Astell&Kern AKR02 Balanced Armature Earphones

Astell&Kern once again partners with the audio masters at Final Audio Design!Tuned dozens of times by the audio experts at Final Audio Design, the Balanced Armature (BA) driver used in the AKR02 is the same unit found in their BA-SS earphones which gives a deep and rich sound.Balancing Air MovementWith Final Audio Design's proprietary BAM technology, the depth and three-dimensional sense of space of the audio can be conveyed. The principles of Dynamic Drivers, combined with the characteristics of Balanced Armature drivers represents the exquisite technique of the Balancing Air Movement (BAM).What is the Dynamic Driver (DD) unit?Originally developed for recording and playback of music, dynamic driver units consist of the magnet, coil, and diaphragm. Often commonly used in generic earphones, they are easier to tune than Balanced Armature units and can be produced at a lower price point. Using a large diaphragm in low frequency can result in good sound, but the diaphragm must be enlarged as well. The principle operation of the lead Dynamic Driver unit (Lead Wires) is to supply an electrical signal to the coil. When the coil receives power, a magnetic field is induced from the vibration of the plate vibrating back and forth known as the oscillation burrowing principle.What is the Balanced Armature (BA) unit?The principle behind dynamic driver units and BA units are very similar. However, BA unit swere originally developed for use in hearing aids, rather than music playback.
