DJI Mic kit first look: Is this a RØDE Wireless GO II killer?

May 10, 2022 admin

Just as DJI’s launch video for the new Mini 3 Pro drone was coming to an end, I took delivery of another DJI product — the DJI Mic.

As the name suggests, it’s a microphone.

Actually, it is two wireless microphones and a wireless receiver in a charging case. There are also a couple of magnets to allow you to attach the mics to clothing, a couple of connectors (USB-C and Lightning) to allow the receiver to be attached to smartphones, and a mount to allow the receiver to be attached to a hot/cold shoe on a camera.

My first impressions of the kit are very positive. The presentation of the kit is high-quality and reminds me of an Apple product. The charging case is well made and holds the microphones and receiver in place using strong magnets. When popped into the case, the devices automatically begin charging.

Open the case, and the microphones instantly pair with the receiver.

The wireless transmission makes use of the 2.4GHz frequency band, and DJI claims it is good up to 250 meters.

I’ve been using RØDE Wireless GO and RØDE Wireless GO II microphones for a few years now, and I’ve been pretty impressed by them. They’ve lasted hard use for many months, the audio quality is excellent, and the wireless transmission range is very good assuming you keep things line-of-sight (even a human body getting in the way can block the signal).

Will the DJI Mic set replace them?

Well, right now it’s too early to tell. That said, I have had time to carry out some quick tests and I’m very impressed by both the ease of use and audio quality.

Stay tuned for an in-depth review soon.
