4-Channel Headphone Amplifier with 4 Closed-Back Headphones

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.
