Without noise reduction earbuds, users (especially teenagers) will crank up the volume (reaching 120dB) to compensate for the background noise levels (for more than one hour) which is way too high.
The acceptable levels is around 90-95dB. This is very bad for your ears as the increased volume hitting your eardrums can lead to internal ear problems. One such problem is tinnitus. This is a medical term used to describe ringing noises in the ear when there is no such noise outside the body.
By wearing noise reduction earbuds, you can enjoy your music at a much lower level, thus protecting your ears from damages. As well, by lowering the volume, you will extend the battery life.
