Manipulating Sound For Scene 11

In scene 11, Emily walks down the drive listening to music. 

I need to put the music in in post-production and make it sound as if it is coming from the headphones. I found a tutorial on Youtube about manipulating sound in Audacity and had my first attempt.

UPDATE (FEBRUARY 2018)

When editing scene 11, I found that I preferred the music from scene 10 continuing into scene 11 as it links scene 10 (in the past) to scene 11 (the more recent past of the narrative). Therefore, I have not used this manipulated sound. However, it was a good skill to learn.
