TWS headset solution based on Qualcomm S7 Pro Gen 1 platform

In the Bluetooth audio product market, Qualcomm platforms are the first choice for high-end products in this field. As an indicator leading the market development trend, Qualcomm recently pioneered the new generation flagship platform Qualcomm S7 Pro Gen1, which combines high performance, low power computing, terminal-side AI and advanced connectivity. It opens a new era of audio innovation and creates a breakthrough user experience. It sets a new benchmark for high-performance audio with ultra-low power consumption.

The first-generation Qualcomm S7 and S7 Pro platforms leverage unparalleled levels of on-device AI to create an advanced, personalized, and responsive audio experience.

The computing performance of the new platform is 6 times that of the previous generation platform, and the AI ​​performance is nearly 100 times that of the previous generation platform. It brings a new level of ultra-flagship performance with low power consumption.

Qualcomm S7 Pro is the first audio platform to support Qualcomm Extended Personal Area Network (XPAN) technology and ultra-low power Wi-Fi connectivity, which can extend the audio transmission distance in homes, buildings or campuses and support lossless music quality up to 192kHz.

The Quan Ding Group also launched a TWS headset solution based on the Qualcomm S7 Pro Gen 1 platform at the fastest speed for customers to choose from.

The S7 Pro platform is composed of two ICs, QCC7226 and QCP7321. QCC7226 is the main control to run user applications, Bluetooth protocol, DSP audio data processing, and AI algorithm platform. QCP7321 is a coprocessor that provides WIFI transmission and sends and receives main control data through the SPI interface.
