Key features of these systems
• 2.4 GHz wireless transmission (stable, low latency, typically 15–50 m / 50–160 ft line-of-sight range depending on the exact version).
• Plug-and-play pairing (usually auto-pairs when powered on; no app required in most cases).
• Dual-mic support so two people can record simultaneously.
• Noise reduction / DSP processing and the furry windshields for clearer outdoor audio.
• Rechargeable batteries (typically 5–9 hours per charge on the transmitters).
