I listen to Audio books daily in bed before going to sleep.
I was wondering if that will effect my hearing on the long run.
I set the volume to 3 or 4 out of 22 on my creative Zen, so the volume is very low.
I use regular headphones, not earbuds.
Good do not use earbuds because the intensity will be higher compared to headphones.Just make sure you do not turn up the volume too high.1/2 is the max volume , which means 11.To do that you need an ear break too.However, in your case its alright. The Key is Low Volume, Headphones and regular interval breaks.
Hope that Helps.
