Troubleshooting - Technics earphones - Panasonic earphones - audio, sound, noise cancelling, noise problems

Large white noise or unfamiliar, irritating noises are heard.

If "Noise Cancelling" is turned ON, the Noise Cancelling circuit generates some amount of white noise to maximize the noise cancelling effect when used in a noisy environment. If "Noise Cancelling" is turned ON in a quiet environment, white noise may be heard. If the white noise is bothersome in a quiet environment, turn off "Noise Cancelling".

If the white noise level is different between the right and the left earbud, use the troubleshooting below to determine the cause.

A particlurly loud noise that sounds unlike the white noise from "Noise Cancelling" could indicate possible product failure. Please contact the relevant support channels (Technics or Panasonic) to arrange further analysis(or repair).

Use this step by step troubleshooting guide to determine why you are receiving white noise.

No Sound

No Sound from one earphone.

• Make sure that the earphones and the Bluetooth® device are connected correctly.
• Check if music is playing on the Bluetooth® device.
• Make sure that the earphones are turned on and the volume is not set too low.
• Pair and connect the Bluetooth® device and the earphones again. Refer to "Connecting to a Bluetooth".
• Check if the Bluetooth® compatible device supports “A2DP” profile. Refer to the operating manual for the Bluetooth® compatible device.
  If the Bluetooth® compatible device supports the "A2DP" and "AVRCP" Bluetooth® profiles, music can be played back with remote control operations on the unit.
  A2DP (Advanced Audio Distribution Profile) : Transmits audio to the unit.
  AVRCP (Audio/Video Remote Control Profile) : Allows remote control of the device using the unit.

Noise Cancelling does not work effectively for over 600Hz.

Active Noise Cancelling is effective for a low frequency range. For a mid/high frequency range, the Active Noise Cancelling function's effectiveness is less than the low frequency range but mid/high frequency noise can be cancelled by passive noise cancelling effect(sealing effect by fitting earbuds).

Noise cancelling performance is tuned and adjusted within the industry standard

Noise Cancelling does not work or is not strong enough

This answer is for the following models EAH-AZ40, EAH-AZ60, EAH-AZ60M2, EAH-AZ80, EAH-AZ70W, RZ-S500W

• Fit the earbuds correctly and snug into your ear in order to get adequate noise cancelling effect and acoustics. Select and fit the special earpieces that suit the sizes of your ears, left and right.
  
  Image varies by model (Model Shown EAH-AZ80), refer to Operating Instructions for how to fit earbuds correctly for your model.
• Change control of external sounds and select "Noise cancelling" by Touch and holding the Touch sensor "R" for about 2 seconds, you can switch between noise cancelling, ambient sound and off. Selected mode is announced.
• For Technics model EAH-AZ40, EAH-AZ60, EAH-AZ60M2, EAH-AZ70, EAH-AZ80 you can optimize the Noise Cancelling function by operating the "Optimizing noise cancellation" in the Technics Audio Connect app. Tap the "Optimizing noise cancellation" menu at "Settings" in the Technics Audio Connect app and adjust it.
  
  • Adjust a position with the least noise. If you do not nnotice any change, move to a noisier location or rplace earpieces to a size that fits better.
• Noise cancelling does not work during a phone call.

Note:

Noise cancelling is mainly effective during flights, train rides, etc. (low frequency noise). Noise cancelling does not completely remove the surrounding noises.

Left Earphone has faint noise with Noise cancelling on.

Noise will be heard when there is complete silence (audio is not playing). When you are listening to the music you will not be able to hear this noise.

If you experience noise, Update the firmware.

Noise Cancelling is weak or does not work

1. Confirm that the Noise Cancelling function is ON Touch and hold the right earphone sensor unit you hear the voice guidance. If it does not say “Noise Canceling”, release the touch sensor and touch and hold again until the voice guidance says, “Noise Canceling”.
2. Optimize the noise cancelling to your desired level using the app. Open the “Technics Audio Connect” app. Tap “Settings” Under Operations/sound select “Optimizing noise cancellation (pre-adjustment)” Adjust to the point where the Noise Cancellation is most effective to you.

Using the Noise Cancelling or the Ambient Sound function, the sound quality changes a lot

You may feel that the sound quality has changed when you change between sound modes. With Noise Cancelling on, the lower frequency range is lowered to reduce external noise. The earbuds try to adjust sound quality to the best possible sound quality while performing the noise cancelling function.

When using JustMyVoice™ my voice is hard to hear.

• The MIC in the earphones detects your voice and once your voice is detected it reduces the surrounding noise for a clear call. Confirm that earbuds are properly inserted into your ears and are fitting properly.
  
  
  For Model EAH-AZ80 the mic should be face down and "Technics" logo as well diagonally. For EAH-AZ60M2 the "Technics" logo should be horizontal as per the image above.

When using the Noise Cancelling or the Ambient Sound function, effectiveness to one earbud is stronger than the other earbud.

Effectiveness to each earbud is carefully adjusted during production. If you still feel strange, please contact customer service for further analysis.

White noise heard (faint hissing noise), even when Noise Cancelling is turned on.

This answer is for the following models EAH-AZ60, EAH-AZ60M2, EAH-AZ80, EAH-AZ70W, RZ-S500W

The Noise Cancelling circuit generates some amount of white noise to maximize the Noise Cancelling effect. This is normal.

Wind can be heard, even though noise cancelling is ON

Noise cancelling is effective when there is constant surrounding noise but not effective enough to random noise (ex. wind). Our earbud is designed to minimize wind noise, but in some cases it depends on the actual environment or wind type. It may not be possible to completely filter-out wind noise.
