A:Answer Hi Jr,
Whether you're taking a long-haul flight or commuting to work, the WCH710N noise-cancelling headphones automatically collect information about your environment and improve the noise-cancelling performance accordingly.
The dual microphones feeding forward and backward mean the WH-CH710N headphones catch more ambient sounds than ever before. So, whether you're trying to block out city traffic or office chatter, you'll be able to get completely lost in whatever you're listening to.
Happy shopping & thanks for your interest in Sony!
Regards,
David
