Why did I get a message about the headphones affecting the result?

January 1, 0001

And what do I do about this?

The output of headphones and earbuds varies and while the “tone” noises used by Sound Scouts are audible with most headphones, on occasion the output of some headphones may impact (reduce) the audible levels thus affecting the results. In these situations no session is used and the supervising adult is advised to retest the child with different headphones/earbuds.
