Tired after a day with many impulses? Lack of concentration? Sensitive to sound? You may very well be highly sensitive or sensitive to overstimulation. vcepmakes special earplugs for this purpose with the unique PF filter that dampens mainly high frequencies and thus removes ‘the sharp edge’ of the ambient noise. These filters are available in four different levels and are interchangeable. This means that the earplugs can always be adjusted to your personal situation.
