I've used it at home several times. It's very convenient! A wireless guitar system with high-quality 24-bit 48KHz audio broadcasting. You can freely walk around the stage for a truly dynamic performance. The red light is on while charging, and the green light turns on when charging is complete. With a 190° rotatable plug design, it's suitable for electronic drums, passive pickup guitars, bass guitars, and other electro-acoustic instruments, providing dual-channel surround sound that gives music a sense of depth and space. It employs advanced technology, with a high-frequency delay of less than 6ms, no delay, and no signal loss. The effective outdoor transmission range exceeds 100M. It allows your guitar to deliver excellent sound quality and brilliance during performances and practice. Built-in rechargeable lithium battery, long working hours, and comes with a Type-C cable for convenient charging. The Type-C cable can charge two devices simultaneously. Supports 4 sets of devices working simultaneously, 1-to-1 mode, or one transmitter to multiple receivers mode. Low latency, no signal loss, and low noise. Plug and play, you can start playing in seconds.
