The New version works the same as the old one wit the sliders being how you adjust the settings. you are supposed to move the slider to whatever number you like then push the vol+ to see how loud it is, then you set the slider up one or two more numbers and push the vol+ again to see if it got louder or softer. then if it did get louder you set it up another number and try it again to see if it gets even louder. you do this until you reach the highest loudness that your phone will get to, then you leave the slider at that level. mine goes the whole way to the end where it is at 20. I know this because if I set it to one and push the vol+ is is soft, and when I set it to 20, and push the vol+ it is loudest. I really hope this helps someone. if you have problems please feel free to pm me I will be glad to help anyone. Mark
My settings are
Volume = 20
Bass = 1
Echo = 1
The speaker should be OK if you keep the bass low, if you like more bass lower the volume then, This should keep you from damaging your speaker..
