And with 5-minute quick charging, you can top up in a hurry for an extra hour. With Precise Voice Pickup Technology that optimally controls microphones on the outside and inside of the earbud, and advanced audio signal processing, conversations are ultra clear, even in noisy environments. Our noise reduction algorithm was developed with AI machine learning using over 500 million voice samples to suppress ambient noise and extract your voice clearly. Conversation flows freely with easy hands-free calling, now clearer than ever with a high-quality built-in microphone. Multipoint Connection allows the WF-C710N earbuds to be paired with two Bluetooth® devices simultaneously.
