Qualcomm is known for many things aside from their Snapdragon series of chips, and only after announcing the Snapdragon 732G a few days ago, Qualcomm is bringing a new technology called Adaptive Noise Cancellation for true-wireless earbuds that are being made by so many companies in the market. According to Qualcomm, the purpose of Adaptive Noise Cancellation is to serve as the latest technology that is designed to ensure that the user experience is improved.

As the name suggests, the Adaptive Noise Cancellation is designed to adjust the sound performance in real-time, and it is based on how the earphones are going to fit in the user's ears. Which, in theory, means that if the fit changes even slightly, then the Adaptive Noise Cancellation will adapt to make sure that the performance is optimal.
