Heaven VI

The first balanced armature earphones that reproduce
perfectly natural vocals.
We've taken some core concepts of our Heaven IV earphone, tweaked them and applied them to our new balanced armature earphone: the Heaven 6. We've changed the housing from stainless steel to chrome copper and taken our Balanced Air Movement (BAM) mechanism to a greater level of performance. The result is the first balanced armature earphone that perfectly reproduces the sound of a human voice.
BAM mechanism produces bass sounds and stereo spatial interpretations
With balanced armature driver units, iron is driven to produce sound, and as such, these drivers face a number of problems, amongst which are "proving tiring to listen to", "having sound that is subtle and beautiful, but lacking in depth and being flat" and "lacking bass interval". At final, we decided to focus on developing technology for the reproduction of bass tones and three-dimensional space with the full-range reproduction of a theoretically unproblematic single driver unit, rather than taking things in a multiway direction. We went back to the beginning and reviewed the performance of the balanced armature driver, focusing our attention on something we had previously overlooked ? airflow inside the housing. We developed BAM (Balancing Air Movement), a mechanism that optimizes airflow inside the housing through the creation of an aperture in the driver unit, which is usually sealed.

While achieving bass tones and deep, three-dimensional spatial representation, which proved difficult with single driver full-range reproduction, we achieved a BA type that at the same time made for natural listening the user doesn't tire of.

Using BAM, which optimizes airflow in the housing, this driver unit has been developed to our own specifications and has an aperture arranged on the back of the driver unit, which is usually sealed.
Machined with high precision, this has a highly rigid machined chromium copper housing, in line with the evolution of BAM
Together with BAM, which has evolved further from Heaven IV, we created a new design, rethinking everything including how to maintain the BA driver. Machined from chromium copper, the housing necessitated an extremely high level of precision belying its simple external form. At the same time, to use the expensive and difficult to machine chromium copper housing in a product that was reasonably priced necessitated the development and introduction of a new processing method. The machining of hard, tenacious chromium copper was made easier than it was previously. With chromium copper and new BAM, we achieved a more natural sound quality than before. Above all, there is a distinct difference with previous BA types in terms of the naturalness of peoples voices and vocals, the easiest for the human ear to reconcile between good and bad. The lingering tones of vocals as they fade away in a large live music venue are unique to chromium copper. With this model, you can experience a spatial spread like never before.
Original ear pieces available in five sizes
Three types of ear pieces come with the product. The new E type employs two types of silicon differing in hardness for the sound conduit section and the section that comes into contact with the user's ear. Compared to the section that comes into contact with the user's ear, the sound conduit section utilizes a harder silicon with grooves in it, so as to combine strength with flexibility. Can be fitted into the user's ear while maintaining its round shape. For the section that comes into contact with the user's ear, soft silicon has been employed, making for a comfortable fit and a high level of sound insulation. Joining the E type and the five sizes it comes in SS/S/M/L/LL are the A type and the B type, which differ in terms of how airtight they are and in terms of bass reproduction (come in three sizes). Please choose the size and type that is right for you.
An original cable that suppresses touch noise
Compared to previous cables, this is more flexible. An original, flexible cable that suppresses touch noise.
BAM aperture that reduces sound leakage and dispenses with the need for an aperture on the back face.

How to wear the earphones
Please check the L (left) and R (right) indicators at the back of the left and right housings. Holding the product, fit into the ears using a slight twisting motion. Since sound quality differs greatly according to the positioning of the ear piece, move each ear phone around while playing music until you find the position with the balance that suits you best. Once you have experienced this position, it will be easier to find subsequently.

* The L (left) bush has a left and right identification protuberance, so that it is possible to distinguish between left and right in the dark by feel.
* It is usual that a person's ears differ in shape from left to right. As such, the optimum positioning of the product differs from left to right.
Sound quality reviews
Extremely mellow, across all bands, bright sound is characteristic of this product. In particular, middle frequencies have a unique reverberatingtimbre, and the product is well-suited to sound sources such as vocals and pop music. There is no doubt that you will be drawn in by the vividness and beguiling expression of female vocals in particular.
User reviews
When I started collecting earphones, I gave them a trial at a specialty store and I was captivated.
I only knew that Yuzuru Hanyu used these luxury earphones; when you use them, you understand their value. I took my friend, who has no real partiality regarding earphones to an electronics retail store, and when they listened to them, the model that really surprised them was this one.

The subtle, smooth sound from the BA driver is unrivaled. There's nothing close to it; I bought up single BA earphones from other manufacturers, but in the end I couldn't find anything, so I bought these.
And I'm completely satisfied.

This model is my favorite of the Heaven series.
It wouldn't be an exaggeration to say that the mellow female vocals have a beautiful, beguiling sound that nothing surpasses. Low frequencies are also different to the image of a single BA, and have a fullness and an edge that sinks into the music.
I recommend that when you trial these, you listen to music with female vocals and a focus on strings. When I listened to these before, the burr of the high frequencies bothered me. Following the change in the packaging, however, this has been settled with the accompanying E series ear pieces. This product is one that makes you glad you own it the more you use it.
The only flaw I can think of it would be the cable touch noise.

You listen to it once and immediately understand its "enjoyable resonance".
I've tried a number of earphones, and these were a first for me.
Music with female vocals and acoustic sound gives you goosebumps.
They're definitely on point with the comment of "reproduces vocals with perfect naturalness".
With a single BA, the volume of bass tones is consequently on the low side, but listening with Heaven VI, I came to realize that "this is quite satisfactory".
The sound field is by no means wide, but these earphones have a resonance that makes up for this.
