feature: Lighting color can be customized through Thundercloud 3 and linked with the lighting of your RAZER CHROMA device. The two cat ears and the ear cups on both sides can display different colors independently to create your own lighting combination. Whether you are posing for live broadcast or shooting, you can match different styles to make you full of energy. The newly upgraded body is softer, lighter and more durable. Thickened memory foam head beam pads fit the head shape of each "cat" for more comfort! The cooling gel earmuffs on the skin surface can effectively dissipate heat, reduce the heat accumulation in the ears, quickly evaporate sweat and conduct heat. The one-way ECM pickup mode makes it easier to collect ambient sounds, and the one-way range is wider to restore your voice clearly. The retractable ANC active noise reduction microphone design, combined with the headphone cover button, makes the control more convenient. Stereo (2.0) consists of left and right channels, usually playing the original sound directly, which is the basic choice for game entertainment. The virtual surround sound (5.1/7.1) drive unit horizontally forms a multi-directional virtual channel, which is suitable for judging the sound source orientation in FPS games. Spatial sound (requires content support) integrates object and scene-based audio to represent the position of upper and lower sound sources, creating a 3D stereo channel. Use Bluetooth 5.0 for wireless connection to ensure reliability and stability while maintaining low power consumption.
