Author/Source: Frequency response is how well headphones reproduce different sound frequencies. Total harmonic distortion measures how much the sound is changed by the headphones. Isolation is how well headphones block outside noise. Soundstage is the perceived width and depth of the sound. Dynamic range is the difference between the loudest and quietest sounds a headphone can produce. See the full link here

Analogy/Comparison
Testing headphones is like taking a car for a test drive; you’re checking to see how well it performs in different situations.
Why It Matters
Knowing how headphones are tested helps you understand reviews better and choose headphones that fit your needs. For example, if you work in a noisy office, isolation testing will be important for you.
