C3 ANC intelligent noise reduction in earphones--core acoustic principles, unique noise reduction

Comprehensive Overview: C3 ANC passedIntelligent hybrid active noise reductionThe improved system can more effectively reduce the changes in high-frequency and low-frequency sounds. The system uses two headphones embedded microphones to measure the ambient noise input from external sources and sends it to the DSP processing device of the headphone connector to performDecode information and generate a reverse sound mode to effectively offset external noise such as airplanes, trains, subways or buses.The entire process can reduce the ambient noise by 20-30dB (90%) while you enjoy the music, which is equivalent to a distance of 15 times that you exit the noise source.Let you enjoy an immersive listening experience without over-increasing the volume, and enjoy wonderful music.

Kind tips:Active noise reduction function is very effective in the low frequency range, such as: airplanes, trains, subways, buses or offices (near air conditioners) that are not effective at higher frequencies, such as: vocals.

Applicable environment:Travel companion, always going out - During a busy trip or business trip, good relaxation is sleeping and listening to music, but the roar of the plane and the noise of the high-speed rail station really make us irritable and restless on the journey.....Wear noise cancelling headphones, the noise is no longer there, tranquility and music are like shadows, and the journey is no longer boring and tiring.
