At the recent Snapdragon Summit, Qualcomm introduced its latest audio technology – the Qualcomm S7 and S7 Pro Gen 1 Sound platforms. These new chips aim to revolutionize the audio landscape for earbuds, headphones, and speakers, promising enhanced performance, power efficiency, and advanced connectivity.

These platforms bring a robust on-device AI, making them smarter than their predecessors. With six times more computing power and nearly 100 times more AI capacity, they promise better audio without draining your device’s battery.

The S7 Pro Sound platform introduces Qualcomm’s XPAN tech and micro-power Wi-Fi. Essentially, this new tech makes use of low-power Wi-Fi to extend the reach of Bluetooth earbuds, speakers, and headphones. It can detect how well a Bluetooth connection is working and smoothly switch over to Wi-Fi when you go beyond Bluetooth’s range. Qualcomm XPAN also offers high-quality audio at 48 kHz and 96 kHz without losing any quality. They also make sure there’s less delay when you’re watching or listening.

The S7 and S7 Pro Gen 1 Sound platforms make improvements in quick-response noise cancellation, support for multiple audio channels, and energy-efficient operation. For users, this means the best noise cancellation performance yet, especially in noisy places like offices or cafes. The noise cancellation adjusts automatically to stay effective even if the earbud shifts or the surrounding noise changes suddenly.
