True wireless headphones have been established as a market standard, and in recent years the demand for high-quality sound has been increasing. In order to satisfy this demand, Technics will be releasing the EAH-AZ70W True Wireless Headphones with a thorough focus on an acoustic design that is equipped with the industry-leading noise cancelling performance. The EAH-AZ70W pursues ideal sound by accumulated knowledge of Technics’ original acoustic technologies until now.
10-mm Diameter Driver Unit and Original Acoustic Design
The large diameter 10-mm dynamic driver built with the diaphragm composed of graphene-coated PEEK material delivers rich bass sound and transparent wide range sound. The Acoustic Control Chamber is precisely designed to control air flow and it optimizes the balance of each frequency by increasing the sound pressure characteristics. An energetic rich sound is generated
Dual Hybrid Noise Cancelling Technology
The EAH-AZ70W is applied Dual Hybrid Noise Cancelling Technology composed of a couple of combinations. Firstly, Feedforward Noise Cancelling (FF-NC) and Feedback Noise Cancelling (FB-NC). Secondly, a combination of Analogue and Digital Processing. It can realise an Industry-leading Noise Cancelling Effect in the True Wireless category. For FF-NC that cancels the noise captured outside of the headphones, High-order Noise Filters are adapted and they reproduce signals opposing various noise patterns to cancel noise effectively.
For FB-NC that cancels the noise captured inside the headphone ear cup, Noise Filters controlled by analogue processing are adapted. Since analogue control has a low latency processing speed, the noise caught inside the ear cup can be cancelled accurately with less residual noise. Dual Hybrid Noise Cancelling thus offers perfect circumstances for you to fully engage yourself in your music.
Conventional-type true wireless headphones often cause brief interruptions of Bluetooth connection when in a crowded place. The new models are not only compact but also offer extremely reliable Bluetooth connectivity to ensure uninterrupted listening. The small size was achieved with an integration of a Bluetooth antenna and a touch sensor inside the control section, while improved connection stability was realised by the maximum use of antenna parts. With our own proprietary design of antenna structure, antenna performance is maximized even in a small product cabinet. Furthermore, the Left-Right Independent Signalling System helps maintain stable connection with proper sound balance between right and left channels. The EAH-AZ70W lets users enjoy immersive content viewing experiences in any situations.
Excellent Quality Call Sound
The EAH-AZ70W applies high-performance MEMS microphones built-in unique labyrinth cabinet structure that can suppress wind noise. Unpleasant noises are reduced and the NC performance and call quality are improved. Furthermore, using a beam forming technology that enables the voice to be efficiently delivered while suppressing ambient noise to achieve clear call quality.
Ambient Sound Mode
Simply tapping the touch sensor switches to a mode (Ambient Sound mode) to capture external sounds while listening to music. By tapping the sensor for two seconds, the user can switch between “Noise Cancelling”, “Ambient Sound” and “OFF.”
The rounded body fits comfortably in the ears even for long use. A massive amount of 3D ear data has helped design the angle and length of the sound ports. The EAH-AZ70W is available in black or silver, and features a splash-proof performance*2 equivalent to IPX4*2. The same-coloured charging cradle partially uses a high-grade aluminium material and features an easy-to-use round shape that fits comfortably in the hand during use.
When fully charged, the battery provides six hours of continuous playback (when the noise cancellation is turned ON). In addition, the charging cradle can be fully charged twice and is compatible with up to 18 hours of playback. The user can enjoy using it without worrying about the remaining battery capacity even over long periods of time.
Voice Assistant Compatible (Siri®/ Google Assistant™/ Alexa)
Voice Assistant Compatible (Siri®/ Google Assistant™/ Alexa) Voice assistant smartphone functions such as Siri and Google Assistant can be activated by operating the headphone’s touch sensor. Amazon Alexa can also be activated for users with the Alexa mobile app. Later this spring*3, Amazon Alexa will also be available to be activated through the headphone’s touch sensor.
Technics Audio Connect App*4
Various functions are available by installing the “Technics Audio Connect (free)” app that enables easy pairing and initial settings onto a smartphone.
