Xiaomi Redmi Buds 4 wireless headphones feature hybrid active noise cancellation technology, feedback and direct microphones work together to effectively separate ambient noise. Whether you're outdoors, on the bus or on the subway, with just one touch, you'll get noise reduction of up to 35dB.
Redmi Buds 4 intelligently switches between 3 levels of ANC in AI algorithm-assisted adaptive mode and offers a more comfortable noise cancellation experience. The AI voice algorithm accurately distinguishes between human voice and ambient noise, so even in noisy environments, the listener will hear your every word, loud and clear.
The Xiaomi Redmi Buds 4 's large dynamic driver makes your voice sound clearer, lower frequencies fuller and highs brighter. Choose a high-quality 0.006mm diaphragm to bring out even more detail in your favorite music.
Enjoy up to 6 hours of use on a single charge and up to 30 hours of battery life when paired with the charging case, so you can enjoy great music both day and night. After just 5 minutes of charging, you can play music for 1 hour. Take a break, then go back to where you left off.
All you have to do to pair is open the charging case near your smartphone and tap the screen when the pop-up appears. The wireless headphones can be paired with various Xiaomi/Redmi products, such as smartphones and laptops.
Redmi Buds 4 uses Bluetooth®5.2 to provide reduced audio latency in the game, so you can make decisions earlier, experience more consistent output and stay ahead of the game.
The Xiaomi Earbuds app helps you customize noise cancellation and touch controls on the Redmi Buds 4 wireless headphones. You're in control - adjust settings for optimal sound and install firmware updates online
