SmallRig S70 Reviews

Worth it

By Christopher
Rated 5 out of 5

I had very low expectations from this thing with the price and brand. I am an audio engineer and videographer so I tend to gravitate towards higher level gear. I bought this for a quick job and used it as backup audio on another. Super clean and amazing audio! I had to do very little in post to make my interview sound great. When I used it as a backup, I had a shotgun mic as a main but it had picked up all the terrible HVAC and room noise. This little mic had its room canceling option engaged and not only saved the entire shoot, but the audio quality was amazing. I am using it again as my main mic tomorrow and having the options to “color blend” it in with my subjects clothing will be a great little addition to its already amazing functionality. Honestly, still waiting for a downside to this thing. Battery life and connectivity are great so far. Zero complaints. Buy it as your main mic on a budget or have it as a cheap backup. Cannot go wrong.

Great Price, Good Sound!

These microphones work great! The only feature I wish they had is internal audio recording. However, for the price, it’s hard to beat the discreet design and excellent sound quality. They perform reliably, sound great, and are easy to use. I would definitely recommend them to anyone looking for a quality wireless microphone system without breaking the bank.

Does it search for alternate bandwidths — i.e. could I use two sets of mics separately in the same room without interference?
Asked by: Douglas
The SmallRig S 70 2-Person Wireless Microphone System for Cameras and Mobile Devices (2.4 GHz, Black) is a single-bandwidth system; it does not have an auto-scanning mode. Only one system can be used per location.

Asked by: Richard
The SmallRig S70-C2 2-Person Wireless Microphone System for USB-C Mobile Devices (2.4 GHz) records to a phone via the USB-C receiver. IT does not record internally. For use with a camera see the SmallRig S70 2-Person Wireless Microphone System for Cameras and Mobile Devices (2.4 GHz, Black) (BH #SM5715) which includes a camera mount receiver.

How do you pair this with Nikon Z8 or Z9 during video capture?
Asked by: Biji
The SmallRig S 70 2-Person Wireless Microphone System for Cameras and Mobile Devices (2.4 GHz, Black) comes with a 3.5mm TRS audio cable that would be connected from the receiver into the 1/8'' mic input on the Nikon Z8 or Nikon Z9. The receiver would mount to the accessory shoe on top of the camera. After that, the audio from the wireless system would be recorded with your video on the camera.

Can I monitor the audio from this?
Asked by: steve
There is no headphone output jack on either of the receivers of the SmallRig S 70 2-Person Wireless Microphone System for Cameras and Mobile Devices (2.4 GHz, Black.) You would have to monitor your audio from the destination, if it is a camera, audio recorder or computer. There would be no smartphone monitoring during recording with this wireless system.
