Interesting Facts About Portable DACs
A DAC converts digital audio data into the analogue signal used by wired headphones. External DACs can bypass the basic audio hardware built into a phone or computer, potentially providing lower noise, stronger output and more consistent sound depending on the connected device and headphones.
