The Boya BY-V20 is a dual-channel wireless microphone system designed for creators using Android smartphones, tablets, and other USB Type-C devices. This set includes two compact transmitters and one receiver, allowing you to record two people simultaneously with a 2.4 GHz transmission frequency that reaches up to 100 meters in open areas. Each transmitter is remarkably light at 10.5 g and features a built-in omnidirectional silicon microphone that captures sound from all directions with a 48 kHz sample rate and 16-bit depth. To keep your audio clean, you can activate the one-click noise reduction via the NR button, which helps minimize background distractions. The system is built for convenience with plug-and-play auto-pairing and a receiver that allows you to charge your mobile device while recording. The matte plastic finish provides a professional look, while the integrated clips make it easy to attach the units to clothing. With a battery life of 9 hours per transmitter, this kit is a practical choice for interviews or vlogging where portability and ease of setup are essential.
