Our take on the AudioQuest Nighthawk Carbon

Out of their carrying case, the sleek, smooth AudioQuest Nighthawk Carbon headphones really glisten in the light. Their earcups are made of liquefied wood and plant fibers, molded and solidified into the best shape for comfort and sound quality, then polished. They really are a sight to see. Plus they feel solid and have the same acoustic properties as real wood.

Strong first impression

Out of their carrying case, the sleek, smooth AudioQuest Nighthawk Carbon headphones really glisten in the light. Their earcups are made of liquefied wood and plant fibers, molded and solidified into the best shape for comfort and sound quality, then polished. They really are a sight to see. Plus they feel solid and have the same acoustic properties as real wood.

Luxurious feel and effortless comfort

These are large heaphones made for serious music listening. The earcups, metal construction, and leather headband give them a sturdy, robust feel.

But on my head, these heavy-duty 'phones felt like featherweights. AudioQuest uses a patent-pending suspension system that evenly distributes their weight and positions the extra-plush leather earpads at just the right place. During long listening sessions, you don't find yourself constantly fussing around and readjusting the headphones. It's one and done. 

Wide-open sound with plenty of detail

These headphones sound nice out of the box, but really reward repeat listens. After they broke-in, they seemed more powerful and precise, with a nice spread of instruments. 

AudioQuest uses large 50mm high-excursion drivers and a split-gap motor design to optimize imaging, emulating the soundstaging of free-standing loudspeakers. They create a surprisingly wide "virtual soundstage" with substantial bass.

Complex grille created by 3D printing

AudioQuest's outward-facing, open mesh grille controls the flow of air for clean, pure sound. Patterned after the structure of butterfly wings, the complex crisscrossing of metal keeps airflow balanced, cutting down on music-killing resonance. Since it would be nearly impossible to manufacture the detailed part through traditional means, AudioQuest produces it through the modern process of 3D printing.

Product Research


Overview: The AudioQuest Nighthawk Carbon state-of-the-art over-ear headphones are designed with technology found in many of today's loudspeakers. These technologies have been applied to headphone listening, resulting in an immersive and emotional listening experience. NightHawk Carbon headphones come with two pairs of ear pads, a 51" straight cable, a 3.5mm-to-1/4" adapter, two cleaning cloths, and a luxuriously-padded zippered storage case.

Ear Cups: The ear cups are shaped to follow the general contour of the human ear--rounder at the rear, wide at the top, narrowing toward the bottom. This design provides greater comfort and less stress on the listener's head and ears. It also helps isolate external sounds. The headband self-adjusts when you put them on, providing ultimate comfort for long listening sessions.

Ear Pads: Two sets of ear pads are included in the box. One pair of ear pads is made of Protein Leather, a bio-derived synthetic fabric that is durable, pliable, and soft. Protein Leather ear pads seal tighter for better isolation and improved treble clarity. The other set features an Ultra Suede covering which breathes freer for greater comfort and enhanced bass impact.

Liquid Wood Enclosures: The NightHawk Carbon's ear cup enclosures are made from all-natural Liquid Wood. Liquid Wood is made of 100% renewable raw materials, including lignin, natural fibers, resins, and waxes, combined and treated so that it can be injection-molded. The enclosures have support beams that give them structural integrity, much like the internal bracing in a loudspeaker cabinet. Liquid Wood has far superior acoustic properties than plastic or other materials used in headphones, which gives the NightHawk Carbon a distinctive clear and warm sound.

Drive Units: The NightHawk Carbon utilizes 50mm dynamic drivers that resemble the high quality drive units found in the most sophisticated loudspeakers. The diaphragms are constructed of rigid bio-cellulose with a urethane rubber surround, which results in well-controlled bass, rich midrange, and natural highs, with low distortion.

Semi-open Design: Unlike the NightOwl Carbon, the NightHawk Carbon has an open back design to give you a three-dimensional soundstage. The open area is covered by a 3D-printed grille that promotes the diffusion of sound, while preventing sound waves from reflecting back toward the driver, creating standing waves and distortion.

Audio Cable: The NightHawk Carbon comes with a 51" high-quality audio cable. Using technologies found in AudioQuest's loudspeaker cables, the larger 51" high-end NightHawk cable uses high-purity copper conductors with very little oxygen content. The cable's plugs feature Direct-Silver plating over a base metal of Tellurium Copper (TeCu). TeCu is known for it's purity and machinability, which results in better plating quality and contact mating for improved signal transmission. The cable has a 1-button remote on the yoke with controls for music playback and phone calls. The supplied 3.5mm-to-1/4" adapter that also features thick Direct-Silver plating over high-purity copper.

Break-in Period: Like other mechanical devices such as loudspeakers and phono cartridges, the NightHawk Carbon headphones require a "break-in" period in order to reach optimum performance. A suggested break-in period is approximately 150 hours listening to music at safe volumes. A similar "burn-in" period for the NightHawk Carbon cable is also recommended. This can be accomplished by leaving your components powered on, and the headphones plugged in, even when there is no music playing. This allows the molecules in the dielectric to gradually be arranged from a random order into a more uniform order. This process can take approximately 2 weeks.

Warranty: The AudioQuest NightHawk Carbon carries a 1-year warranty. An additional year warranty will be added when you register the headphones with the manufacturer.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

Already have a pair of these phenomenal headphones. When the price dropped, I spoke with Rusty and eventually decided to order another pair for primary use with my stage piano. Thank you, Crutchfield, and all your excellent advisors! You've become my source for all things audio/video! [ Dolores  Sep 06, 2018 ]
Couldn't pass on the price [ Paul  Apr 14, 2018 ]
From the expert advice of your customer service staff. Specially, both Dexter and Peyton. THANK YOU! [ Lauren  Feb 23, 2018 ]
I was looking for a comfortable headphone that gives just enough detail to appreciate the music, rather than so much that your listening experience suffers as a result. I also wanted a relatively balanced tuning, without overly bright highs. As I spoke with Dexter via chat, he provided links to multiple headphones that I didn't know existed, despite having felt as though I'd done some research. Thank you Crutchfield and many thanks to Dexter for his patience and experience! [ Lauren  Feb 22, 2018 ]
