PS:

"Thanks for the useful post. I have one suggestion, though: I think it
might be better to use 1K resistors rather than 10K. The input impedance
of a typical amp should be in the region of 20K. At audio frequencies
(where impedance-matching doesn't matter) it is best if the input
impedance is at least x10 the output impedance. Assuming an output
impedance in the range 100-600 ohms (plausible for an MP3 player
headphone output), that would keep the total output impedance below 2K
which should result in more signal voltage across the amp's input." -
