In certain smartphone/headset combinations the audio and haptic sensations may be out of sync. This is due to different formats and codecs.

In such cases we recommend pairing Strap to your audio source and using a wired connection from the Strap to the headset.

Alternatively, a solution which may address this problem is a BT splitter which transmits two BT signals simultaneously. An example of this is shown in the link below:
