What is it indicated for?

The Bio-logic Ear Muffins® is a disposable earphone device intended to be used as an accessory to the Bio-logic ABaer / Navigator Pro auditory evoked response screening and diagnostic systems, and the Natus Medical Inc. ALGO series auditory evoked response screening systems. The Ear Muffins® device performs as the means for delivering the auditory stimulus from the auditory stimulator to the ear of the patient under test.

The Bio-logic Ear Muffins® device is especially indicated for use in the auditory evoked response screening of newborn infants, because the Ear Muffins® can be placed to cover the entire ear of the infant, so nothing has to be placed into the ear canal.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
