LEKATO Wireless Microphone K380S [Set of 2] and an additional receiver. This product originally uses two microphones with one receiver, but since a single receiver doesn't allow for individual volume control of each microphone, I purchased another receiver and paired them separately, using one microphone with one receiver. (It's not possible to have one microphone receive on two receivers.) I've used this a few times indoors for testing, but it's practically unused. (Product Description) ● High Sound Quality and Signal Stability: The LEKATO K380S wireless microphone uses the latest UHF digital signal modulation wireless transmission technology, ensuring high sound quality, stable sound, and low audio transmission delay. The international standard operating distance is 30M. It supports up to 10 sets for simultaneous use in the same area (each set uses a different channel), avoiding interference signals at any time. ● Rechargeable and LED Display: Both the microphone and receiver are rechargeable. There's no need to buy batteries. The microphone battery lasts for about 30 hours, and the receiver battery lasts for 15 hours. The display with dual Type-C charging ports can show the battery power and signal strength in real-time. You don't have to worry about it suddenly not working. ● With Receiver: The rechargeable UHF dual wireless microphone not only requires no setup but also eliminates the need to buy batteries. It has a very convenient plug-and-play function. ● Suitable for Many Occasions: Equipped with a 6.5mm jack output, it can be connected to speakers, recorders, power amplifiers, mixers, PA speakers, bus/car audio, and DVD players for enhanced connectivity. It's more fun and easier to use. - Included: 2 microphones, 2 receivers, USB charging cable, user manual Thank you for looking.
