Lightweight and compact, magnetically absorbed The headset has a lightweight design, is exquisite and compact, and is light and comfortable to wear. Open magnetic absorption. Minimalist aesthetics The abundant ventilation holes also make the earphone cavity no longer a closed space, and the diaphragm in the cavity vibrates more fully, further improving the music effect of the earphones. HiFi sound quality, excellent sound quality Graphene dual-magnetic sound unit, high and low sounds are equally high quality The ultra-thin graphene diaphragm has fast response and high rigidity, making the treble more natural and louder. The dual magnetic unit brings high dynamic amplitude and reduces distortion. Dynamic adaptive EQ compensation, stable sound quality The earphones automatically calculate the frequency response of the user's ear canal and dynamically and adaptively adjust the bass compensation coefficient to reduce sound leakage and achieve stable and consistent sound quality during jogging. *The adaptive EQ function needs to be downloaded from the Xiaomi Headphones APP and turned on in the APP. Xiaomi Headphones APP supports mobile phones with Android 6.0 or above, but does not support iOS yet. Xiaomi debuts LHDC 5.0 ultra-clear transmission, Hi-Res Audio Wireless certification The headphones support the LHDC5.0 ultra-clear transmission protocol, with a sampling rate up to 192kHz, 6 times the details of CDs, ultra-high-definition audio, and ultra-low distortion. * LHDC high-definition audio needs to be turned on separately *Mobile phone models that support LHDC 5.0 192kHz are as follows: Xiaomi 13 Ultra, Xiaomi 13 Pro, Xiaomi 13. Other models are being adapted gradually. The mobile phone models that support LHDC 4.0 96kHz are as follows: Xiaomi13 Pro, Xiaomi 13, Xiaomi MIX Fold 2, Xiaomi 12S Ultra, Xiaomi12 Pro, Xiaomi 12S, Xiaomi 12, Xiaomi 12X, Xiaomi MIX4, Xiaomi 11 Ultra, Xiaomi 11, Redmi K40 Pro, Redmi K40, Xiaomi10 Extreme Commemorative Edition, Xiaomi 10 Pro, Xiaomi 10S, Xiaomi 10, Redmi K30S Extreme Commemorative Edition, Redmi K30 Pro.

The details are subject to actual experience. * 6 times the detail of CD refers to 24bit/192kHz compared to 16bit/44.1kHz of ordinary CD. The information density is about 6 times. * LHDC 96kHz/192kHz will bring a better sound quality experience, but it is greatly affected by Bluetooth and will automatically switch to a lower sampling rate when reconnecting. The actual experience shall prevail. Semi-in-ear, comfortable noise reduction, balanced ear pressure, more comfortable to wear Your Xiaomi Buds 4 can obtain the current wearing status by identifying "ear canal structure", "wearing style" and "environmental noise", and then adjust the noise reduction depth in real time to balance ear pressure, so as to achieve both comfort and noise reduction. *Please keep the earphones tightly fitted when wearing them. The semi-in-ear active noise reduction effect is susceptible to noise depending on the size of the ear. The details are subject to actual experience. *When you wear it and turn on noise reduction, the adaptive noise reduction algorithm has a 1.5s delay, after which it can find parameters suitable for your ear canal structure and wearing status. *The "mild" and "balanced" noise reduction functions need to be turned on in the Bluetooth settings page of the adapted model (see the bottom of the page for specific adapted models), or in the Android Xiaomi Headphones APP. 3Mic+ AI call noise reduction, AI call anti-wind noise The headset has 3 built-in microphones and is equipped with an AI noise reduction algorithm. The call noise reduction can cover most noise scenarios in daily life. The unique "T-shaped" air duct structure, combined with the AI anti-wind noise algorithm, can withstand wind noise up to 32.4km/h. When calling in a windy environment, the other party can clearly hear your voice.tookfun *32.4km/h wind speed data comes from the test of the China Institute of Metrology. The actual effect depends on the user’s It varies depending on ear size, ear canal structure, wearing posture, exercise and other conditions. Through the built-in six-axis sensor, the headset intelligently identifies and dynamically tracks the head direction, and supports horizontal 360° rotation and positioning, bringing an immersive experience of three-dimensional surround. Independent spatial audio, free experience across devices Xiaomi's innovation [Independent Spatial Audio] gives the headset the ability to independently calculate spatial audio. That is, after the mobile phone is turned on, spatial audio can also be realized by connecting to other devices such as TVs, projections, and game consoles. *To enable independent spatial audio, you need to adapt your Xiaomi phone to the Bluetooth settings page or download the Xiaomi Headphones APP.
