The EQ earplug consists of a membrane holder and a Sympatex® membrane. The membrane holder is made of hypoallergenic, hydrophobic medical silicone, resistant to chlorine, seawater, and temperatures between -10°C and 60°C. Consisting of a fin and a cup, it is placed behind the first curvature of the ear canal to guarantee the waterproofness of the ear while preserving comfort and long-lasting support in the ear.

The Sympatex® waterproof and breathable membrane allows air to circulate between the eardrum and the plug, which has the benefit of preserving hearing and balance while reducing the risk of infection.

The EQ earplugs are supplied with an ergonomic applicator to facilitate insertion of the plug into the ear and are delivered in a carrying tube that can be attached to a key ring.
