After products in the high-end price range, DUNU is back with a pair of Subsurge headphones that bring extremely 'heavy' sound quality to those who listen to EDM, Pop and Rock!

In the second half of 2026, it seems that the headphone market is going in a new direction with products with 2 Dynamic speakers on each side. After the success of Crinear Monolith, Nightfall, then Cozoy D2, now DUNU also joins this game with its latest product called DUNU Subsurge.

Although they have the same configuration, each pair of headphones has a completely different way of optimizing and creating a different sound style. And with Subsurge, DUNU wants the music to be explosive and powerful!

DUNU Subsurge's box has the main black color, with a headphone image and decorated with motifs reminiscent of the galaxy.

DUNU's accessory set is always highly appreciated, even with mid-range earphones like Subsurge. We have up to 4 sets of S&S tips, 3 pairs of Candy tips, 3 pairs of regular rubber, headphone cleaning wire and clothespins for the wire.

Subsurge's wire has a very special color, bright blue (baby blue), from small details such as the 3.5mm plug, wire splitter to the 2-pin head are also made in the same color. This is a quite soft wire, does not create a stiff or uncomfortable feeling in actual use.

Subsurge's faceplate is mainly made from purple mixed with dark blue, with layers of emulsion. Like the box, the 'motif' decorating this pair of headphones seems to be inspired by outer space, stars and galaxies, which actually looks quite nice!

A pretty good point is that the entire body is also made from acrylic plastic with this purple-blue color, rather than turning black like many other pairs of headphones.

This shell is somewhat transparent, so we can see the speaker system inside, including a 10mm Dynamic membrane for the bass range and another 8mm Titanium-coated Dynamic membrane for the mid and high ranges.

There are up to 2 speaker diaphragms on each side but Subsurge still has a small design, as long as you choose the right type of tips, you will wear it comfortably. It is worth mentioning that the tips provided by DUNU are all of good quality (even resold by the company to external users), so we do not need to buy additional tips for good ergonomics.

DUNU also has a few pairs of headphones made of metal, even at a cheaper price range, so we cannot say that Subsurge has superior finishing quality. But overall, the headphones are still sturdy enough, and also have highlights in their design and color.

'Super explosive' sound quality from 2 Dynamic speakers

As mentioned above, although the configuration of 2 Dynamic speakers has become a 'trend' in recent times, each company has a different way of fine-tuning the sound quality. With Subsurge, DUNU puts every indicator into action, by dramatically increasing bass and treble to create extremely powerful V-shape sound.

Subsurge's bass range is quite large, just put it to your ear and listen to the first few songs to clearly realize this. One point worth mentioning about this pair of headphones is that the bass is focused more on the mid-bass rather than the lowest frequencies (sub-bass), seemingly contrary to the current general trend. This causes the drum sounds when pressed down to have a boomy feeling, somewhat overflowing into the background rather than stopping quickly.

Try the song All Falls Down by Alan Walker, the drum beat is very heavy, creating a very clear physical feeling and making a strong impression right from the first beats. For those of you who often listen to gentle Jazz and Ballad music, this will definitely be a bass band with residue, especially with a large distribution in the mid-bass that will also make this band take up a lot of space for the singer's voice.

With V-shape headphones that focus more on vibrancy and strength, the mid-range will not be the thing that gets the most attention. The singer's voice, piano, guitar and violin sounds will be pushed one step deeper by Subsurge, sometimes overpowered by the drums if the song has many complex components.

However, it seems that the company has also tried to refine this strip to have a certain naturalness. The voices of Phuong Ly and the members of the DaLAB group in the song Run From This World are full, warm and just clear enough. Because the position of the midrange part does not go straight to the listener's head, the Subsurge's ability to clearly hear small details is only at an okay level, difficult to compare with bright-sounding headphones like the Juzear Light Shuttle, for example.

Up to the treble range, Subsurge pushes the energy back, thereby creating a V-shape sound with a lot of contrast with the low range. This helps the Hi-hat sounds in Avicii's The Nights stand out above the pounding drum background below, pushing the tempo of the song faster.

Overall, DUNU Subsurge is aimed at those who have a large music library with exciting songs, EDM songs by Avicii, Alan Walker, Calvin Harris or Hip Hop by MCK, Wxrdie, then listening to this pair of headphones will be very enjoyable. On the contrary, 'maximizing' the excitement will also cause this pair of headphones to trade off the ability to express gentle music genres that require more comfort like Norah Jones or Laufey.
