Comfort and Clarity for Long-Haul Mix Sessions
HD9: Professional Monitoring Headphones

Hear for yourself.
Mix for everyone.
When you need to do serious work without bothering anyone in your living space and without being distracted by outside sound, choose PreSonus® HD9 headphones. They're clean-sounding, extra-comfortable, and offer a broad, transparent frequency response that ensures accurate mixing.

Nothing but clear, accurate sound.
The HD9’s closed-back acoustic design provides superior listening isolation and reduces headphone bleed, so you hear nothing but music—and your housemates hear nothing at all.

Peerless construction, surgical accuracy.
The HD9's 45 mm dynamic, neodymium drivers and high power handling (900 mW per channel into 40 ohms) deliver loud, clear, clean audio, minimizing listening fatigue. Best of all, its tailored frequency response extends all the way from 10 Hz to 26 kHz, with accurate bass response, enabling precise mixes.

Comfort matters.
The lightweight HD9 features an adjustable headband, cups that rotate 180° on two axes, and comfortable, durable ear pads. The straight, ten-foot cable drops down one side so it doesn’t get in your way. The result is a comfortable listening experience that you’ll continue to enjoy during long sessions. And the HD9 is built tough so you can rely on it wherever your travels take you.

You listen thoughtfully—so why not think like a listener?
The PreSonus HD9s are an invaluable addition to your sonic toolbox. While there will always be a place in the studio for powerful and articulate studio monitors, fact is that more people are choosing portable, personal listening solutions nowadays. As trends in listening shift, it’s wise for you to check your mixes on high-quality headphones as well as on your finely calibrated studio monitors. With the HD9s, you can rest assured that your mixes are translating well across myriad listening environments.

And with the HD9’s combination of comfort, adjustability, sturdy construction, and acoustic isolation, you can mix better for longer.

Now hear this!

Are you and your session players and bandmates tired of straining to hear underpowered headphones? We were too, so we created the HP4 headphone-distribution system. These headphone amps are louder than you’re ever likely to need for session and stage use, so be careful with that level control! Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to hear!
Simple and versatile.

Simplicity is the HP4’s hallmark. You get left and right line inputs, left and right line outputs with level control, and the four headphone outs. You can globally mute the headphone outs and sum the stereo signals to mono, adjust the individual headphone levels, and mute the rear-panel Monitor outputs while leaving the headphone outputs active. So while the HP4 is simple to set up and use, it has all the features you need to create a versatile headphone system.
Compact and expandable.

The compact HP4 can sit on a tabletop or can be screw-mounted to a standard rack tray (not included), where it requires just 1/3 rackspace. And if your needs grow, you can use the line outputs to feed the inputs of a second HP4 or the larger HP60 headphone amplifier. So quit struggling with mediocre headphone amps. Get the HP4 and hear everything loud and clear. You owe it to your music.
