PreSonus HP4 The loudness of your headphones will vary depending on their design and their input impedance. The output impedance of the HP4 is 51 (ohms), and it will work fine with professional and consumer headphones but the volume will differ depending on which type of headphone you use. Headphones with lower input impedances will generally be louder than higher-impedance headphones. (In this case, louder does not mean better!) Most professional headphones have impedances between 150 and 600. Consumer headphones for CD players and the like often have impedances between 8 and 32. Broadcast headphones are specialized, and you are unlikely to use them with an HP4; their impedances are typically between 1.5 k (kilohms) and 2 k.
