【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
[Equipped with NUARL's unique single full-range dynamic driver] Equipped with the newly developed "NUARL DRIVER [N8]G2" which combines a φ8mm Gen2 graphene diaphragm with a lightweight CCAW (copper clad aluminum wire) voice coil. It produces crisp, powerful sound with high resolution.
[Dual Chamber Driver Modules] Like the higher-end model Overture, it uses a dual chamber structure that closes off the back of the driver and has two independent air chambers. It reproduces the volume of the low range regardless of the size of the housing or driver. The front chamber side of the housing is made of resin, the rear chamber side is made of zinc alloy, and the Sound Tube is made of aluminum to disperse the resonance points of the housing and prevent unnecessary resonance inherent to the materials.
[Patented technology HDSS by T.B.I., USA] A 3rd generation ETL acoustic module is installed on the rear chamber side. It prevents distortion at high volumes and absorbs incidental sounds, reproducing clear and natural sound spread across the entire range.
[Compatible with attaching and detaching Sound Tube] Adopts the Interchangeable Nozzle specification, which is the latest common standard for NUARL wired earphones. By attaching and detaching it, you can easily clean and maintain it, and you can also use the ``Overture'' Sound Tube. The cable uses 0.05mm x 30 twisted 4-core silver-plated copper wires selected exclusively for the Sound:A series. It also supports re-cabling via MMCX connection.
[Two models available for each tuning] Two models with different Sound Tube tunings are available for the global market and the Japanese market. Both support high frequency playback up to 40kHz and are Hi-Res certified.
Sound:A is a standard model created as a series of NUARL earphones that is named after the sound "A" used for tuning musical instruments. Adopting the same interchangeable nozzle structure as the higher-end model Overture, we have prepared two sound variations with different tones for the global market and the Japanese market.
