With a longer operation distance and a battery life of up to 7-hours, users can take wider and more expansive shots without fear of dropouts and have the ability to shoot for an entire day on one charge.
 
The BY-XM6-S4 kit’s receiver(RXD) is designed for iOS devices with a lightning port. The transmitter can be connected automatically when powered on and plugged into the device. No extra cables, APPs or Bluetooth is needed, just plug in and get started to work. Feature with a 3.5mm headphone output on the receiver, it lets you monitor the recording in real-time to ensure you sound great every time. The receiver also features a selectable Mono / Stereo output setting, allowing you to isolate each person's dialog and adjust each level individually in post-production.
 
With a vivid and easy-to-read OLED display on transmitter and receiver, users can adjust the signal transmission precisely. And the transmitter is designed with a built-in omnidirectional microphone, so users can clip the transmitter on the collar to pick up sounds, while they can also plug a lavalier microphone into the transmitter's MIC IN input jack for sound capturing. The BY-XM6 series comes with a complete set of accessories in each package, such as a lavalier mic and charging cables, which is a cost-effective choice.
