Comprehensive Review and Features
The Blink 500 B4 Ultracompact Dual Wireless Clip-On Microphone System is designed to deliver professional-grade audio and seamless connectivity to Apple's iPhone and iPad devices with Lightning ports. Optimized for mobile filmmakers, vloggers, interviewers, content creators, and broadcast professionals, this cutting-edge system combines easy setup, stellar 2.4 GHz digital transmission, and powerful battery life to provide crystal-clear sound capture for two people simultaneously.
Premium Hardware and Design
The Blink 500 B4 kit includes two clip-on transmitters with built-in omnidirectional microphones, giving you the flexibility to mic speakers discreetly without additional accessories. For even more flexible setups, the system includes two SR-M1 omnidirectional lavalier microphones that connect as bodypack transmitters, allowing versatile usage scenarios.
The receiver (model RXDi) is a battery-free dual-channel device that directly plugs into the Lightning port of your iPhone or iPad, drawing power from the Apple device itself. Its ultra-lightweight, slim profile minimizes hardware bulk, enabling a sleek, fully mobile recording setup. The receiver features an OLED screen to display battery status, audio levels, channel info, and mute status.
Advanced Wireless Technology and Audio Quality
Operating on the 2.4 GHz digital wireless band with Gaussian Frequency-Shift Keying (GFSK) modulation, the Blink 500 B4 guarantees a robust and interference-resistant connection. It automatically selects between 18 frequency channels to avoid signal conflicts, ensuring uninterrupted audio during critical shoots or live streams.
With an industry-standard 24-bit/48 kHz digital audio signal, the system delivers clear, natural sound characterized by wide frequency coverage and a high signal-to-noise ratio (≥84 dB). This means background noise is minimized while voices come through with excellent clarity, making it ideal for interviews, podcasts, live reporting, and content creation requiring pristine sound quality.
User-Focused Features for Professional Results
Each transmitter includes tactile gain controls for quick level adjustment and an intuitive mute button allowing instant silencing without disabling the transmitter. The OLED display shows precise audio metering and battery status, simplifying monitoring so that users can focus on content rather than technical distractions.
Moreover, the RXDi receiver has a dedicated 3.5mm headphone jack for real-time audio monitoring, a critical feature for on-the-spot sound checks and adjustments, supporting mono and stereo output modes depending on your recording preferences.
Extended Battery Life and Convenient Charging
The system boasts a remarkable 10-hour battery runtime per fully-charged transmitter, giving creators the confidence to tackle full-day shoots without interruptions. The included 3000mAh portable charging case can recharge the transmitters up to 3.75 times, effectively extending operation to an impressive 47.5 hours on the go.
The charging case automatically turns transmitters on when opened and off when closed—simple yet effective power management for busy environments. Transmitters also support USB-C charging, allowing versatile recharge methods with common cables and power banks.
Seamless Usage and Setup
Setup is remarkably simple with one-click pairing between transmitters and receiver, making the Blink 500 B4 accessible for professionals and beginners alike. Just plug the RXDi receiver into your iPhone or iPad, power on the transmitters, and you are ready to record high-quality wireless audio without hassle or cable clutter.
The system supports simultaneous dual-transmitter operation with separate levels and mute toggles, giving creators full control over source audio whether shooting two-person interviews, panel discussions, or collaborative podcasts.
