Feature1. 46dB wide-band active noise reduction, which can block 99.5% of background noise and cover the 2KHz noise range. 2. Three noise reduction modes are available: Deep noise reduction: subway stations, airports Balanced noise reduction: street, gym Mild noise reduction: library, office 3. Provides three transparency modes, allowing you to enjoy music without missing important ambient sounds around you, and you can also grasp the wonderful things inside and outside your ears at the same time. 4. Adopt self-developed dual-channel AI algorithm, which can resist 6m/s wind noise. The two microphones work together, whether riding or running, Both can effectively filter out wind noise. 5. 12.4mm large dynamic coil brings a larger vibration area and textured bass. The titanium-coated diaphragm has good rigidity and hardness, and the treble is purer. 6. The independent rear cavity structure ensures excellent dynamic frequency response range and sound consistency, making the high, mid and low frequencies distinct and the sound more three-dimensional and fuller. 7. Rod-shaped design, optimized with tens of thousands of sets of ear canal data modeling, taking into account both wearing stability and comfort. Adopting a 65:35 internal and external weight distribution, the overall weight moves toward the inside of the ear, making the earphones fit more firmly. 8. The charging compartment adopts a cloud appearance design, which is lightweight and portable. The cloud gap light status light has five lamp beads forming a strip-shaped breathing light effect. After hundreds of combinations over three months, the light effect is natural and comfortable. The high-gloss decorative strips of the headphones adopt nano-coating technology, making them more eye-catching. Specifications1. Earphone input: 5V 150mA (single headphone) 2. Charging box input: 5V 500mA 3. Charging interface: Type-C 4. Single earphone music battery life: about 10 hours (noise reduction off) 5.
