IR-300H Professional Infrared Handheld Wireless Microphone850nm interference-free dual-channel dynamic sound reinforcement
850nm lossless infrared transmission | A/B dual-channel anti-crosstalk | High-quality dynamic cartridge | Pure copper fast charging, built for conferences, training and large events.
Pure, Interference-Free Infrared
850nm infrared technology gives strong penetration and high confidentiality. The signal is immune to RF interference from phones, Wi-Fi and radio, eliminating crosstalk entirely.
Eco-friendly · No radiationProfessional Dynamic Pickup
A high-quality dynamic cartridge with a frequency response optimised for the human voice: bright mid-highs, full lows, and effective suppression of ambient noise and howling.
Hi-Fi · Anti-howlingA/B Dual-Channel Flexibility
Two independent frequencies let two microphones operate in the same room without intermodulation interference, ideal for dual hosting and Q&A sessions.
Dual mics · No interferenceEfficient Charging System
Dedicated pure copper charging contacts at the base offer wear resistance and very low contact resistance. With the CD-4 dock, a full charge takes 2.5 hours for about 6 hours of use.
Pure copper · Long runtime- Composite body balancing durability and signal — The barrel uses a special infrared-transmissive flame-retardant PC plastic for lossless IR emission, combined with a high-strength aluminium alloy grille and frame for drop and impact resistance.
- Pure copper contacts built to last — Unlike ordinary plating, the dedicated pure copper contacts resist oxidation and conduct exceptionally well, sharply reducing poor-contact failures and extending service life.
- Broad system compatibility — Works with mainstream infrared receivers, so legacy upgrades and new deployments connect seamlessly and procurement costs stay low.
- Clear status indication — On the CD-4 dock, simply place the mic to charge: red while charging, green when full, making daily management effortless.
Matching Accessory: CD-4 Desktop 4-Channel Charging Dock
The CD-4 dock is the ideal partner for the IR-300H, designed for centralised device management in high-use settings such as conference rooms and training rooms.
- 4-channel independent charging — Charge two IR-300H microphones and two spare 18650 cells at once, greatly improving multi-device battery management.
- Type-C 65W fast charge — Supports Type-C 65W input (DC 5V/4A), cutting charging downtime substantially.
- Professional-grade contacts — Pure copper spring contacts in the mic bays and nickel-plated plates in the 18650 slots resist oxidation and conduct reliably.
- Precise output control — Mic bays output DC 5V/500mA; battery slots output DC 5V/800mA, protecting battery health and preventing overcharge.
- Intuitive status LEDs — Each charging bay has its own LED: red while charging, green when full.
- Compact desktop design — Saves desk space and suits fixed installations such as conference podiums and studio consoles.
Optimised for Varied Scenarios
The IR-300H paired with the CD-4 dock delivers clear, crosstalk-free, high-fidelity sound. A/B dual channels handle interaction, while pure copper contacts keep the system running all day. From formal business meetings to lively training sessions, it provides professional, dependable audio.
Build a Crosstalk-Free, High-Fidelity Audio Space
