Design and Setup

The Grenaro S12 Wireless Microphone is extremely easy to set up. Connect the receiver to your phone using Type-C connection, attach the transmitter to your shirt and press the button to begin recording. No application will need to be installed on the phone to connect the mic, it will connect automatically in a few seconds. The transmitter is very tiny, very light, and has an easy-to-understand display of the mode, battery, and connection status indicated by LED lights.

 Sound Quality

A type of mic that provides natural clear sound. An independent mic test was done on a laptop and it provided automatic gain control, echo cancellation and noise suppression, as well as 48kHz and 16-bit audio at a 5/5 rating for the price. A three-rate noise reduction to minimize noise from traffic, fans and crowds. It has been called a good buy for “beginner Youtubers and casual creators” by a Klavabogo reviewer.

Filter Heads and Modes

It is an outdoor/indoor recording microphone. The house reduces plosive sounds (e.g., p and b) with the sponge filter head, while the windproof filter head eliminates wind noise out of the house. By pressing the transmitter once, the noise reduction is turned on, pressing it twice mutes the microphone and pressing it three times activates the reverb effect.

The Grenaro S12 Wireless Microphone comes with a battery and range.

Good for most vlogging, interviews and classes, the 65mAh battery provides up to 6 hours of battery life. The included cable can be used to charge the mic and your phone together. The wireless range may be up to 30 metres in open spaces, but walls and crowds will limit the range in actual service.

Compatibility Tips

  • Android: See if the phone has a microphone, if it doesn't, switch on the power to the OTG in the settings menu.
  • iPhone: Only for iPhone 15 and above, which have Type-C connectors, it operates directly. Older iPhones will need a lightning adapter.
  • Adapter Support: The Type-C receiver is intended for use with phones, and compatibility of the adapters should be tested prior to use with a camera.
