Make sure the audio source is not delayed. Please note that every additional audio device (mixing console, amplifier, etc.) may increase the latency.

Mobile devices, especially Android phones, can add a higher latency (also see the "List of tested mobile devices").

Wireless headphones may have a higher latency than wired headphones, which do not add any latency.

Make sure the audio source is not distorted or noisy.

Make sure the input sensitivity and gain settings of the audio source as well as the gain settings of the ConnectStation are adjusted correctly.
