The Xiaomi Buds 5 wireless earbud headphones connect to any device that has Bluetooth. They are a suitable choice for running or other athletic activities, as they are protected against sweat and rain. They can connect to 2 devices simultaneously, allowing for easy switching between them. They feature Active Noise Cancellation (ANC) which blocks external noises in environments such as public transportation, so you can better hear your music or calls, while the microphone noise reduction function helps your conversation partners hear you clearly.
