JustMyVoice
The six MEMS mics of the AZ40 headphones use Technics’ JustMyVoice technology to isolate and amplify your words and minimize wind noise. The result are crystal clear hands-free phone calls.
Sound Modes
The integrated microphones also work with different sound modes that you can engage based on your situation. Activate Natural Ambient Mode to capture both voices and surrounding sounds, letting them in so you’re fully aware of your surroundings. Attention Mode focuses only on people’s voices, letting them in so you can clearly have a conversation or listen to an announcement.
Voice Assistant
Simply touch the side of the earphone to engage your preferred mobile device’s digital assistant. Alexa support is built into the AZ40 headphones, but you can also select Siri.
Multipoint Pairing
Pair with two devices at the same time and seamlessly switch between them with Multipoint technology. Play a game on your smartphone, watch a video on a tablet, then switch back to take a call. All without re-pairing to each device.
Charging Case
On a full charge, the earphones can provide up to 7.5 hours of playback, with an additional 17.5 hours stored inside the included charging case. If you’re in a rush, a quick 15-minute charge in the case will give you up to 90 minutes of playback.
Outdoor Friendly
With an IPX4 rating, the AZ40 true wireless headphones can withstand a splash or getting caught in the rain.
Technics Audio Connect App
Made for iOS and Android devices, this app gives you convenient access to certain aspects of the earphones. Control the EQ, view the battery life of each earphone, adjust sound modes, and more.
