inspired by a legend

"I have thoroughly enjoyed a wonderful partnership with Harman over the past five years, and I am very excited to add the AKG N90Q to my signature line of headphones.” said Quincy Jones. “There are only 12 notes, and no matter what genre of music you are enjoying, whether it be Jazz, R&B, Pop, Rock or Classical, I believe the enhanced experience provided by the AKG N90Q will offer the listener such exact sound and customization that you will believe you are in a professional recording studio.”

Fine tuning


Just rotate the control rings on the ear cup to subtly and continuously adjust the bass and treble level, without distorting sound reproduction. This allows you to fully control the sound regardless of the type of music. This feature was inspired by Quincy Jones and developed under his supervision.

Stage Control


Standard, Studio or Surround? Whether you prefer neutral sound imaging, or you like the feeling of being in a recording studio, the N90Q can be fine-tuned to your personal tastes.


In this setting, DSP spatial processing is disabled. The setting allows the use of external 3D sound imaging like DTS Headphone:X™ or Dolby® headphone


The setting is designed to give you a more natural listening experience, as the producer intended, even though they used monitor speakers, not headphones to produce the content.


This setting adds distance to the sound imaging, creating a more spacious sound, especially suitable for naturally recorded music (orchestra, jazz), and also most pop recordings.


Ensuring extremely accurate sound reproduction

TruNote technology consists of a new, proprietary software solution for auto-calibration and frequency response measurement. In combination with a patented dual foam ear cushion and a pistonic motion driver, TruNote allows music reproduction to reach the maximum sound accuracy.

The auto-calibration solution uses two microphones in each ear cup to measure the frequency response while you are wearing the headphone, and generates an accurate correction filter, all within a second.By analyzing sound pressure distribution, the technology inside the N90Q is able to adjust the sound according to the shape of your ear, minimizing distortion and delivering truly accurate sound.

The patented dual-density memory foam ear cups help to suppress unwanted reflections between ear and driver, but also support passive noise canceling performance while improving comfort dramatically.

Together with the novel pistonic-motion 52 mm transducer that uses a special Japanese paper membrane (positioned off center to allow for maximum alignment between and driver and ear canal), it ensures optimal sound reproduction.

Active Noise Cancelling

The AKG N90Q also includes the world’s first truly audiophile grade, fully discrete analog active noise cancellation circuitry that achieves 20dB wide band noise reduction, without introducing excessive noise on its own. Not only is the external noise attenuated by 20dB (a factor of ten), but so is the distortion arising from the headphone transducer and ear cushion as well. This results in exceptional bass performance and transparency throughout the whole spectrum due to the absence of intermodulation effects.

Only the best, for the best

Crafted with premium materials for extraordinary comfort and luxury. An understated combination of aluminum and leather, the N90Q is a jewel of craftsmanship. Every detail of the N90Q has been conceived and produced with thorough accuracy using premium materials.
