Overview

The Neewer CM28 Wireless Lavalier Microphone System is a dual-transmitter, single-receiver setup designed for content creators, interviewers, and anyone who needs reliable wireless audio capture. Each compact transmitter clips onto clothing or can be held by hand, and both can operate simultaneously, making the system ideal for two-person interviews, podcasts, or vlog conversations. With 9 hours of battery life on the transmitters and 8 hours on the receiver, the CM28 comfortably handles full-day shoots without needing a recharge.

What sets the CM28 apart at its price point is the 4GB of onboard storage in each transmitter, which records uncompressed 48KHz WAV audio independently of the wireless link. This means you always have a backup recording even if the wireless signal drops or the receiver disconnects. The built-in noise cancellation chip activates with a single button press, reducing ambient noise for cleaner dialogue without requiring post-production cleanup. With a transmission range of up to 656 feet (200 meters) in open environments and compatibility spanning iPhones, Android devices, PCs, Macs, and DSLR cameras through included adapters and cables, the CM28 provides a versatile and self-contained audio solution straight out of the box.
