FAQs
Are these earbuds sweatproof and suitable for workouts
Yes, the Soundcore K20i features an IPX5 water resistance rating, which protects them against sweat, light rain, and water splashes. While they handle workouts and outdoor jogging easily, they are not designed for swimming or full water submersion, and the charging case itself is not waterproof.
Do the Soundcore K20i earbuds support Active Noise Cancellation (ANC)
No, these earbuds do not include Active Noise Cancellation for music listening. Their semi-in-ear design allows ambient sound to enter naturally so you stay aware of your surroundings. However, they do use AI noise reduction across their dual microphones to suppress background noise during voice calls.
Can I use a single earbud independently in mono mode
Yes, both the left and right earbuds support independent single-earbud mode. You can place one earbud inside the charging case to charge while continuing to listen to music or take phone calls using the other.
