Technical Specifications

Battery Capacity: 65mAh per microphone.
Operating Time: Approximately 4.5 to 6 hours on a full charge.
Charging Time: Roughly 1.5 to 2 hours via a USB-C port.

Core Features

Dual Microphone Configuration: The package comes with two transmitter microphones and one receiver. This setup allows two people to record audio simultaneously, making it highly effective for interviews, podcasts, or joint vlogs.
Intelligent Noise Reduction: Outfitted with an integrated DSP noise-canceling chip and a high-density foam wind muff to suppress background hums and environmental interference.
Broad Device Compatibility: The main receiver plugs directly into USB-C devices (such as Android smartphones, laptops, and newer iPads). The included modular adapter expands compatibility to Lightning-equipped iOS devices.

Performance Notes

Plug-and-Play Design: Once the receiver is attached to your phone and the microphone power buttons are held down, the components automatically pair without needing a third-party app or Bluetooth configuration.
Android Settings Requirement: Certain Android devices (particularly OnePlus, Oppo, Vivo, or older Samsung models) may require you to manually toggle on OTG (On-The-Go) connection in your system settings before the phone registers the receiver.
Camera App Setup: If your phone's default camera application does not recognize external audio input, downloading an alternative application like Open Camera and changing the audio source settings to "External Microphone" usually fixes the issue
