Record two-person or four-person vlogs and interviews to your DSLR/mirrorless camera or compatible smartphone using the BOYA BY-W4 Ultracompact 4-Person Wireless Microphone System and its four included transmitters with built-in omnidirectional microphones. The system not only includes these four transmitters with ultracompact form factor and back clips for attaching to your talent’s lapel, but it also includes a four-channel receiver with 3.5MM TRRS connectivity. All of the components can communicate from up to 98′ away via 2.4 GHz frequency.

Monitor your audio and record simultaneously using the included 3.5mm TRS male to dual TRRS female monitoring cable. The male connector attaches to your receiver’s 3.5mm TRRS port while the two female connectors accept your headphone or computer input connection. Use the LED indicators on each component to view your connection and battery statuses. Onboard controls on each transmitter allow you to adjust the gain levels or mute the unit. Built-in rechargeable batteries in all units power the system for up to 7 hours at a time, while USB-C charging ports power them back up when depleted.
