Our take on the AudioQuest NightOwl Carbon

Closed-back version of AudioQuest's flagship 'phones

Audioquest's NightOwl Carbon headphones look and feel as luxurious as their open-back siblings, the Nighthawk Carbon headphones. But this closed-back version offers a bit more bass and better sound isolation. The earcups are made of liquefied wood and plant fibers, molded and solidified into the best shape for comfort and sound quality. This special "liquid wood" material glistens nicely in the light, and shares the same lively acoustic properties as real wood.

AudioQuest NightOwl Carbon

Jonathan from St Louis, MO on 6/15/2018

Crutchfield Customer Review (What's this?)

Full disclosure: I bought these without trying any other brands. The runner up I liked was Focal Listens. I picked AQ because I have tons of their cables and I love there stuff, and the price was right. I could not be happier. They sounded great they day I got them, but after break in, they are absolutely fantastic. While not noise-cancelling, on long flights, even with no music playing, I use them for more comfort and relief from ambient noise. I have a big(ger) head size, these are super comfortable. No regrets whatsoever.

Pros: -Fit great -Continue to improve with break in -First-rate packaging and build quality

Cons: Cord is stiff

NightOwl Carbon Closed-Back Bliss.

Crutchfield Customer Review (What's this?)

Exceptional phones. Most comfortable phones I've owned in decades.....that good! DO allow for long break-in time and you will be rewarded.....I plugged them into a Kloss FM radio stereo output and let play for a straight week. Excellent in bass, mid-range and treble.....not too bright like many. Quite smooth and musical. Cable is too short and slightly stiff.....need an Audioquest 10' mini male to female, which is ordered. Worth stressing the comfort simply don't know they're on!

Pros: Extreme Comfort, Quality, Musicality. Voiced correctly. Excellent base, mids, highs.....not too bright.

Cons: Slightly short, stiff cable.

Crutchfield Customer Review (What's this?)

The first time I unboxed these and listened, I have to admit, I was disappointed. There seemed to be a lot of space but the bass and treble authority was very lacking. I was coming from Audio Technica M50x headphones and I was expected a fairly significant upgrade. However, after about 20 hours of run in, these headphones have really opened up. The bass is definitive and the treble is clear and smooth. The biggest observation about these headphones is how large the soundstage seems to be. It's a pretty big accomplishment for a closed back set of headphones. I would highly recommend these.

Fantastic Cans!

Crutchfield Customer Review (What's this?)

I've been looking for a closed back audiophile headphone for awhile now but didn't want to spend over $400. I initially thought about buying Audeze EL8 at their close out price direct from Audeze, but they were sold out. After reading many reviews I was about to pull the trigger on Monoprice Monolith 1060C when I saw these Audioquest Nightowls go on sale. These phones are well built. Very comfortable. They sound great. An excellent, clear, all around balanced sound. No problem with an iPhone 7. Excellent with a Bluesound Node 2. They should sound even better after 150 hours of use. The one negative is they only come with a short four cable which makes it impossible to sit on the couch and plug into your system. I ended up buying a 10 foot Audioquest mini to mini extension cable. The Tower cable which Crutchfield did not carry. It works great, but I wish they would include a longer cable as standard. Glad I bought these. Highly recommended.

Pros: Quality build. Great sound. Comfortable.

Cons: Need a longer cable or extension.

Exceptional value

James from Dublin, OH on 4/22/2018

Crutchfield Customer Review (What's this?)

I found myself looking for a pair of new headphones - was eyeing the NightOwls based on a ton of great reviews. Was prepared to buy them at retail, but then AQ lowered the price. For the original price they would have been good value, but since the price drop, they're EXCEPTIONAL value. Burn in time took about a week, but made a significant difference. They're very comfortable to wear during a dedicated listening session - I can't imagine going out in public with them; not what I'd call "portable". As many note, the cable is pretty thick. I don't care for it much and will most likely upgrade it (AQ has replacements if you email their CS). My pair was missing the 1/4" adapter, but I've contacted AQ and they'll be sending out a replacement.

Pros: Sounds great Comfortable High Value Nice carrying case Multiple ear pads

Cons: Cable is heavy, stiff, and doesn't "lay" very well. Burn-in time Was missing the 1/4" adapter...

Product Research


Overview: Like the Nighthawk, the AudioQuest NightOwl 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. NightOwl 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 NightOwl 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 NightOwl Carbon a distinctive clear and warm sound.

Drive Units: The NightOwl 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.

Closed Design: The NightOwl Carbon is a true closed-back headphone to give you maximum isolation from the outside world. The earcups feature a vent that runs along the perimeter of each dome and exits through a hidden airflow-resistive port to relieve the buildup of air pressure and let the drivers breathe freely.

Audio Cable: The NightOwl Carbon comes with a 51" high-quality audio cable. Using technologies found in AudioQuest's loudspeaker cables, the larger 51" high-end NightOwl 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 features thick Direct-Silver plating over high-purity copper.

Break-in Period: Like other mechanical devices such as loudspeakers and phono cartridges, the NightOwl 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 NightOwl 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 NightOwl Carbon carries a 1-year warranty. An additional year warranty will be added when you register the headphones with the manufacturer.

No i don't think so, because they are too big and the case they come in is like a mini brief case. Nice headphones and actually thought about ?. I just the the Mrspeakers Aeon Flow closed, which sound better and are lighter and come with a nice little protective case. I just bought them the other day, so far so good. [ JORDAN B  Mar 12, 2018 ]
