The Xiaomi Mi Earphone Air 2S are true wireless in-ear headphones designed for a seamless daily listening experience. They feature a large 14.2mm composite diaphragm moving coil dynamic driver that covers a frequency range from 20Hz to 20,000Hz, ensuring a balanced sound profile. To maintain high audio quality, these earbuds support LHDC and AAC codecs via a Bluetooth 5.0 connection with a stable range of up to 10 meters. Constructed from lightweight ABS plastic, the white earbuds are comfortable for long sessions and carry an IPX4 water resistance rating, which protects them from splashes and sweat. You can manage your music, calls, and voice assistant through intuitive touch controls, while integrated infrared sensors automatically pause your audio when you remove an earbud. For clear communication, dual-microphone noise reduction helps filter out background sounds during phone calls. The accompanying charging case extends the total battery life to 24 hours, with the earbuds themselves providing up to 5 hours of continuous playback. Charging is flexible, as the case supports both a USB-C cable and Qi wireless charging, reaching a full charge in about an hour. If you are in a hurry, a quick 10-minute charge gives you another 70 minutes of listening time.
