WPG Group launches active noise reduction Bluetooth headset solution based on Qualcomm technology

On April 21, 2021, WPG Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its subsidiary Quan Ding launched the Adaptive aptX+ANC active noise reduction Bluetooth headset solution based on Qualcomm QCC3044 AIT development board.

According to Qualcomm's latest consumer audio research report, more than one-third of respondents rely on their audio devices to help them relax, exercise, work, and stay connected with loved ones during the global pandemic. And 43% of respondents already own or are planning to buy true wireless headphones. And 71% of consumers surveyed said they are very interested in wireless headphones with high-quality sound.

Qualcomm's new generation of stereo headsets and earbuds SoC platforms and QCC3044 Bluetooth SoC combine strong connectivity, ultra-long standby time, excellent sound quality (Adaptive aptX), voice assistants and integrated ANC with features designed to enhance the true wireless hearing experience.
