Qualcomm technology released the scene and witnessed the new generation of TWS true wireless headphones. This new technology allows the TWS True Wireless Bluetooth Headset to allow two headsets to be connected directly to the outgoing device, rather than being transmitted to the primary headset as before and then synchronized by the synchronization between the primary and secondary headsets. This greatly reduces the delay and deviation of the overall transmission process. Looking back, the Qualcomm CSR8670 chip has laid a solid foundation for this technology.
Bluetooth technology has emerged as a veteran wireless transmission technology for many years. Because of its short transmission distance, people's impression of Bluetooth has not been very good, especially the current situation of smart home speculation. It is inevitable that people will compare various wireless transmission technologies. Everyone has the highest voice for WIFI and zigbee, and Bluetooth seems to have been buried by the times. In fact, after Bluetooth 4.0 came out, is it still like this?
People's understanding of Bluetooth technology is traditionally a technique for short-distance transmission. After the advent of Bluetooth 4.0, this has changed a lot. The traditional 10 meter distance is already a past tense, and now 50 meters is enough for most applications. Traditional one-way transmissions are now also replaced by dual-mode transmissions.
The Qualcomm CSR8670 is a powerful, flexible, and highly integrated wireless audio solution from Qualcomm with many advanced features available. For example, support up to six digital microphones and capacitive touch controllers to develop a wide range of innovative consumer audio devices; Qualcomm CSR8670 can save manufacturers up to 60% printing thanks to lightweight packaging solutions and reduced demand for external passive components Board space for minimal production costs.
By integrating support for capacitive touch sensors, the Qualcomm CSR8670 helps to create a smoother touch interface and a more pleasing product. The trackpad can be set to slide or swipe operation. The touchpad is fully controlled by software, which makes it easy to set up individual applications.
The Qualcomm CSR8670 includes all the features of the Qualcomm CSR8645. But the Qualcomm CSR8670 does not use a ROM-based solution, but instead uses embedded flash memory, enabling OEMs to design their own custom software and unique features using CSR software development kits, CSR eXtension partner solutions and custom software. To achieve maximum product differentiation. Qualcomm Qualcomm CSR8670 Bluetooth SOC. The internal charging function eliminates the need to configure an external charging IC.
The BRAGI The Headphone TWS Bluetooth headset from BRAGI in Germany does not have a built-in battery design in the battery compartment. It directly charges the headset with a 5V voltage input from the USB to the battery compartment. This TWS true wireless Bluetooth headset is equipped with Qualcomm CSR8670 Bluetooth SOC with built-in charging function, which greatly reduces the number of originals on the headset motherboard, making direct charging possible, and exploring a new way of existence of TWS true wireless Bluetooth headset.

In terms of performance, the Qualcomm CSR8670 is also excellent. The Qualcomm CSR8670's dual-core architecture includes an application processor, an ultra-low-power Kalimba DSP, and embedded flash memory, making the CSR8670 a very flexible solution for highly differentiated products. The ABCO enhanced Kalimba DSP coprocessor can perform various signal processing functions simultaneously while receiving data. The receiving method can be any of the following: wireless, digital or analog audio streams.
CSR's full suite of CSR8600 product line setup tools and audio development kits (ADK) for CSR8670-based product design enable manufacturers to develop highly differentiated, feature-rich solutions for wireless or wired consumer audio applications. There is no need to spend a lot of effort on software and hardware development.
Through the eXtension Partner Program, Qualcomm will provide a number of third-party audio enhancement software plug-ins for the Qualcomm CSR8670's on-chip DSP, which will help consumer electronics manufacturers choose from a wide range of solutions and enjoy the benefits. This further shortens the product design cycle. From the above technical parameters and scope, the practical application of the Bluetooth chip is very reliable and extensive, and can be said to be the strongest king configuration of the Bluetooth chip. Qualcomm has introduced the Qualcomm CSR8675 for the current high-end audio files that are becoming more and more popular, and the supported audio bit depth has been increased from 16bit to 24bit, and there are other improvements.
