Adjusting the bass attenuation
The more holes you seal with the sealing tape, the greater is the bass attenuation. This increases the speech intelligibility without increasing the 
volume – which is an advantage for people with a 
hearing impairment at high frequencies.
Use the two supplied sealing tapes to seal the small holes in back of the headphone systems of the A 200.
