The Standard wired earphones

Sound:A is a standard model created as a series of NUARL earphone sound standards, named after the "A" sound used in tuning musical instruments. It features the same interchangeable nozzle structure as the high-end Overture model, and is available in two sound variations with different tuning for the global market and for the Japanese market.

Equipped with NUARL's unique single full-range dynamic driver

The newly developed "NUARL DRIVER [N8]G2" combines a φ8mm Gen2 graphene diaphragm with a lightweight CCAW (copper-clad aluminum wire) voice coil. It delivers high-resolution, crisp, and powerful sound.

Like the high-end Overture model, it features a dual-chamber structure with the driver's rear sealed off and two independent air chambers. This design reproduces rich low-frequency sound regardless of the size of the housing or driver.

Composite Hybrid Material Housing

The front chamber of the housing is made of resin, the rear chamber is made of zinc alloy, and the sound tube is made of aluminum. This design disperses the resonance points of the housing, preventing unwanted sounds specific to each material.

The third-generation ETL acoustic module is installed in the rear chamber. It prevents distortion at high volumes, absorbs incidental sounds, and reproduces clear, three-dimensional, and natural sound across the entire frequency range.

The cable is crafted with specially selected 0.05mm x 30 strands of twisted 4-core silver-plated copper wire, tailored for optimal performance with the Sound:A series. Additionally, it facilitates re-cabling through an MMCX connection.

Compatible with removable sound tubes

It features the Interchangeable Nozzle, a common specification in the latest NUARL wired earphones. This allows for easy cleaning and maintenance, and also enables the use of the Overture's Sound Tube.

Faq

What is the difference between the "Global version" and the "Japan version"?

The sound quality (bass feeling) differs due to the different sound tuning of the Sound Tube. There are no other differences in performance or specifications.

Can I purchase the "Global version" or the "Japan version" in my country?

The availability varies depending on the distributor in each country. Please contact a distributor in your country to check if you can purchase it.

How do I wear the earphones in my ears?

Insert the earpiece into your ear canal and hang the cable over your ear from front to back for a stable fit.

Can I use the Sound Tube from Overture?

Yes, the Sound Tube for Sound:A is an Interchangeable Nozzle specification of the same standard as Overture.

Can the earphone cable be shared with Overture?

The earphone connector for Sound:A is MMCX, so it cannot be shared (connected) with the Overture, which uses the Pentaconn Ear specification.

Can I use other earpieces?

You can use NUARL earpieces such as BlockEar+7, MagicEar+9, and TrackEar+. However, please note that we do not confirm the compatibility of third-party earpieces.

Can I use commercially available detachable earphone cables?

Generally, earphone cables with MMCX connectors can be used. However, please be aware that we do not confirm the compatibility of third-party products.
