Phonak Serenity Choice SLEEP - Hearing protection with filter
The Phonak Serenity Choice SLEEP hearing protector is designed specifically for sleep. It reduces background noise and ensures quiet nights.
 
The earplugs are reusable and available in three different sizes. Thus, the plugs can be perfectly adapted to any size of ear canal. Thanks to soft lamellae, the earplug sits comfortably in the ear.
This means that there is no irritation in the ear and the most even sound insulation possible is guaranteed across all frequencies. At the same time, the advanced membrane filter technology ensures adequate ventilation of the ear.
 
The ventilation of the ear prevents a "heat build-up" and the associated itching in the ear. In addition, hearing your own pulse or the sound of blood is reduced, which is especially common with side sleepers.
