Elacin Hearing Protection A sound experience

Unmatched universal earplug thanks to CoreHelix™ technology

Also available for: de_DEfr_FRnl_NL

The Elacin Universal ST24 is a one-size-fits all universal earplug intended for incidental use in noisy environments.

Thanks to a unique and innovative design, this hearing protector offers comfortable protection against excessive noise.

The design features two very soft lamellae. At the same time the curvature of the protector matches the shape of the auditory canal of the widest number of people possible in a universal-fit hearing protector offering minimal pressure. The Elacin Universal ST24 has an acoustical filter based on our CoreHelix™ technology. With an innovative internal structure, this technology provides the highest attenuation of any soft hearing protector. This filter provides flat attenuation and allows air to pass through to the auditory canal. The shape of the grip ensures a great seal between the earplug and the ear, because it intuitively encourages you to hold and insert the earplug correctly.
