• The plugs ensure effective pressure equalization when adapting to different altitudes: the small hole at the plug entrance only allows a tiny amount of air to pass through, and the second small hole at the other end of the plug slows down the incoming and outgoing air flow.
• The pressure difference between the outer and inner ear is reduced and therefore also the resulting pain.
• The BLOX airplane also acts as a hearing filter. Unpleasant, loud and disturbing noises are reduced to an acceptable level.
• Important sounds (speech, ambient signals, radio and TV) remain audible.
