CCA - NRA

CCA NRA has been engineered from the ground up to deliver superior performance in terms of sound reproduction. The way they can achieve this is by employing cutting edge low voltage electrostatic technology in the NRA. Designed to house a 6.8mm speaker utilising electret technology, this delivers consistent and stable sound. The engineering behind this technology is that whenever there is a change between two electrode plates due to an electrical signal that creates electrostatic and allows the electrostatic driver to phonate and produce sound. The low voltage electrostatic technology makes it easy to drive the earphone with just 25 Ohms of impedance, allowing it to perform with even a cellphone. Utilising this technology, the NRA can deliver better sound density and clarity while reducing distortion levels to a minimum.

The CCA NRA features a unique configuration and combination of driver setup. NRA encases 1 electrostatic driver and 1 dynamic driver that deliver professional-grade sound. The magnetic force of the dynamic drivers is 3 times stronger than a standard dynamic driver and this allows for balanced sound distribution in the low, mid and high range of the frequency spectrum. The electrostatic driver ensures much more stable transmission and delivers outstanding reproduction in the 20kHz range. The combination of the electrostatic and dynamic driver allows the NRA to accurately reproduce sounds from 20Hz to 40kHz, allowing you to enjoy your music with Hi-Res clarity.

The CCA NRA earphones feature high-quality materials and expert level craftsmanship. Zinc alloy material is used to design the metallic housing making it durable and sturdy. The housing showcases complex craftsmanship giving it a futuristic look. Medical grade resin is utilised to design the casing of the NRA, allowing for a snug fit, effectively isolating external noise by 26dB. The cavity is designed to fit the ear canal perfectly and has been designed ergonomically for a comfortable and stable wearing experience. The overall design reflects the extraordinary quality and feels like a premium product.

The cable included with the CCA NRA is high-quality and delivers a distortion-free audio signal. A double line silver-plated cable comes bundled with the NRA, and this cable enhances Hi-Res performance and reduces loss of audio during transmission. This new type of double line parallel cable has lower impedance and features an anti-tangle design. This prevents winding of the cable and reduces damage caused by pulling the cable making it durable and offering a longer usage life. These cables feature a 2Pin connector on one end and a 3.5mm connector on the other, allowing for easy connectivity with various devices and even allowing for upgradability. The connector plugs are gold plated reducing distortion and allowing for cleaner audio transmission.

The included cable with the CCA NRA features a high-quality microphone for receiving calls and communication. This microphone is a condenser mic capable of transmitting high definition audio. There are quick-access functions assigned to the button in the microphone housing and it allows for receiving calls, rejecting calls, playing/pausing music and changing the songs played. This is truly useful as you don’t need to access your devices to execute these used functions.
