The special sleep filter guarantees that all ambient noises are attenuated, while ensuring that loud and high noises such as the doorbell or children calling remain audible. The open ducts in the noise attenuators ensure that no pressure differences occur, so there is no sense of being cut off.
SleepSoft ear plugs are made of a durable, soft, flexible thermoplastic polymer. In response to the natural warmth of the ear, the thermoplastic polymer adapts to the shape of the auditory duct within just a few minutes, making SleepSoft plugs comfortable enough to wear all night.
SleepSoft can be easily cleaned with soap and water, and under normal conditions, one set will last 1 or 2 years as long as the plugs are thoroughly cleaned and dried before storage after each use.
