How to use

Connect the headphones to the dedicated headphone output of your audio interface, mixer or headphone amplifier. Position the ear cups to fully enclose the ears and adjust the headband for a snug but comfortable fit to ensure consistent isolation and accurate monitoring. For critical listening, allow a brief warm-up period for the drivers after powering your audio source. When switching between mono and stereo signals, verify channel routing on your source device to avoid channel imbalance during playback.

Usage recommendations

For accurate mixing, use the PreSonus HD9 in a neutral listening environment and compare mixes on multiple playback systems.
