Known for pairs of headphones with only one Dynamic membrane, Tanchjim shows everyone that it can also make Hybrid headphones with the Kasier pair.

Tanchjim is a brand with strengths in headphone design with only a single Dynamic speaker. There are many famous products from the company such as Tanchjim Origin, Nora, Fola, which only use a single speaker but are still highly appreciated by the community for their final sound quality.

But recently, the company has also had experiments with hybrid headphones, using multiple speaker membranes. One of them is the company's latest product called Tanchjim Kasier - the main character in our article today.

Tanchjim's boxes are still often decorated in a very 'Japanese' way, with the company's iconic character named Asano Tanch.

Right in the box, we were introduced to the speaker system as well as the frequency response of this pair of headphones.

In the box, we have an accessory set including a hard carrying case, and 6 sets of tips divided into 2 types: narrow tubes (increasing bass) and wide tubes (increasing brightness). A pretty good point is that Kasier's new tips are made of liquid silicone, giving them a slightly sticky feel, not lumpy rubber like the previous generation.

Kasier's wire is made of silver-plated copper, with a pure white rubber coating very similar to the wires that come with other headphones from Tanchjim. One point worth mentioning is that the headset only comes with a 4.4mm Balanced plug, and does not have a mechanism to change the head to use with the common 3.5mm standard.

Looking on the positive side, the 4.4mm Balance head offers higher power, reduced noise and is considered a higher quality standard than the 3.5mm. However, many people still use the 3.5mm standard because it is popular and easier to use with many types of dongles and music players - so this will be a minus point in terms of Kasier's versatility.

Kasier is actually not a completely new product, but was developed based on a previous pair of Tanchjim headphones called Kara - so it has design similarities with its predecessor.

The outside is divided into 2 parts, one part is a rounded triangle with the company and product name, the other half is transparent so users can see through it and see the crossover system and Dynamic speaker membrane inside.

If you want to see the whole 'suit' of the headset, it's very simple, you just need to turn to the side made entirely of transparent resin. Kasier owns a system of 5 speaker drivers, including Dynamic DMT5 membranes for the bass range, 2 PURE (Balanced Armature) membranes for the mid range and 2 PURE Hi BA membranes for the high range.

The point worth mentioning here is that all of these speaker membranes were personally developed by Tanchjim, not purchased from a third party. This is something the company has also done for a long time with its pairs of headphones that only have Dynamic membranes.

With a complex speaker system and crossover, Tanchjim Kasier also has a larger size and thicker body than Origin, Nora or Fola. But when compared to the general level of the current market, Kasier is still average. I am a person with a common ear size and still feel comfortable wearing it.

Of course, with this size, it will be difficult for Kasier to use it as a headphone for sleeping. If you want to listen to music, you have to sit up straight!

Overall design, Kasier retains Tanchjim's very own 'DNA' with pure white, a touch of light blue and has transparent elements to see the internal components. To say whether this design is beautiful or not probably still depends on each person's eyes, I personally find it suitable because it has a modern and fresh direction.

A more modern sound from Tanchjim

Through each product released over time, we can see the 'evolution' of Tanchjim. Origin has a bright sound quality, little bass but full of detail and airiness. Nora and Fola then added more bass to make the sound a bit warmer, but still kept the characteristic bright sound.

With Kasier, I witnessed a completely new Tanchjim - with a distinctly more modern, contrasting and powerful sound. Unlike its predecessors, which have gentle, even low-volume bass, Kassier gives a much fuller, more explosive bass. Thanks to that, Kasier was able to 'satisfy' those who listen to the Dance, Pop, and Rock genres significantly more fully than the previous generations of headphones I tried.

Try the song Caffeine Freestyle by 24K.Right, the drums beat down with clear, round physical force, accompanied by the harshness of the sub-bass sound in the background. Up to the mid-bass part, the volume will be gradually reduced so as not to interfere too much with the singer's voice, cutting quite clearly at about 200Hz. With this bass, Kasier gives an overall powerful sound, making an impression much faster than Tanchjim's previous bright sound.

Despite the increased amount of bass, Kasier's highlight - and also the strength of the headphones from Tanchjim - still comes from the way these headphones reproduce the singer's voice. Regardless of whether Dynamic or Balanced Armature membranes are used for this range, Tanchjim still always has a clean, full midrange, balancing the airy and realistic feeling.

In the song Hide and seek by Imogen Heap, this female singer's voice is pushed closer to the listener, but the brightness is adjusted to a moderate level so it feels closer rather than revealing all the details. Male singers like Kendrick Lamar in the song Humble receive a bit of sound from the low frequency ranges, so they have a very strong and masculine thickness and grit.

If we are to evaluate harshly, the singer's voice of headphones like Origin or Fola still has a certain 'unique quality' when expressed transparently and with brightness to stand out from the music background. In contrast, the Kasier offers a full midrange, and is likely to be more versatile with more music genres.

Like the entire sound quality, Kasier's high range (treble) also maintains a balanced tone, 'just loud enough' to be in harmony with the other ranges, without trying to attract attention. The Hi-hats in Take Five performed by The Dave Brubeck Quartet are bright, played in a large space, but do not create a feeling of thorns or excess energy.

A harmony worth appreciating

Tanchjim's recent pairs of headphones like Soda, and now Kasier seem to mark a turning point for this brand. They aim for a more modern sound quality, where all sound ranges are taken into account and there is no longer a 'bias' towards high frequencies like the previous generation. This makes these headphones more versatile, suitable for a wide range of music.

Having said that, it must be said again, maybe longtime fans of Tanchjim see this as a change they don't want to have. The headphones have also lost a bit of their 'personality' in the way the singer's voice is expressed that previous pairs of headphones like Origin, Force or Fola brought.
