Bone Conduction Principle
The BenexBesdi SoneHearing S1 utilizes advanced bone conduction technology. Unlike traditional headphones that transmit sound through the eardrum, bone conduction headphones transmit sound vibrations directly to the inner ear through the bones of the skull (specifically the temporal bone). This bypasses the outer and middle ear, allowing for clear sound perception while keeping the ear canal open. This method is particularly beneficial for individuals with conductive hearing loss and for maintaining environmental awareness.

Design & Comfort
The SoneHearing S1 headset is designed for optimal comfort and durability. It weighs only 29g, making it suitable for prolonged wear without discomfort. The open-ear form factor ensures that your ear canals remain unobstructed, allowing you to stay aware of your surroundings. The headset is constructed from plastic and features an IPX5 water-resistant rating, making it durable for various activities and weather conditions.
