Audio Technica ATH-MSR7NC, ATHMSR7NCREFB Manual

Introduction

Thank you for purchasing the product.
Before using the product, read through this user manual to ensure that you will use the product correctly. Also, keep this manual handy for easy reference when needed.
The product uses proprietary active noise-cancelling technology to provide a comfortable listening environment in areas with high ambient noise. The product features a miniature microphone in each earpiece that pick up ambient noise (such as traffic, air-handling systems, etc.) and create a sound-cancelling signal to effectively block the noise.

• The noise-cancelling function of the product mainly operates to reduce noise at 300 Hz or lower, which means it has almost no effect on noise that is above this frequency (such as telephone ringtones and voices).
• The noise-cancelling function may have limited effect when used in quiet locations or when used to cancel certain types of noise.

   • In case of charging error, disconnect the product from your device and contact your Audio-Technica dealer.

How to connect

1. Select the cable that you want to use, and connect the connector plug of the cable to the input jack of the headphones.
   • Before using the detachable cables, identify the "Connector plug" and the "Input plug".
2. Minimize the volume of each sound device, then connect the "Input plug" to the headphones terminal.
   • Use included airplane adapter to connect to typical airline audio systems.
3. Move the power/ANC switch on the product to the ON position, and fit the earpads over your ears with the side marked "L" over your left ear and "R" over your right ear, adjusting the headband length by sliding the adjustable slider as shown in the figure.
   * Place the product on your head with the opening part facing upward, so that the product can provide stable noise-cancelling performance.

5. After you have finished using your headphones, be certain to move the power/ANC switch to the OFF position, and detach the 1.2 m (3.9') headphones cable from the headphones and the audio device or smartphone.
   • For noise-cancelling without audio, there is no need to connect the headphones cable.
   • The product features the play-through function to operate as stereo headphones and play music from a portable device even if the product runs out of battery (play-through function).
   • Playback sound can be easily heard outside to ensure the quality performance of the product. On public transport systems or in other public places, keep the volume low so as not to disturb other people.

Using the headphones cable for smartphones

* Some smartphones do not support playback and pause functionality for music/movie files.
* Audio-Technica does not provide support for how to use smartphones.

Cleaning

Get into the habit of regularly cleaning your headphones to ensure that they will last for a long time. Do not use alcohol, paint thinners or other solvents for cleaning purposes.

• Wipe the main unit with a dry cloth to clean the headphones/remote control with microphone.
• Wipe your cables with a dry cloth after use if there is sweat or other dirt present. Using an unclean cable continuously will deteriorate and harden the cable, resulting in product malfunction.
• Wipe your plugs on cables with a dry cloth if dirty. Using the plug without cleaning it can cause sound skipping or distortion.
• To clean the earpads and headband, wipe with a dry cloth. Earpads and headband may fade if sweat or water dries on them. If the earpads and headband get wet, we recommend wiping them with a dry cloth and allowing them to dry in the shade.
• For long-time storage, keep the product in a well-ventilated place free from high temperatures and humidity.
• Earpads will deteriorate over time due to use and storage. Replace when necessary. For information about replacing earpads or other parts, or for information about other serviceable parts, contact your Audio-Technica dealer.

Caution for rechargeable battery
The product is equipped with a rechargeable battery (lithium polymer battery).

• If battery fluid gets into eyes, do not rub them. Rinse thoroughly with clean water such as tap water and consult a doctor immediately.
• If battery fluid leaks, do not touch fluid with bare hands. If fluid remains inside the product, it may cause malfunction. If battery fluid leaks, contact your local Audio-Technica dealer.
  • If fluid gets in your mouth, gargle thoroughly with clean water such as tap water and consult a doctor immediately.
  • If your skin or clothing comes in contact with fluid, immediately wash the affected skin or clothing with water. If you experience skin irritation, consult a doctor.
• Never heat, disassemble or modify the battery, nor dispose of it in a fire.
• Do not attempt to pierce with a nail, hit with a hammer or step on the battery to avoid generation of heat, damage or ignition.
• Do not drop the product or subject it to strong impact to avoid leakage, generation of heat or explosion.
• Do not get the battery wet to avoid generation of heat, explosion or ignition.
• Do not use, leave or store the battery in the following places:
  • Area exposed to direct sunlight or high temperatures and humidity
  • Inside of a car under the blazing sun
  • Near heat sources such as heat registers
• Charge only with the included USB cable to avoid malfunction or fire.
• After using the product, be sure to switch it off. Leakage often occurs due to battery drain that results from a failure to switch off product.
• To protect the built-in rechargeable battery, charge it at least once every half year. If you leave it too long, you will have less rechargeable battery life or the battery may not recharge at all.
• Because this product's design is optimized to provide stable noise-cancelling performance, its structure does not allow for replacement of the built-in rechargeable battery after purchase. The battery may have reached the end of its service life if the usage time becomes shorter even though the battery is fully charged, or if charging is still not complete after more than 4 hours of continuous charging. In this case, contact your local Audio-Technica dealer.
