7RYMS iRay DW40 4-Channel Wireless Microphone - Clear Multi-Host Audio

In this review the 7RYMS iRay DW40 is presented as a practical multi-channel wireless lavalier system for creators who need reliable, multi-person audio capture. The kit's single biggest selling point is the included four transmitters and one receiver, which let small panels, podcast guests or multi-subject interviews be recorded simultaneously without scrambling for extra gear. It balances professional-grade sound capture with simple setup and a compact charging case that extends runtime, making it a useful choice for run-and-gun video shooters and podcasters alike.

Key Features

• 4-Channel Recording System: Four transmitters paired to one receiver allow simultaneous recording from up to four participants for interviews, panels, and multi-host podcasts.
• Dual Output Modes: The receiver provides both USB-C digital and 3.5mm analog outputs so it can connect to cameras, phones, and computers without adapters in most workflows.
• 48kHz/24-bit Sound Quality: High-resolution audio capture preserves clarity and detail, useful when audio will be mixed or processed in post.
• One-Click Noise Cancellation: Noise canceling on the transmitter helps reduce background interference when recording in busy or outdoor environments.
• Portable Charging Case: The compact case recharges transmitters and the receiver, extending total usable time and reducing the need for frequent wall charging between sessions.

Who It's For

The DW40 is aimed at independent video creators, podcasters, event recorders and small production teams who need to capture clear dialogue from multiple people at once without complex wiring. Its combination of multiple transmitters and simple outputs means one person can manage a panel or a two-person interview alone and still get separate channels.

Those who should look elsewhere include users who require ultra-long continuous runtime beyond what the charging case provides or professionals demanding built-in multi-track recorder functionality in the receiver; dedicated studio setups or single high-end shotgun microphones may be a better fit for those use cases.

Pros & Cons

Pros

• Included four transmitters provide flexible multi-person recording without extra receivers.
• Good build quality and easy setup makes it accessible to users new to wireless lav systems.
• Real-time monitoring via the receiver's 3.5mm port allows quick checks of audio during recording.
• Digital USB-C output and analog 3.5mm give broad device compatibility for cameras, phones and computers.

Cons

• Battery life per charge is about 5 hours, so heavier users must rely on the charging case for extended shoots.
• The system is focused on lavalier capture; those needing boom or shotgun pickup for distance recording will need a different solution.
