Check to see if eartips are placed properly in the ear canal?
The eartips should pointed slightly away from your body or try using them in the other direction. Is the fit better?
Do the metal binaurals feel twisted in your ears?
Hold both the binaurals/eartips in your hands, pointed away from your body, gently push them away from you to align, using equal pressure. Is the fit better?
When you tap on the diaphragm, does it make a drum sound?
If not, your diaphragm is loose. Tighten by holding head and turning Retaining Ring clockwise.
Are the diaphragm and retaining ring still attached to the head of your scope?
If not, contact us for replacement parts.
Are you in a noisy environment?
Place entire palm over headpiece and apply the correct pressure using the palm of your hand.
Is pressure too light, allowing ambient noise to come in under the head?
Tap on the diaphragm lightly with your fingers, can you hear a drum like sound? If not, your diaphragm may be loose. Hold the head and turn the retaining ring clockwise to tighten it.
