Hybrid Multi-Driver Technology -  A Loudspeaker in an Earphone
Hifi loudspeakers generally have two or more drivers to handle different frequencies. The A8 follows the same principle with the latest hybrid multi-driver system in an acoustic housing just like a loudspeaker, with dedicated Balanced Armature micro drivers for mid-to-high frequencies and a large 10mm Graphene Dynamic driver for low frequencies, thereby taking full advantage of the different properties of the two driver types for optimal performance.

The A8’s 3-driver configuration is the ideal choice for a multi-driver set up because it effectively covers the full frequency spectrum (and beyond) without the side-effect of Phase Distortion caused by delays in crossover networks - a problem that becomes progressively acute in systems with 5 or more drivers.

Precision Dual Balanced Armature Drivers
Balanced Armature (BA) drivers offer incredible sonic accuracy and power efficiency in a tiny size, making them ideal for use in small, high-end monitoring-grade earphones.
​​The A8 features two high precision BA micro drivers made with top quality German components - one covers frequencies from 8kHz to 10kHz, the other from 10kHz all the way up to over 40kHz. The extended frequency range conforms to the stringent requirements for high resolution audio capable of revealing the finest nuance not possible with conventional drivers.

While some critics may point to the fact that the human ear cannot detect sounds at such high frequencies, the extended range does make for a more relaxed listening experience across the whole musical spectrum in the same way a more powerful car would always feel more relaxed at any given speed than a less powerful car.
