Bass Frequency Response on Headphones

What it is: Frequency Response from 20Hz-250Hz
When it matters: When the material is heavy on bass frequencies, such as those of kick drums and bass guitar.
Score components:

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.

Our tests

Low-Frequency Extension

What it is: The lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: Shows how extended the bass is.
Good value: <40Hz
Noticeable difference: 5Hz

Bass Std. Err.

What it is: The amount of deviation (weighted standard error) in bass frequency response (20Hz-250Hz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) bass performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB

[Coming soon]


What it is: The average amount of over/under-emphasis in frequency response from 20Hz-60Hz.
When it matters: Kick drums and low frequency effects get their 'thump' from this range. Mostly felt than heard.
Good value: +/-3dB
Noticeable difference: 0.1dB

[Coming soon]


What it is: The average amount of over/under-emphasis in frequency response from 60Hz-120Hz.
When it matters: Melodic bass instruments have most of their fundamental frequencies in this range. This is where the 'body' and 'punch' of the bass sits.
Good value: +/-3dB
Noticeable difference: 0.1dB

[Coming soon]


What it is: The average amount of over/under-emphasis in frequency response from 120Hz-250Hz.
When it matters: Most instruments get their warmth and full-ness from this range. When over-emphasized, mixes tend to get muddy and boomy.
Good value: +/-3dB
Noticeable difference: 0.1dB
