NEEWER Wireless Lavalier Microphone System KM18

NEEWER KM18 is a compact wireless lavalier microphone system that delivers studio-style audio for phones, tablets, and computers with up to 200 m forward range and a 24-hour total battery life in its charging case.

Whether you're vlogging, live streaming, interviewing, or teaching online, the KM18 is built to simplify high-quality voice capture. The kit pairs two tiny transmitters with a single USB-C receiver for plug-and-play use on modern phones, tablets, and laptops. Lightweight transmitters clip or magnetically attach to clothing, offer noise cancellation and one-click mute, and recharge inside a display-equipped charging case so you can record longer without interruptions.

How easy is it to set up the NEEWER KM18 with my phone or laptop?

• Automatic transmitter/receiver pairing — no manual Bluetooth pairing needed
• Compatible with common apps: Zoom, TikTok, Instagram Live, YouTube, podcasting apps

What audio quality and noise control can I expect from the KM18?

KM18 captures clear, natural-sounding speech with an omnidirectional condenser capsule and 48kHz/24-bit audio. Built-in noise cancellation and a single-click mute give you quick control over background sound and recording interruptions.

How long will the batteries last and how does the charging case work?
