What do you care about when picking up a new set of over-earphones ? Some factors like the look and comfort are personal preference. Headphones specifications are a surprisingly complicated business. Today I'm going to explain the headphone frequency response and tell you how to identify the best headset through headphone spec.

Frequency response indicates the range of audio frequencies the headphones can reproduce. It's measured in Hertz, with the lowest number representing the amount of bass, and the highest treble. Most headphones have a frequency response of around 20 to 20,000 Hz, which matches that of human hearing.      

The numbers are not really a good indicator of sound quality, although they can help you choose the right earphones for a particular type of music.   For example, if you want lots of bass, then you should look for headphones that support a low bass frequency.  

Learn to read headphone frequency response graphs


Let's go over understanding the headphone frequency response graphs. Often times reviewers use graphs to illustrate how great or poor it is. You can better understand how well the wireless and wired headphone can perform by understanding how to read the graph. Again, this is not the only indication of how good a headphone is.

 

In theory, the line on a frequency response graph should be relatively flat since the range demonstrates the ability of the headphone to reproduce all frequencies equally. The "natural sounding" headphone is said to be slightly higher in the bass between 40Hz and 500Hz. That's where bass instruments and deep male vocals live, remember?!

If the line on the graph is slightly higher on the left side it means the headphones produce sound with more bass response. If the right side of the graph is higher than the left, that means the wireless headphones have a higher response in the middle, highs, and treble. That headset would be considered bright.

 

Bluetooth headphones  have to compensate for the drivers being so close to the ear in the highs, so the highs are "rolled-off" and illustrated by a gradual sloping flat line from 1kHz to about 8-10dB down to 20kHz. In addition, small spikes at higher frequencies are normal as that is due to reflection cancellations in the folds and ridges in the outer part of the ear. But, sharp peaks and deep valleys over 3,000Hz or so are indications of when the headphone sounds harsh.
