7ryms iRay DW20 Wireless Lavalier Microphone 2.4 GHz 328 ft range

2.4 GHz Dual Lavalier System

The 7ryms iRay DW20 provides two wireless lavalier transmitters and a single receiver that pair automatically on power-up. It targets solo creators, interviewers and small streaming teams who need cable-free audio for cameras, computers or smartphones without managing complex frequency coordination.

Range and Latency Limits

The 2.4 GHz digital link reaches 328 ft in open areas, but walls, bodies and other 2.4 GHz traffic will reduce the practical distance. Latency stays below 20 ms, which keeps dialogue in sync for live streaming yet may be noticeable in tight multi-camera edits that demand sample-accurate alignment.

Battery Life and Recording Modes

Each transmitter runs for roughly 6 hours on its built-in cell and can operate while charging via the supplied 3-in-1 USB-C cable. Mono, stereo and safety-track modes give post-production flexibility, though smartphones only accept mono output and the safety track records at a fixed −6 dB level that cannot be adjusted.
