Pre-Amplifier for stereo condenser microphones

Hello community,

I would like to run Binaural Microphones/Earphones with a raspberry pi:


These are stereo condenser microphones built into earphones. The mics need to be amplified by 2V to 10V.

How would you do this? Is there a HifiBerry product, where you have 2 outputs und 2 inputs, where you can somehow attach a 9v battery? Is this maybe a product idea?

Many greetings and thanks,
