Technics Energetic Sound Technology

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.

Highest Level of Hybrid Noise Cancelling in the Industry

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.

Stable Connection even in crowded areas

Unique Touch Sensor Antenna and Proprietary Circuit Design

The AZ70W wireless in-ear headphones offer extremely reliable Bluetooth connectivity to ensure uninterrupted listening. Their small size was achieved through an integration of a Bluetooth antenna and touch sensor inside the control section, while the earphone’s improved connection stability was attained via the optimal use of antenna parts. With our proprietary antenna structure design, antenna performance is maximized even in a small product cabinet.
