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.
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.
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.
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.
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.
With an IPX4 rating, the AZ40 true wireless headphones can withstand a splash or getting caught in the rain.
