Typically used in professional broadcasting, the original aptX™ audio codec is widely used for 16-bit near-CD quality sound. The benefits of the aptX™ codec include superior compression, low computational cost, and low transmission delay.

An unbalanced connection typically consists of a signal (L + R) and the ground. The ground is supposed to prevent external noise, but noise can still be introduced to the signal and can affect transmitted signals that causes variations and noise in sound. The balanced connection was developed to reduce ground noise as the signal is transmitted
