Saramonic Blink 500 ProX Overview

A 2-Person Wireless Audio System for iOS Mobile Content Creation
Ideal for content creators, videographers, journalists, vloggers, podcasters, and live streamers, the Saramonic Blink 500 ProX B4 is a true-wireless, digital microphone system that offers a complete, cost-effective solution for recording clear-sounding two on-camera personalities directly to an iOS phone or tablet equipped with a Lightning port.

The transmitters feature built-in mics and are paired with the receiver at the factory, making the system easy to use for anyone, and delivering reliable wireless transmission with a clear sound at a distance up to 328'. Built-in rechargeable batteries in the transmitters provide up to 10 hours of operation, while the receiver is powered via the Lightning port. The included storage case features a built-in battery to recharge the transmitters and provides 35 hours of shooting time between charges.

2 Clip-On Transmitters with Built-In Mics + 2 Discreet Lavalier Mics
  • Each of the compact, clip-on transmitters can be quickly attached to subjects for fast, run-and-gun-style shoots; you can clip it to clothing, slide it into a shirt pocket, place it on a podium, or hold it in your hand. 
  • Its built-in miniature condenser microphone captures clear and natural voice tonality. The mic's omnidirectional polar pattern picks up sound in all directions, making it easy to position on your talent and get high-quality, intelligible speech. 
  • For a more discreet look, you can plug the included omni lavalier microphone into the transmitter's 3.5mm input jack. The input can accept mic- or line-level signals, making it fully capable of accommodating a variety of external sources, including an audio feed from a mixer or receiver.
  • Since your subjects may speak at very different volumes, Saramonic outfitted the Blink 500 ProX TX with dedicated gain buttons to allow quick and effortless adjustment of the signal level. Utilize the tactile mute function to cut the signal in a hurry without having to adjust the volume.
  • The high-contrast OLED screen shows real-time input metering, input-gain level, mute icon, wireless strength, and battery life.
  • An internal 10-hour lithium-ion battery keeps you going on extra-long shoots or multiple run-and-gun gigs in a day. Recharge the battery via the USB-C port. The transmitter can also be powered via USB, even while in use, giving you near unlimited operating time.
  • A furry windscreen is included for each mic/transmitter to reduce wind noise on outdoor shoots. A foam windscreen is also supplied for each lavalier microphone.
Dual-Channel Receiver with Lightning Connector
  • Simply plug the dual-channel receiver into the Lightning port on your Apple mobile device, the Lightning port supplies the receiver with power and provides a cable-free digital connection to your phone or tablet.
  • Just power up the receiver and transmitters to access reliable wireless audio functionality in an instant.
  • Advanced technology invisibly handles the complicated tasks such as switching channels to avoid dropouts, leaving you with a streamlined and simple system that requires no tedious manual configuration.
  • The separate 3.5mm headphone jack allows for headphone monitoring.
Quality Sound for 1- or 2-Person Shoots
  • Blink 500 ProX systems utilize 16-bit / 48 kHz digital audio resolution to give you quality sound at a budget-friendly price point.
  • Compared to the built-in microphones on cameras and mobile devices, Blink 500 ProX systems offer considerably improved fidelity and clarity with less noise.
  • Within the 2.4 GHz spectrum, the Blink 500 ProX boasts automatic channel hopping to mitigate noise and dropouts at a line-of-sight distance of up to 328 feet, double the maximum distance of the standard Blink 500. For optimal performance, environments with limited Wi-Fi / 2.4 GHz traffic and minimal physical obstructions are recommended.
  • Since the Blink 500 ProX receiver is a dual-channel receiver, it can simultaneously handle two Blink 500 ProX wireless transmitters for 2-person recordings.
  • The receiver features a selectable mono/stereo output mode, allowing it to appropriately feed signal from one transmitter into both input channels of your device (via mono mode) or from two transmitters into separate input channels of your device (via stereo mode).
  • If you need to expand beyond that, you can use up to 18 Blink 500 ProX mics at once at the same location.

  • Advanced next-generation 2.4 GHz wireless

Saramonic Blink 500 ProX Reviews

Disappointed

By Kobina
Rated 2 out of 5
Date: 2026-01-06

Bought it hoping to use it with a lighting to type c adapter on my usb devices, both windows and apple, of which I have several. It's not recognized on the iPads. It showed up once in a windows laptop once and disappeared forever. As a test, I used the same machines with the Smallrig S60 WITHOUT A HITCH. Maybe Saramonic wants you to buy the newer version with the usb-tipped receiver. Bad business.

No me funcionan como esperaba.

Los micrófonos no se conectan de manera exitosa, tampoco recogen sonido en lo absoluto. No tengo manera de saber cómo están funcionando los volúmenes ya que no tienen pantalla visible. Totalmente desilusionada con el producto. Muy mal.

How can I adapt Sennheiser lav's MKE40 and MKE2 on the transmitters? It seems they don't connect well.
Asked by: C
Lavaliers with locking Sennheiser-style 3.5mm connectors should be generally compatible with the Blink 500 ProX B2, but the locking ring cannot lock into place as these transmitters have no locking mechanism. Unfortunately there is no way around this, and although we have tested such connectors and found them to work, there is no way to make them lock into place. It would be more ideal to use a non-locking lavalier, such as BH #ROLAVGO.

What is the total onboard recording capacity of the blink 500PROX?
Asked by: Timothy
The Saramonic Blink 500 ProX B2 2-Person Digital Camera-Mount Wireless Omni Lavalier Microphone System is a basic wireless microphone system which does not offer on-board recording directly to the transmitters. However, the Blink 500 ProX System can be used to record audio onto a camera or portable audio recorder when the wireless receiver is connected to the microphone input on the compatible device.

Asked by: Michael
The lavalier microphone cable for the Saramonic Blink 500 ProX B3 Digital Wireless Lavalier Microphone System with Lightning Connector (2.4 GHz) is 3.5 ft. long. You could use a regular 3.5mm extension cable if you need to increase the length.
