Why NUGUNA Safety Earphones?

Listening to your favorite music in exactly that right volume is something we all love. However, using earphones isolates you from the environment.

The louder the volume the less aware you are of important sounds around you.

Unfortunately, we can’t control the volume of critical sounds in our environment. We can’t increase the volume of a car honking while we walk or bike down the street. We also can’t increase the volume of alarms in the office, in public buildings or even, sometimes, at home.

NUGUNA earphones are wireless earphones that detect sounds and alert the wearer towards the direction of sounds in their surroundings with vibrations.

NUGUNA earphones take on the sound- detecting, safety feature of the ears leaving you able to safely enjoy your favorite music.
