his is a stereo portable wireless in-ear monitoring system that uses UHF digital signal transmission and ultra-low noise floor to achieve almost imperceptible ultra-low latency while ensuring the clarity and high restoration of the sound. The built-in large-capacity battery can ensure long-term battery life. Users can switch between mono and stereo freely. The built-in multi-channel switchable system can avoid signal interference in complex environments. The system is small and easy to take out.Whether it is a personal music lover or a professional stage performance,it can be a good partner for your music journey
