The Sony WFC710N are Truly Wireless Earbuds they feature advanced Noise Cancelling so can shut out the world around you and allow you to enjoy more of your music. The Dual Noise Sensor filters exterior sound using two microphones so the only thing you hear is your music. A Wind Noise Reduction Structure around the mic reduces distraction when you're active in the outdoors and keeps the focus on your favourite music. Adaptive Sound Control is a smart function that senses where you are and what you re doing then adjusts ambient sound settings for the ideal listening experience. It even recognises locations that you frequently visit such as your workplace the gym or a favourite café and switches to sound modes that suit the situation
