Feature Request: Selectable Gain Levels for Headphone Output (Mini-i Pro 3)

[Zest]

Hi,

For the Mini-i Pro 3, is it possible to add different gain levels for the headphone output like low gain, medium gain, high gain?

I can hear a pretty loud hissing noise on high-sensitivity IEMs.

Please kindly consider. It would make the Mini-i Pro 3 perfect!
