ENx technology is a sound enhancement algorithm found in some of the latest boAt earphones and earbuds. It stands for Environmental Noise Cancellation and is designed to suppress unwanted background noise and help capture your voice clearly during voice calls or video meet-ups. The technology uses multiple microphones to detect and cancel out external noise, allowing for clearer communication. Currently, boAt features models with 2 mic ENC (1 mic on each earbud) and 4 mic ENC (2 mics on each earbud) . The technology also has low latency, making it suitable for gaming. ENx technology is a useful feature for those who work from home or anywhere and need to communicate clearly with others.
