Replacing the wire.

About aptX Adaptive

Adaptive is a groundbreaking new audio coding technology which combines robust premium audio quality, low-bit rate audio transmission, scalability and the opportunity for low-latency designed to create the ultimate superior wireless listening experience for end users. 

What this means in practice is that the codec is designed to automatically adjust to provide optimum audio quality or latency depending on what content is being played on the device while also taking into account the external RF environment to help robustness. It is engineered to just work, with no synchronization issues for gaming and A/V and multimedia applications.
