Swivl marker contains a microphone that picks up the audio. If the audio quality is poor, please make sure that the marker is worn properly. Watch the video below to explore our recommendations for the crystal clear audio:

1. Thread the loop of string at the end of the lanyard through the hole on the corner of the marker (closest to the 3.5 mm jack).

2. Once the loop is fully threaded through, pass the neck or wrist strap through the center of the loop.

3. Pull on the strap to tighten the loop and secure the lanyard to the marker.
