⭕️ Practical Utility Model and Design Registration for the Earaku G9, a detachable microphone headset. This industry-first "two-in-one" design allows for instant switching between a call headset and music earphones. When the boom microphone is attached, high-precision ENC and AI noise reduction are activated, significantly suppressing ambient noise and delivering clear voice transmission. Ideal for online meetings, remote work, and call center operations. Removing the microphone transforms it into a sleek single-ear earphone, perfect for comfortable music listening and video viewing during commutes and travel. The detachable mechanism is simple and provides a secure hold. ⭕️ Call Quality: Equipped with two high-sensitivity microphones. The boom rotates approximately 360 degrees and can be fixed in the optimal position near the mouth, achieving clear audio while suppressing breathing and rubbing sounds. Easy to wear on either the left or right ear, providing a natural voice quality that is easy to hear even during long meetings. ⭕️ Operability: Physical buttons on the main unit allow for intuitive control of volume, play/pause, and call answering/rejecting. Operate with one hand without taking out your smartphone. The one-touch mute function instantly blocks coughs and side conversations, providing peace of mind during meetings and preventing accidental disclosure of personal information. ⭕️ Connectivity: The latest Bluetooth 5.3+EDR provides low latency, low power consumption, and stable connections. Less prone to audio dropouts even in areas with high radio wave interference, such as crowded trains and train stations. Supports simultaneous multi-point connection to two devices, such as a smartphone and PC, for smooth switching during incoming calls. Automatically turns on when powered.
