This portable wireless microphone uses encrypted UHF signal transmission. The system can avoid signal interference in some complex environments by changing the frequency. The handheld microphone is made of solid metal. The Mic chip is specially designed for human voice, and the restoration and clarity are better preserved. Thanks to the UHF signal transmission, the signal range and stability are better. This wireless microphone can be used in multiple sets at the same time by locking the ID, which greatly improves the scalability.The receiver and microphone of this product are built-in lithium batteries, which can provide 5-6 hours of battery life when fully charged. This wireless microphone is durable and portable and suitable for various occasions, such as parties, meetings, karaoke and other purposes.
