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.

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.

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.

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.

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.

There are two color variations – CC (ion plating processing) and CG (gold metal plating)

Steel carry case, Silicon ear pieces (E type 5 sizes, A and B types 3 sizes each)

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.

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.
