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.

Please check the L (left) and R (right) indicators on the left and right bushes. 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 find this position, it will easy to replicate it on subsequent occasions.

* It is usual that a person’s ears differ from left to right in terms of shape. As such, the optimum positioning of the product differs from left to right.
