Noise reduction technology: an ally for your conversations

This technology has become a benchmark in the smartphone industry. By identifying unwanted sounds, the secondary microphone neutralizes these noises to enable a better quality conversation. For example, imagine you’re on a crowded subway: thanks to this technology, your calls remain audible despite announcements and the surrounding hubbub. This innovative system activates discreetly with each call.

A future where calls will be even clearer?

With technological advances, noise reduction continues to improve. New algorithms and even more precise microphones are being developed to make calls ever more fluid and intelligible. Future smartphone models will likely incorporate even more powerful microphones, or even an adaptive noise reduction system capable of adjusting filtering in real time based on the noise level of the environment.

In short, this small, discreet hole is far from insignificant: it guarantees the quality of your calls and preserves your conversations, even in the middle of the din.
