Sandisk Clip Sport audiobook problem

[jk98]

I got 4 out of 6 right, however that was in a quiet room, at relatively high volume, and not really listening to the music, but concentrating just on the high frequencies for any clues of compression. On a portable player, at low volumes, and with portable headphones, especially in a noisy environment using open earphones, I would likely do very poorly on the test.
