Bass describes the low-end spectrum of frequency response and ranges from 20Hz to 250HZ.
It is the deep and heavy tones in your music, like low rumbles, kick drums and bass instruments. Depending on your listening taste, well-balanced bass is essential for optimal audio reproduction.
For bass performance, we measure the low-bass, mid, and high-bass frequency response, then use these values to test for the standard error of the bass reproduction.
When it matters
Some music genres, such as EDM, hip-hop, rock, dubstep, etc., are arranged to be bass-heavy. Headphones with great bass performance reproduce the bass spectrum of a track as it was arranged.
An over-hyped bass profile will cause the bass in some tracks to overpower the mids and highs, which might not suit everyone's listening taste. Inversely, an under-hyped bass profile will cause bass in some tracks to sound hollow and feel lacking , especially if the tracks didn't have much bass to begin with.
However, personal taste is important when making a selection, as different bass profiles suit different listeners. Also, the importance of bass depends on listening activity. Movies, for example, require more bass than podcasts or audiobooks.
