Headphone Review: Dunu Trident

We were first introduced to Dunu when I reviewed their Hephaes IEM which proved to have great quality. However, I have been one to recommend the Tridents over the Hephaes, but never gave them a formal review. For being such a great, affordable IEM, the Trident has unique design qualities while still maintaining that high quality sound that we still want in any headphone making it one of the best bang for the bucks out there.  Read on for the full review: 


  • Driver Type: Dynamic
  • Frequency Response: 10 Hz – 20 kHz
  • Impedance: 16 ohms
  • Sensitivity: 100 dB +/- 2%

In the Box

  • Dunu Trident
  • 6 Pairs of Silicone tips (2 Styles in S/M/L)
  • Leather Carrying Pouch

The Dunu Tridents don’t come with much, but that’s what you expect from 40 dollar IEMs.


What can I really say about these IEMs, they have a unique shape to them. Being called the trident is not on accident either, they literally look like the points to a trident, now if humans had three ears, it would be perfect. As always, Dunu goes out to choose some of the best materials that are not only strong and tough, they also look great. The rigid looks of the Tridents glow, glisten, and gleam in any light near them making them really pop in anyone’s eyes. The outer edge of the IEMs house the Dunu logo while circling around them is either a blue or red band to mark the left and right sides respectfully. Dunu is one of the companies that pay great attention to design, the Tridents are no different.

The Tridents offer a really unique design that will be sure to attract any wandering eyes.

Design: ★★★★★


The main sound of the Tridents is fairly balanced with a really slight V to them stressing the higher mids though. The bass is punchy and warm while the high end takes from its design and offers plenty of details and sparkles beautifully as you get up into the higher-highs, but the lack of presence in the lower-highs can seem somewhat problematic.


The bass’ focus here is definitely on the mid-bass as this punch is really what you feel and hear. Texture is extremely powerful and strikes a complete and detailed picture of the bass in your head; it’s quite magnificent really. The mid-bass needs no body as it creates its own presence just fine, but is still delicate enough to never dare enter the mids or highs. The bass has beautiful punch and texture to it while still maintaining a really powerful body to create the presence it needs to score itself a five here.

Bass: ★★★★★


The midrange is definitely still a strong suite of these IEMs. By focusing more on the higher mid-range, the Tridents create really beautiful energy and dynamics in the vocals. Clarity is definitely there, but there is a slight loss of detail in the lower mids in some heavier songs. Instrumental energy also does lack compared to the vocals. With good detailing of specific instruments, the Tridents score high in terms of timbre. Although the sound stage is slightly smaller though, separation is still grand.

Mids: ★★★★


The high end on the tridents are vivid and can be lively. The lower-highs however, do suffer in terms of gleam and glare as they don’t sparkle or extend the way I want them to. Although they do have some sparkle, Dunu didn’t take it the extra mile. As you extend up higher, the sparkle is more apparent, detailed, and lively. Clarity is really beautiful on the tridents while the detailing and separation can use some work. Overall, Dunu did do a great job on the high end here keeping quality in mind, there are a few things to work on, but nothing bad.

Highs: ★★★★

Noise Isolation

The Dunu Tridents are well above average in terms of noise isolation; they may not be earplugs, but are close enough. I can definitely recommend using these for isolation.

Audio: ★★★★½


The pouch that these come with not only looks classy, but will keep your IEMs looking classy as well.

Like the Hephaes, the Tridents keep a strong composure when it comes to build quality. Although it doesn’t come with 2 cases like the Hephaes, or three in terms of the Ares, the single included leather pouch not only screams quality, it also protects the headphones well. The metallic housings on the Tridents will be able to take quite a few attacks and still live on without a scratch. They don’t only look and feel nice, they have the strong aspect to them as well.

The cable that these come with is just really strong.

The cabling used on the Tridents is strong and flexible with a good thickness. All three of these improving build quality. However, what really sets these apart is the included cable management system built right into the cable. This system works wonders and should really be included with every pair of IEMs. The headphone jack on this model is straight and composed of strong plastics and metals. Current models use the same angled jack from the other Dunu models which is better for build overall.

I’ve said it once and I’ll say it again, the cable management system that come with these should be built into every IEM.

Build: ★★★★★


The tridents may look funny, but it still works wonders in terms of comfort. After inserting these, they just disappear and go away entirely. Although it’s made of metal, the IEMs still stay fairly lightweight to add on to the actual comfort. Six pairs of tips are included to ensure a proper fit and comfort.

To ensure proper fit for sound and comfort, Dunu includes six pairs of tips in two styles.

Comfort: ★★★★★


I have dubbed these IEMs as the best pair of in-ears anyone can purchase under 50 dollars, They remain there today and will be really hard to dethrone on those terms. For under 50 dollars, I really can’t see myself telling you to go any other direction unless you want Classical, then in that case, grab yourself a pair of EtyKids. The Tridents offer amazing audio quality able to battle with headphones more than twice its price of around 40 dollars. They are available through various third party retailers like Amazon and eBay.

Value: ★★★★★

Final Thoughts

Although Dunu’s Hephaes provide slightly better quality in the mid-range with bass that is more explosive and fun than the Tridents, the Tridents still remain my favorite IEM from them by far. Boasting a really low price tag, these IEMs blast out sound that can play with the big boys. If you’re in the mood for a new sound, definitely give these a second glance, you’ll want to anyways due to their popping design.

I’d like to thank Rocky for the review sample.
