Plug and Play Wireless Microphone with Rechargeable Receiver for 1/4" and 1/8" Output: This wireless microphone is incredibly easy to use. Simply plug the receiver into a karaoke machine, turn on the microphone, and start singing or delivering a speech - it's that simple. The Bietrun wxm 31 wireless microphones are user-friendly, even for those with no prior experience using microphones. There's no need to set up frequency matching, as the microphone and receiver automatically pair.

Lossless Crystal Clear Sound: The wireless microphone karaoke is a dynamic cardioid mic that delivers clear, high-quality sound thanks to advanced audio technology. With a gentle and generous 50Hz–16kHz frequency response and presence boost, the sound is clear and smooth, perfect for family karaoke, small stages, clubs, places of worship, hotels, and gyms.

Ease of Use: The microphone uses 2 AA batteries (not included), while the receiver is USB-C rechargeable. With 15 channels per microphone, you can easily switch between them using the CH button. The microphone is equipped with an LCD screen that displays the channel, battery power, and signal presence. Volume control is managed through the Power Button, with adjustable levels from 1 to 5. This wireless microphone is compatible with karaoke machines, amplifiers, mixers, PA systems, and audio interfaces. Please note that it is not compatible with Bluetooth devices.

Signal Stability and Interference Resistance: The Bietrun dynamic wireless microphone has an operating range of up to 98 feet, making it suitable for both outdoor events (weddings, pool parties, backyard BBQs, etc.) and indoor use (classes, singing, meetings). Operating in a stable UHF frequency band, you can chain up to 15 wireless microphone systems, allowing 15 performers to be on stage simultaneously. However, it's important to lock the ID when using multiple sets.

Precautions: If your microphone has no sound, ensure that both the microphone and receiver have sufficient power. Insert the MIC jack, not an AUX jack. The wireless microphone is not supported on MacBooks.

In summary, the Bietrun wireless microphone with rechargeable receiver offers a plug-and-play experience, crystal-clear sound quality, ease of use, and stable signal performance, making it an excellent choice for a variety of applications, from karaoke to live performances.
