such as 1536U, which is known as the “Shen U” of Huaqiangbei AirPods; the next is Hengxuan BES and Ruiyu, currently many domestic Large manufacturers are using the BES23 series for development.

4. Manufacturers such as Zhuhai Jerry and Zhongke Lanxun produce chips that are mostly found in Huaqiangbei AirPods, with huge shipments.

The CSR solution is used more on high-end Bluetooth headsets, with stable sound quality, 5-band tuning, and low power consumption. The disadvantage is that the noise floor is more difficult to control. Many manufacturers develop this solution, but usually the noise floor is not well controlled.

Texas Instruments (TI) and Zhuhai Actions program, Bluetooth headsets are not used much, and the sound quality is not bad. And the Actions solution has a very big advantage, the noise floor of the chip itself is super small. The Bluetooth headset developed on this platform can achieve almost zero noise floor with technologies such as filtering noise cancellation and algorithm noise cancellation. For example, the HIK X1 Bluetooth headset adopts the Actions solution, and the noise floor is very small.

Luoda is mainly used to imitate Apple headphones, the sound quality is acceptable, but some functions cannot be customized, which is relatively rigid. Jianrong and Jerry needless to say, listen to the series. 19.9 free shipping is it.

But whether a Bluetooth headset product is good to use, you can’t just look at the chip solution. Peripheral circuits, tuning, and software debugging are all indispensable.
