Technics has released to market its EAH-AZ70W noise-cancelling True Wireless headphones ($249). Their design, says the company, is based on Technics’ accumulated knowledge of original acoustic technologies, along with a focus on acoustic design combined with noise-cancelling performance.
The large-diameter 10mm dynamic driver built with the diaphragm composed of graphene-coated PEEK material delivers rich bass along with transparent wide range sound. The Acoustic Control Chamber is designed to control air flow and it optimizes the balance of each frequency by increasing the sound pressure characteristics.
The EAH-AZ70W applies Dual Hybrid Noise Cancelling Technology composed of a couple of combinations: Feedforward Noise Cancelling (FF-NC) and Feedback Noise Cancelling (FB-NC) along with a combination of analog and digital processing, realizing a noise-cancelling effect within 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 analog processing are adapted. Since analog control has a low-latency processing speed, the noise caught inside the ear cup can be cancelled accurately with less residual noise, says Technics.
Other features of the EAH-AZ70W include:
Stable connection – 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 realized by the maximum use of antenna parts. With a proprietary antenna structure design, performance is maximized even in the small product cabinet, the company says. Furthermore, the Left-Right Independent Signaling System helps maintain stable connection with proper sound balance between right and left channels.
Excellent-Quality Call Sound – The EAH-AZ70W applies high-performance MEMS microphones’ built-in labyrinth cabinet structure that can suppress wind noise. Unpleasant noises are reduced and the NC performance and call quality are improved. Further, a beam-forming technology is used that enables the voice to be efficiently delivered while suppressing ambient noise to achieve clear call quality.
Ambient Sound Mode – Tapping the touch sensor switches to a this 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.”
Compact Design – The rounded body fits comfortably in the ears even with long use. Research data compiled on 3D has helped design the angle and length of the sound ports. The EAH-AZ70W is available in black or silver, and its performance is equivalent to an IPX4 splash-proof rating. The same-colored charging cradle partially uses a high-grade aluminum material and features an easy-to-use round shape that fits comfortably in the hand during use.
Long-lasting Battery – 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.
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, Amazon Alexa will also be available to be activated through the headphone’s touch sensor.
Technics Audio Connect App – Various functions are available by installing the free Technics Audio Connect app that enables easy pairing and initial settings onto a smartphone.
