Op Amps! What are these little things? An operational amplifier, or op amp for short, is a tiny electronic component that's like a supercharged mini amplifier. It takes in electrical signals from one or more sources, boosts them up, and then sends them out as bigger signals. It's commonly used in all sorts of electronic devices, like audio equipment, sensors, and even in everyday gadgets like smartphones. Basically, it makes electrical signals stronger and more useful for doing things in circuits.
And this is great for headphones! Usually the output of a digital to analog converter is too weak for headphones to use, so amplification is needed. And in comes the opamp. But not every op amp is the same, especially when you listen to audio.
