The Comica Vimo S-MI is a 2.4G dual-channel mini wireless microphone system designed for professional audio recording. It boasts a compact and lightweight design, making it highly portable and suitable for various recording scenarios, including use with computers and phones.
Function Description:
The Vimo S-MI system consists of two transmitters (TX), one receiver (RX), and a rechargeable storage case. The transmitters are equipped with internal microphones and can be easily clipped onto clothing, such as a collar, with the internal mic pointing towards the sound source. They feature a mute/denoise/pairing switch button, allowing users to short press for muting, long press for pairing when unpaired, and long press for denoise when paired. A working status indicator on the transmitter blinks blue slowly when unpaired, rapidly when pairing, shows blue when paired, green when denoise is on, and red when muting.
The receiver (RX) is designed to attach to Lightning devices (iPhone/iPad) via its Lightning plug. It includes a charging/monitoring port, a transmitter volume control knob for synchronous adjustment of both transmitters, and a mono/stereo switch button. The receiver also has a mode indicator that shows blue in mono mode and is off in stereo mode, along with transmitter 1/2 pairing indicators that blink blue when unpaired and show blue when paired.
The rechargeable storage case serves multiple purposes: charging the transmitters and receiver, storing them, and monitoring their power levels. It features a Lightning port and a USB-C charging port for charging the case itself. A battery level indicator button allows users to check the battery level of the charging case and the transmitters. The case displays the charging case battery level (0-100) and individual battery levels for each transmitter via four power indicator lights, where each light represents 25% of the power. The case also includes a restoration hole.

Usage Features:
- Mini and Lightweight: The microphone system is designed for maximum portability.
- Magnetic Integrated Microphone: Unique design for easy attachment and use.
- Broadcasting-level Sound Quality: Achieves high-quality audio recording with 48kHz/24bit resolution.
- USB Digital Output: Universal compatibility for computers and phones.
- Stepless Volume Adjustment: The receiver's knob allows for precise and synchronous volume control of both transmitters. Turning counterclockwise increases volume, and clockwise reduces it.
- One-key Muting and Denoise: Transmitters offer quick access to mute and denoise functions.
- USB-C Charging/Monitoring Port: The receiver's port supports pass-through phone charging while monitoring.
- Zero-latency Monitoring: Users can monitor audio in real-time without delay.
- Mono/Stereo Switch: The receiver allows switching between mono and stereo modes for flexible audio output.
- Rechargeable Storage Case: Provides convenient charging, secure storage, and power monitoring for the entire system.
- Extended Duration: Offers up to 15 hours of use, with support for using the device while charging.
- Low Latency: Ensures minimal delay (< 20ms) for synchronized audio.
- Wide Working Range: Operates effectively up to 200m in open areas.
- Pairing: All units are pre-paired at the factory. For re-pairing, a long press on the TX pairing button initiates the process, indicated by blue lights on both TX and RX upon successful pairing.
- Monitoring/Charging Methods:
- Method One: Connect USB-C headphones to the receiver for monitoring, or connect a power bank/DC power using a USB C-USB A charging cable to charge the mobile phone.
- Method Two: Connect 3.5mm headphones through the included 2-in-1 charging/monitoring adapter cable for monitoring, and simultaneously connect a power bank/DC power to charge the mobile phone.
Maintenance Features:
- Charging Case: The case recharges the transmitters and receiver, ensuring they are ready for use. It can fully charge two transmitters and one receiver twice.
- Battery Level Indicators: The charging case provides clear indicators for its own battery level and the battery levels of the transmitters placed inside, helping users manage power effectively.
- Restoration Hole: A restoration hole is present on the charging case for potential troubleshooting or resetting purposes.
Important Notices:
- Maintain a face-to-face orientation with the receiver during use to avoid signal breakpoints, which are normal for 2.4G wireless characteristics.
- The transmitter's charging indicator may show inaccurate battery levels initially due to lithium battery characteristics; a full charge takes over two hours if completely depleted.
- STEREO function is not available in single-channel mode.
- Avoid exposing the product to rain, moisture, or other liquids.
- Do not use or store the product near heat sources.
- This is a high-precision product; prevent dropping or colliding.
