Technics Energetic Sound Technology

Graphic of AZ70’s driver

The large diameter 10-mm dynamic driver
These truly wireless headphones use a wide ⌀10mm dynamic driver, creating a broad soundstage. This makes it easy to generate bass, creating a wide sound field and space perception that sounds like it's coming from much larger speakers.

Graphene coated PEEK diaphragm
In addition to strong PEEK material, the earphones are treated with graphene coating to increase their strength and reduce components vibrating unnecessarily in the diaphragm itself (large internal loss is acceptable). The smooth, clear treble gives vocals an elegant sound.

Acoustic Control Chamber
The Acoustic Control Chamber has been positioned on the back end of the driver, which was adopted with the stereo inside phone EAH-TZ700. It precisely controls the airflow to the front and back of the diaphragm and brings out the driver's original performance mainly in the mid-low range.

Dual Hybrid Noise Cancelling Technology

The EAH-AZ70W wireless headphones use Dual Hybrid Noise Cancelling Technology which is composed of several systems. Firstly, Feedforward Noise Cancelling (FF-NC) and Feedback Noise Cancelling (FB-NC). Secondly, a combination of Analogue and Digital Processing. The combination of these two systems accomplishes an Industry-leading Noise Cancelling Effect in the True Wireless category.

Left-Right Independent Signalling System
