This document serves as the owner's manual for the Technics EAH-AZ70W Digital Wireless Stereo Earphones, providing comprehensive instructions for their use, maintenance, and troubleshooting.
The Technics EAH-AZ70W are digital wireless stereo earphones designed for audio playback and phone calls. They connect to Bluetooth®-enabled devices, such as smartphones and tablets, allowing users to listen to music, watch videos, and manage phone calls wirelessly. The earphones feature touch sensors for various operations, including playback control, volume adjustment, call management, and activation of voice assistants. A key feature is the external sound control function, which allows users to switch between noise cancelling, ambient sound, and off modes, optimizing sound quality for each setting. The unit includes a charging cradle that not only stores the earphones but also charges them, providing power on the go. The earphones are equipped with built-in rechargeable lithium-ion batteries.
The earphones are designed for ease of use and comfort. Before initial use, users are guided to properly fit the earphones and select the appropriate earpiece size (XS, S, M, L, XL are supplied, with M size pre-fitted) to ensure adequate noise cancelling and acoustics. The left earphone has a raised dot for easy identification of the L side.
Charging is a straightforward process. The earphones and charging cradle are charged using a supplied USB charging cord connected to a computer. The charging cradle LEDs indicate its charge status, while the earphone LEDs show their charging progress. The charging cradle, when fully charged, can recharge the earphones approximately two times, offering extended usage without a direct power source. Battery level notifications are provided through blinking earphone LEDs (blue to red when low) and a beep sound, as well as through the charging cradle LEDs when the lid is opened.
Turning the earphones on and off is simple: they power on automatically when taken out of the charging cradle and turn off when placed back inside.
Connectivity is established via Bluetooth®. The manual details the pairing process for first-time connections, where the earphone LEDs blink alternately in blue and red, and for subsequent connections with already paired devices. The earphones can be paired with up to 10 Bluetooth® devices. The "Technics Audio Connect" app enhances the user experience by enabling software updates, customization of settings (such as connection mode, auto power off, and guidance language), a "Switch/Find headphones" function, and battery charge checks. The app also facilitates easier Bluetooth® connection.
For music listening, the earphones support A2DP and AVRCP Bluetooth® profiles, allowing remote control of playback from the connected device. During phone calls, the earphones support HSP and HFP profiles, enabling monaural sound reception and two-way communication via the built-in microphone. Users can answer, reject, and end calls using the touch sensors. The volume can be adjusted during calls.
The external sound control function is activated by touching and holding the R-side touch sensor for about 2 seconds, cycling through noise cancelling, ambient sound, and off modes. Noise cancelling reduces external sounds, while ambient sound mode allows users to hear their surroundings through the microphones while still enjoying music.
A unique feature is the ability to use just one earphone independently. For instance, a user can use the R-side earphone for music or calls while the L-side earphone charges. When both earphones are taken out of the cradle, they automatically connect wirelessly for stereo sound.
Voice assistant functions (Amazon Alexa, Siri, etc.) can be activated by touching and holding the L-side touch sensor. Specific setup instructions are provided for Amazon Alexa through the "Technics Audio Connect" app.
Regular maintenance ensures the longevity and performance of the earphones. The unit should be cleaned with a dry and soft cloth. For stubborn dirt, a damp, well-wrung cloth can be used, followed by a dry wipe. Solvents, benzine, thinner, alcohol, kitchen detergent, or chemical wipers should be avoided as they can deform the exterior case or remove the coating. Dust on the charging terminals should be wiped off with a soft, dry cloth, avoiding pointy objects.
To maintain battery performance during long periods of disuse, it is recommended to fully charge the unit once every six months.
The earphones have an IPX4 equivalent water resistance rating, meaning they are protected from splashing water. However, the charging cradle and USB charging cord are not water resistant. Users are cautioned against charging the unit with wet hands or when water droplets are present on the earphones or cradle. Soapy water or immersion in water should be avoided. If water gets on the earphones or microphone, it should be wiped off with a soft, dry cloth, as water droplets can affect sound volume or cause distortion. If water enters the earphones or charging cradle, use should cease, and the dealer should be consulted, as improper handling due to water ingress is not covered by the warranty.
Troubleshooting tips are provided for common issues such as no sound, low volume, disrupted sound, inability to connect to Bluetooth® devices, and phone call problems. These include checking connections, ensuring proper pairing, adjusting volume, and moving closer to the Bluetooth® device. Instructions for restoring the earphones to factory settings are also included, which can resolve persistent pairing issues by deleting all registered device information. This process involves taking out one earphone, touching and holding its touch sensor for specific durations, and then repeating for the other earphone.
