With the four (4)-preset EQ modes, clients could use embedded FLASH parameters to change the gain values for each
band of the center frequency and hence customize the four (4)-preset EQ curves based on the preset center
frequencies and bandwidth. Alternatively, clients could also skip the four (4) preset modes and create a customized
EQ curve by changing the center frequencies, gain values and even the bandwidth factors in embedded FLASH
parameters to make the headphone sound better or meet some frequency requirements. However, in this case, the
product will always use one optimized EQ setting and could not allow users to dynamically change into different
preset modes. Clients could also consider reporting Treble/Bass feature unit by embedded FLASH to Windows UAA
driver to allow end-users to adjust Bass (F1) and Treble (F5) by themselves. Therefore there are three
usage/application scenarios as shown by the summary table below:

**Note: Hardware user control type means end-users could select which EQ mode they are going to use by a hardware
switch/button on the product; software control means they could control the treble/bass gain values by GUI in
Windows OS sound device advanced settings.
