Default Audio Amplifier Circuit, need help


We are designing a headphone amplifier circuit. The impedance of the headphones and the base voltage they require and furthermore the voltage source. In the wake of looking into I have discovered that the LM386N-4 is a well-known decision. As per a datasheet of LM386N-4 - https://www.icrfq.com/part/2377557-LM386N_4.html I have seen many circuit charts however what we don't comprehend is the means by which to pick the voltage increase required for the enhancer.

I initially believed that, need to know the info sound flag voltage and when I duplicated that by the pick up that would need to give the base voltage required by the headphones, yet it gives the idea that what makes a difference in the present which I don't get.

We would greatly appreciate any help.
