Dual Audio Input 70 mm Speaker Headphones

We designed the Aurras to meet the most critical audiophiles taste. The extended bass is playful yet controlled, alive and striving with visceral rumble. The midrange is compelling, with a focus on realism and immersion. Reaching the highest-end, we delivered all the airiness and sparkle of a quality treble experience--without the fatigue. 

The 70 mm Tesla graphene coated dynamic drivers are a tamed beast without any compromise that's capable of producing a vast range of bass frequencies with minimal power requirements.

The graphene material created extremely low-mass drivers. These light weight drivers respond quickly to signals and minimize decay time, resulting in a very realistic music reproduction. Nevertheless, we mechanically decoupled the driver from the housing, which decreased the total harmonic distortion. After that, we added a lightweight graphene layer to the diaphragm to boost rigidity, decrease distortion, and improve speed and decay. Least but not last, our seasoned engineers tuned these drivers for an enveloping full-spectrum experience.

Therefore, you can drive it without an additional amplifier. At 115dB per 1mW power, it may be play from most phones and laptops. The appearance is classic, elegant, and luxurious, like the upholstery of a deluxe vehicle. We made them round-shaped to accommodate a variety of ear shapes and sizes. 

The ear cups are hand-made of all-natural materials that has excellent acoustic properties. The headband is cuddly on the outside, steel on the inside. The result feels plush yet durable. It has a subtle amount of clamp force, but it and the headbands size can be adjusted for comfort. 

We made the grilles as wide as possible to accommodate the large 70 mm dynamic drivers.
