Boya 2.4 GHz Dual Lavalier Microphone Wireless BY-WM4 Pro-K3 for iOS

Boya's WM4 Pro-K3 is an inexpensive station set for recording sound during presentations, interviews and conversations with your iPhone. The transmitter and receiver of the WM4 Pro are very compact and connect to each other on the 2.4 GHz frequency. You simply connect the receiver to your iPhone or iPad using the (MFi) Lightning port. You do not need a cable for this, because the receiver of the BY-WM4 Pro-K3 is connected directly to your iPhone/iPad.

Differences from the WM4

The WM4 Pro is the successor to the WM4 and features a higher signal-to-noise ratio, so you hear less background noise. In addition, the WM4 Pro is more compact than the WM4.
