Troubleshooting

Up to 10 Bluetooth® devices can be paired with the earphones. If you pair a device when the maximum number of paired Bluetooth® devices is exceeded, previously paired devices will be overwritten. To use overwritten devices again, pair them again.

Unpair this unit from the Bluetooth® menu in the Bluetooth® device, and pair again.

Check if the earphones and the Bluetooth® device are connected.

Check if music is playing on the Bluetooth® device.

Check if the earphones are on and if the volume is not too low.

Pair/connect the earphones and the Bluetooth® device again.

Check if the Bluetooth® device supports the “A2DP” profile. For details, please refer to the manual of the Bluetooth® device.

Are you covering the earphones or Bluetooth® device with your palm? The signals and audio may be interrupted.

Are you out of the Bluetooth® communication range (about 10 m)? Bring the earphones and the Bluetooth® device closer together.

Are there any obstacles between the earphones and the Bluetooth® device? Avoid obstacles.

Turn off wireless LAN devices that you are not using.

Using devices that interfere with radio waves, such as microwaves, may affect communication.

Depending on the signal conditions, radio waves in the same 2.4 GHz band as Bluetooth® may interfere and cause sound skipping.

When using LDAC and multi-point together, change the “LDAC playback sound quality setting” and “connection setting” of the playback device from “prioritize sound quality” to “best effort” or “prioritize connectivity” to lower the bit rate. You may not be able to change the settings on some playback devices. For details, please refer to the manual of the playback device.

Setting [Suppression of sound interruptions and delays] to [Suppress the interruption of the sound] in the [Technics Audio Connect] app may resolve the problem.

Check if the Bluetooth® device supports the “HSP” or “HFP” profile. For details, please refer to the manual of the Bluetooth® phone.

Check that the audio settings of the Bluetooth® phone are set to communicate with this unit.

EAH-AZ80/EAH-AZ60M2: If JustMyVoice is on, the earphones detect your voice with a speech detection microphone so that the other party can hear you. Your voice cannot be detected if the earpieces are not in close contact with your ears. Replace with earpieces that fit well in your ears.

EAH-AZ80/EAH-AZ60M2: At default settings, JustMyVoice is on. When talking in a quiet environment, turning off JustMyVoice may resolve the problem. You can turn it off even if [We recommend enabling the setting.] is displayed in the setting screen.

To make calls using an app on a computer connected through Wi-Fi®, we recommend setting the Wi-Fi router to the 5 GHz band, which does not interfere with Bluetooth® radio waves.

Wear the earphones correctly.

The volume of Bluetooth® devices such as smartphones and the volume of the earphones may be controlled separately. Increase the volume of both the earphones and the Bluetooth® device.

Is there earwax or dust in the earpieces? Foreign matter such as earwax or dust may clog the protective mesh of the earphones and decrease the volume or change the acoustic characteristics, resulting in malfunction. If the sponge inside the earpieces get dirty, remove the earpieces from the earphones and clean them.

The left and right may vary depending on signal and operating conditions.

Using the microphone of an earphone for calls will quickly deplete the battery of that earphone.

The remaining earphone charge values may differ between the left and right on the [Technics Audio Connect] app.

Confirm that the voice assistant is set to Amazon Alexa.

Confirm that your mobile device can transmit data.

Confirm that the device is registered in the Amazon Alexa app.

If the charging cradle status indicator LED turns off immediately when you try to charge, the charging cradle is fully charged. If the earphone status indicator LED turns off when you put the earphones in the charging cradle and open the lid, the earphones are fully charged.

If the charging and operating time have gotten shorter, the internal batteries of the earphones and charging cradle may be exhausted. (Each internal battery can be recharged about 500 times.)

Immediately after purchase or when this has not been used for a while, the charging cradle status indicator LED may not turn on for a few minutes after starting to charge, but will if you continue charging. If it does not turn on even after a while, please request your dealer for repair.

Is there any foreign matter or dirt on either ends of the USB charging cord and on the contacts of the connected devices?

Firmly connect one end of the USB charging cord to a computer or separately sold USB PD supported AC adapter (USB Type-C connector), and the other end to the charging terminal of the charging cradle.

If you are using a computer USB port, confirm that the computer supplying power is on. It will not charge if the computer is in standby or sleep mode. (If it still does not charge, try another USB port on your computer.)

If this unit does not charge even after trying the measures above, remove the USB charging cord and insert it again.

Is the charging cradle placed properly on the wireless charger?

Charge at a room temperature between 10 °C to 35 °C. Higher room temperatures may result in longer charging times. Depending on your wireless charger, charging may be slower or may stop.

Are the charging terminals of the earphones dirty?

Are the earphones properly inserted into the charging cradle?

If you are using third-party earpieces, you may not be able to charge them with the included charging cradle. Use the included earpieces.

Although the earphones or charging cradle may get warm while charging, it is not a malfunction.

EAH-AZ80/EAH-AZ60M2: If the charging cradle is not placed properly during wireless charging, the wireless charger, earphones, and charging cradle may get hot. For correct placement, please refer to the manual of the wireless charger.

Turn them off and then on again. (Put them in the charging cradle, wait about 15 seconds, and then take them out.)

Are the touch sensors disabled?

At default settings, the music pauses and the touch sensors are disabled when you take off the earphones.

When putting the earphones down on a desk, etc., the earphones may be detected as being worn or music may be played if the wear sensors are close to the desk. To prevent erroneous operation, take care to keep the wear sensors away from the desk, etc. when putting the earphones down.

The wear sensors may not work if they are dirty or moist. Wipe off any dirt and moisture with a dry, soft cloth.

The battery has no charge. Charge with the included USB charging cord.

It could not charge properly. Remove the USB charging cord and insert it again. If the problem persists, clean the charging terminals of the earphones and the charging cradle terminal section.

If the charging terminals of the charging cradle become abnormally hot, immediately unplug the USB charging cord and contact your dealer.

The temperature of the charging cradle internal battery is abnormal. Stop charging and wait for a while. We recommend charging at an ambient temperature between 10 °C to 35 °C.

The earphones are not properly inserted into the charging cradle. Put in the earphones again properly.

Is there dust, water droplets, or dirt on the terminals of the earphones or charging cradle? Remove dust, water, and dirt.

The pattern differs depending on whether the charging cradle lid is open or closed. (This is not a malfunction.)

Wear the earphones correctly.

Replace the earpieces.

EAH-AZ80/EAH-AZ60M2: Select the best earpieces.
