How do I stop the whistling?
The whistling sound is normal and can be fixed by ensuring a snug fit or changing your ear dome size. Frist turn the noise to a minimum or turn it off. Then re-choose the appropriate size of the earplug to wear, to ensure that the earplug and the ear canal close contact. Gradually adjust the volume from small to large to find the best volume for you. And make sure not to block the pickup and speakers.
