As always, her voice gives peace to one's heart, and this plot helps to bring out the kindness of her sound. I don't think anyone interested in this product will have any questions about her voice.
As for the plot, however, I think it is an interesting choice, and my feeling is undetermined. On one hand, the sound from a variety of ear-cleaning tools is, well, interesting, but because it is in the ear tunnel, the sound gets closely similar to each other. On the other hand, it kinda distracts me from her talking because I was trying to understand the difference.
These are just my thoughts, please don't get too serious, your experience should not be biased by others' opinions.
