BOYA BY-WM4 PRO-K3 wireless lavalier mic system for iOS — Lightning receiver, 200 ft range, dual-channel, 11.5-hr battery, plug-and-play.

The **BOYA BY-WM4 PRO-K3** is a compact, entry-level wireless lavalier microphone system engineered for iOS content creators — vloggers, YouTubers, journalists, and TikTok personalities who demand clear, intelligible audio without complexity. It pairs a clip-on omnidirectional lavalier mic and bodypack transmitter with an ultracompact dual-channel receiver that plugs directly into your iPhone or iPad via Lightning, drawing power from the device so there is nothing extra to charge.

With a line-of-sight wireless range of up to 200 ft, up to 11.5 hours of transmitter runtime on just two AAA batteries, and a fully factory pre-paired design for instant plug-and-play operation, the BY-WM4 PRO-K3 removes every barrier between you and broadcast-quality wireless audio. Adjustable input gain, a 3.5 mm headphone monitoring jack, and the ability to expand to a two-person interview setup by adding a second transmitter make it a remarkably versatile system at an accessible price point.

### Key features

- **Plug & Play Lightning Connection:** The ultracompact dual-channel receiver plugs directly into your iPhone or iOS device’s Lightning port and draws power from it — no batteries or extra cables required on the receiver side.

- **200 ft Wireless Freedom:** An operating range of up to 200 ft line-of-sight gives your subject hands-free mobility during demos, presentations, and performances without dropouts.

- **Omnidirectional Lavalier for Consistent Audio:** The clip-on mic’s omnidirectional pickup pattern maintains steady audio levels even when the speaker turns away from the microphone.

- **11.5-Hour Transmitter Battery Life:** Powered by two standard AAA batteries, the bodypack transmitter runs for up to 11.5 hours with an LED indicator to warn you of low battery before it becomes a problem.

- **Expandable Dual-Channel Receiver:** The BY-WM4 PRO-K3 receiver supports two transmitters simultaneously — simply add a second TX4 Pro transmitter (sold separately) to cover a two-person interview without purchasing an entirely new system.

- **Up to 8 Systems in One Location:** Run up to 8 BOYA BY-WM4 PRO systems simultaneously on a busy set, keeping each system at least 16.5 ft apart to eliminate interference.

### Frequently asked questions

**Is the BOYA BY-WM4 PRO-K3 compatible with Android smartphones or cameras?**
The BY-WM4 PRO-K3 receiver connects via a Lightning port, making it specifically designed for Apple iPhone and compatible iOS devices. It is not plug-and-play with Android phones or cameras without an adapter. For camera or Android use, consider other variants in the BY-WM4 PRO lineup.

**Can I record two people at once with the BOYA BY-WM4 PRO-K3?**
Yes. The receiver is a dual-channel unit capable of handling two TX4 Pro bodypack transmitters simultaneously. The K3 kit includes one transmitter; simply purchase a second TX4 Pro transmitter separately to cover a two-person interview or dual-presenter shoot.

**How long do the batteries last and what type does the transmitter use?**
The bodypack transmitter runs on two standard AAA batteries and delivers up to 11.5 hours of continuous use. An LED indicator on the transmitter shows both power status and low-battery warnings so you are never caught off guard during a shoot.
