Headphone Review: Nocs NS600 Crush

Nocs | In-Ear Monitor | 149.95

Nocs, the Swedish company goes on further endeavors, but this time, reaching back into a driver they’ve used before. This time, however, they double the stakes. Dual drivers, a tweeter and woofer, are enclosed in a sand blasted aluminum housing. The design remains beautiful, and true to Nocs. 


  • Driver: 5.78 mm Tweeter + 8.00 mm Woofer
  • Frequency Response: 20 Hz – 20 kHz
  • Impedance: 20 ohms
  • Sensitivity: 110 dB

The NS600 Crush comes with a nice quantity of accessories


Sandblasted in silver, the Nocs NS600 Crush is coupled with a beautiful, natural texture to them. Reminiscent of a matted type design, while still having a slight shimmer to it, the Crush does have a unique design taking advantage of the aluminum housing. The Nocs name is camouflaged on either side of the housing in silver. The housings are really quite beautiful.

The Crush has a gorgeous design.

Design: ★★★★★


Just about every manufacturer tends to be trending towards dual drivers, while many can easily cram 2 armatures into a housing, Nocs decides to go with dynamics. The result is a V-shaped signature with a textured, boomy low end, sweet mids, and shimmering highs.


The low end focuses mainly on a the mid bass. The result is that the punches come out with a stronger thump that is well defined. Impacts remain strong and consistent with great presence. This does, however, take a bit away from the deeper sub-bass overshadowing some of the texturing. Otherwise, the texturing has a nice fluidity to it while still remaining the body that the Crush naturally has.

Bass: ★★★★½


The midrange remains ample with the lower detail. They are more subtle and less in your face, but can use a little better retrieval. Vocals have a nice lushness to them while maintaining sweetness. This results in in good vocal dynamics for the NS600. Subtleness is really what the mids seem to be about with the Crush, as the clarity is definitely there, but again, not upfront and screaming at you. The midrange has a laid-back, relaxed feel to it, but doesn’t end up reducing any of the quality properties and remains as musical as needed.

Mids: ★★★★½


As we step up into the high end, we do find that it becomes the main weakness of the NS600. Lower highs have a nice presence to them with a quicker decay. The higher highs really tend to steal the show though. They have a strong, yet soft, sparkle to them that really holds the energy for the Crush’s treble. Detailing is superb up here, but separation really needs some work. Smearing tends to be a recurring issuing with these. Sibilance can also be found here and there.

Highs: ★★★★

Audio: ★★★★½


As with the NS800, the 600s come with the same Nocs branded case. The case itself is thin and portable with a sense of fashion behind it. It sits right between the hard case and the soft pouch. The case does a nice job keeping the soft aluminum from damage while they are not in use.

Nocs includes the same case they use for theNS800.

That said, the NS600 has a nice housing on it. The Aluminum feels very light, and doesn’t seem like it’s a thick layer, but also not thin. The housings serve as a gateway of design and comfort. I feel the protective properties of the housings are ample to protect the drivers though. The strain relief that comes out of each housing is long enough with a nice flexibility to them.

The cable that comes equipped with the NS600 are very thin. Nocs utilizes TPU to encase the cable that also has Kevlar reinforcement. The cable does have a nice firmness to it throughout, although the cable on the lower half is thicker than that on the upper.

The cable looks absolutely gorgeous.

The cable terminates at the headphone jack, the same headphone jack that is used on the 800s are used on the NS600s. The jack itself is very strong, and holds a sense of durability. The strain relief is flexible and not too loose. I would still rather have an angled jack though as they tend to last a lot longer.

The headphone jack is straight.

Build: ★★★★½


The choice of aluminum for the housings was more likely than not entirely to keep the IEMs light. This light weight helps a lot with the comfort of the IEM and allows them to be used for hours on end without even knowing they are there. The sharp edge can irritate a bit while inserting the NS600 though. Nocs includes 2 sets of each sized tip (1 for spare, because we tend to lose some after a while) to ensure a good fit and seal.

Users have 3 tips to choose from, that should be enough for an adequate seal.

Comfort: ★★★★½


The NS600 Crush will bring you back around 150 dollars. This is a competitive price point for what these IEMs offer. They are worth the price, no doubt, but there are a few caveats to still hurdle over. They don’t offer the highest bang for the buck in this price range, but do very well for the audio quality you get. Comfort is great, build is good. Nocs also includes a 3-button remote and mic for iDevice users.

A remote and mic comes in handy when on the go.

Value: ★★★★½

Final Thoughts

The NS600 Crush is a change of pace from the almost neutral NS800. In a way, it’s a nice change. The signature is upbeat, but not too overdone. I have to say that Nocs did a good job on their first dual-dynamic headset. The lightweight design and materials used offer a minimalistic IEM with strong sonic capabilities.

I’d like to thank Nocs for the product sample
