A 2.4 GHz wireless handset microphone is a microphone system where the “handset” (transmitter + microphone) sends audio over a 2.4 GHz digital wireless link to a receive
Specifications
Specification / Feature
Typical / Common Range or Value
Wireless Transmission Band
2.4 GHz ISM band (approx. 2400 – 2483.5 MHz)
Audio Sampling / Digital Format
Digital transmission with ~ 48 kHz sampling rate, 16‑bit or 24‑bit depth (on many units)
Frequency Response (Audio)
Typical: ~ 20 Hz – 20 kHz (some models say 80 Hz–20 kHz)
Polar Pattern (Mic Pickup)
Usually omnidirectional (built‑in condensation/hand‑mic capsule)
Maximum SPL / Max Input Sound Pressure
Often rated around **~ 110 dB SPL** (some up to 120 dB depending on model)
Signal‑to‑Noise Ratio (SNR) / Dynamic Range / Noise Floor
Typical SNR > ~70–90 dB (some better models > 90 dB)
Latency / Delay (Wireless Transmission Delay)
Some models claim low latency — < 20 ms, others as low as ~ 3.8 ms (for premium)
Operating (Effective) Range / Working Distance
Typical effective range (line‑of‑sight/open space) ~ 30 – 100 m (some up to ~100 m or 300 ft depending on model and environment)
Power Source / Battery
Built‑in rechargeable lithium‑ion battery (transmitter & receiver) — no external cables needed.
Battery Life per Charge
Often ~ 5 – 8 hours continuous use on a full charge (varies by model & use)
Charging / Power Supply
Typically USB (or USB‑C) charging for battery-powered units.
Output / Receiver Interface
Analog output: 3.5 mm TRS/TRRS (headphone or microphone output) or other audio‑out connectors depending on the receiver.
Use Case / Applications
Live performance, singing, speaking, streaming, video recording, presentations, events, mobile/portable setups (since it’s wireless and self‑powered)
