Is there any impact while listening to meditations etc with headphones in the scalar field?

Yes, it will.

Anything you can do to relax the body will improve the body’s response to absorbing and making use of scalar energy.

Besides, better to be relaxed and in a state of tranquility than to be stressed and anxious even when not in a scalar field.
