The Boya BY-V4 is a 4-channel portable 2.4GHz wireless microphone system for 3.5mm TRS (camera) devices, supporting up to four lavalier mics simultaneously with dual noise cancellation.

Each transmitter has a 360° rotatable clip for easy attachment and one-click noise cancellation, backed by an advanced high-density spray-proof sponge to reduce wind noise. A stable signal range of up to 200m keeps recordings clear both indoors and outdoors.

The included charging case delivers up to 18 hours of battery life, and audio can be monitored directly through your phone’s speaker without unplugging the receiver.
