How do I assemble the Tracks Air?

The sound engines have slots in them.

Insert the ends of the PowerTrack™ headband into these slots and slide them up a bit.

Make sure to match the L (left) and R (right) markings on the sound engines with the corresponding L and R on the PowerTrack™ headband.

Settle the sound engines over your ears and adjust to a comfortable position.

For optimum sound, make sure the L and R sound engines are over the corresponding ear.
