Flagship balanced armature in-ears take IEMs to another level of performance.

No longer available. Please consider final audio design FI-BA-SS, which these earphones are based on.


Custom Balanced Armature Driver with Balancing Air Movement (BAM) Technology, maintains superb clarity at high frequencies and overcomes the deficiencies in low frequencies normally found in traditional BA units (described below in detail).

Detachable Oxygen-free Copper cable (99.99% purity) and connectors to produce a super clean and coherent sound.

Lovely Italian leather case lined with Chamude fabric and embossed serial number.

Each AKR02 IEM unit is hand assembled individually by a skilled engineer in Japan, with the use of a microscope, to achieve the quality and performance expected at this level of audio perfection.

Technical description:

Tuned dozens of times by the audio experts at Final Audio Design (specialist IEM manufacturers), the Balanced Armature (BA) driver used in the AKR02 is the same unit found in their BA-SS earphones which gives a deep, clean, musically neutral; and richly detailed and layered sound quality. How do they do that?

With Final Audio Design’s proprietary BAM (Balanced Air Movement) technology, the depth and three-dimensional sense of space around the music can be conveyed. The principles of Dynamic Drivers, combined with the characteristics of Balanced Armature drivers are the techniques employed in the Balancing Air Movement (BAM) design.

There are many multi-driver Balanced Armature earphones on the market, but almost all suffer from crossover distortion and large size/weight issues. The AKR02 design resolves the crossover and size issues with its own patented technology, the ‘Balanced Air Movement (BAM)’.

The AKR02's driver units are fixed in a unique stainless steel housing, maintaining clear high frequencies and overcoming the deficiencies of low frequencies normally found in traditional Balanced Armature (BA) units.

Typical BA units are generally mounted against the ear, sealing the unit and preventing airflow. The AKR02 design integrates airflow to the BA driver unit. This critical air hole in the stainless steel housing unit adjusts the internal airflow to the BA unit, which maximizes rich bass tones and overcomes the weakness of low frequency response found in typical BA driver units, offering superbly clean and clear audio performance from a in-ear small unit.

The reasonably sturdy cable is manufactured from super pure copper and is detachable from the in-ears, allowing user replacement if necessary and the whole set comes packed in a lovely leather carty case, making them not only a musical joy, but a desirable high quality purchase to be proud of.
