Overview

The Saramonic Blink 500 B4 is an incredibly compact, lightweight, and professional sounding two-person wireless microphone system that was made for the Apple iPhone and iPad. The two included transmitters are small enough to clip directly to shirt collars, and the included RXDi MFi Certified Lighting receiver is so lightweight and unobtrusive that it can easily be used in handheld gimbals. The Blink 500 B4 makes using multiple wireless microphones with Apple devices as easy as possible and it provides broadcast-quality sound in a package that’s amazingly compact and lightweight.

Tiny body, huge sound.
The versatile sub-compact wireless transmitters that come with the Blink 500 B4 have excellent sounding built-in microphones that capture voices perfectly. Small enough to clip to a shirt or slide into a pocket and versatile enough to set on a table or podium, or even used handheld. They also operate as traditional bodypack transmitters with the included SR-M1 omnidirectional clip-on lavalier microphones, providing an even more professional and inconspicuous miking solution. The impossibly compact RXDi dual-receiver plugs directly into the Lightning port of your Apple device and doesn’t require any batteries or charging to operate. It doesn’t have any controls to fuss with, either. You just plug it in, and it works.

So advanced, it’s effortless.
Some wireless microphone systems are complicated to operate and require detailed knowledge of their menus and settings, but the Blink 500 B4 is so technically advanced that it couldn’t be easier to use. Even though there are very few controls to adjust, behind the scenes the Blink 500 is doing a lot to ensure excellent performance. It operates on the interference-free 2.4GHz spectrum, and automatically hops channels to avoid static noise and audio dropouts. Pairing the transmitters to the receiver is simple, and all of the complicated aspects of using wireless microphones happen seamlessly in the background, letting you concentrate on storytelling and getting a great shot.

Perfect levels and power.
One of the tricky aspects of capturing sound for video is controlling the audio levels. Some people speak very loudly, while others speak very softly. That’s why Blink 500 transmitters have easy-to-use gain buttons to raise or lower the levels at the touch of a button, and an intelligent LED display shows you where they’re set. The internal Lithium batteries get 5 hours of life from a charge, and the USB-C charging ports can be used to power or recharge the transmitter in the field with portable USB battery packs. The 10-milliwatt power of the transmitter gives you an impressive range of 98 feet (30 meters) with obstacles, and 164 feet (50 meters) in open spaces.

Handheld gimbal, meet wireless sound.
Handheld gimbals have the amazing ability to deliver cinematically smooth video footage that makes it feel like the camera is floating, but one area where they suffer is audio. It’s simply too difficult to attach external microphones or wireless receivers without throwing off the balance of the device. The RXDi receiver, included in your Blink 500 B4 kit changes this story. It’s small and lightweight enough to remain mounted to your Apple device and won’t interfere with the motors or arm of your gimbal. You can finally capture perfect sound with your mobile gimbal footage with the fantastic ability to put wireless mics on two separate people.

An ideal wireless system.
Even if you shoot video with a mobile phone or tablet, wireless microphones are still completely essential tools for video production, and the fact that the Blink 500 is one of the smallest and most lightweight systems you can get—yet it still delivers professional quality sound—makes it ideal for filmmakers, journalists, vloggers, YouTube creators, corporate video producers, or any content creator that needs an incredibly easy-to-use wireless system that won’t slow them down. If you shoot video with an iPhone and a handheld gimbal, this is the best solution available for perfect sound from two wireless transmitters. This system is small enough to tuck away in a small pocket, so you can effortlessly bring the Blink 500 with you everywhere you go. Plus, the Blink 500 series is an evolving system of products that will soon be expanding, giving users even more options and versatility.
