Intelligent Scene Noise Reduction Optimisation: real-time analysis of environmental noise types through AI algorithms, automatic switching of depth noise reduction, human voice shielding, intelligent transparency mode, no need for manual adjustment; Anti-Wind Noise Black Technology: Built-in air pressure sensor + dual microphone array reduces wind noise by 90% and improves call clarity by 80% when riding/running (wind speed 15m/s). Pass-through mode upgrade: Directional human voice enhancement: after turning on the pass-through mode, the clarity of the human voice in front of you will be increased by 2 times, and at the same time, side/back noise will be shielded, so it is safer to cross the road and communicate with others; Ambient sound customisation: Support APP to adjust the intensity of the pass-through mode (0-10 levels), to adapt to different scenarios such as coffee shops, outdoor sports and other needs. Exclusive device pop-up window: Open the cover and connect: support mainstream mobile phone systems (iOS/Android), after the first pairing, open the cover and instantly pop up the headset animation pop-up window, displaying the power, noise reduction status and connection tips; Personalised pop-up window theme: 10+ sets of dynamic pop-up window skins (minimalist tech/cartoon IP/starry sky theme) are provided in the APP, supporting customised image upload; Seamless multi-device switching: the pop-up interface can switch paired devices (e.g. mobile phones/tablets/computers) with one click, so you don't need to re-pair for cross-device use.
