#1 Noise Cancelling does not work, or is not strong enough.
A correct fit ensures proper noise cancelling & acoustics. Choose an earpiece size that fits snugly, and twist gently as you insert in your ear for a secure seal. Use the Technics Audio Connect app to control external sound and noise cancelling mode.
#2 Can I switch from one Bluetooth device to another?
Once you pair AZ80 earbuds to your devices via Bluetooth you can connect through the devices or in the Technics Audio Connect app.Once paired, the AZ80’s will auto switch between devices when new media starts playing, or when a call comes through
#3 Why does one earbud have better battery life than the other?
The earbud that is removed from the charging case first starts the Bluetooth pairing process with your devices, which may result in slightly shorter battery life.
