WARNING:
Volume up? - No!
When people use headphones, they tend to choose a higher
volume than with loudspeakers. However, if your hearing has
deteriorated and you need to rely on an assitive listening
system, please avoid listening at high volume levels for a long
time. Please protect your hearing.
