Amazon Drone Deals: DJI Mini 5 Pro Fly More Combo with DJI RC2 now for $1,099!
Wireless microphones are shrinking at an alarming rate, and not in a polite, gradual, Moore’s Law kind of way, but in a reckless, almost competitive sprint toward invisibility, the kind that makes you wonder if engineers are doing this for creators or simply to prove they can.
SmallRig’s new S70 wireless microphone, priced at $89, enters this shrinking battlefield aiming straight at compact rivals like the DJI Mic Mini and Insta360 Mic Air, and it does so with a straight face, studio grade specs, and a physical size that feels like it should come with a tracking beacon, as their Press Release just launched.
This is no longer about portability. This is about whether you can still find your microphone after putting it down for five seconds.
Smaller Than Your Excuses for Bad Audio
The SmallRig S70 is officially tiny. The mic head measures just 8.8 millimeters, which places it somewhere between “minimalist design object” and “was this supposed to be here?” It weighs 5.7 ounces, making the DJI Mic Mini, which comes in at around 7.7 ounces, suddenly feel like a legacy product from the early days of YouTube.

At this rate, wireless microphones are on track to become so small that future packaging will include not just cables and windscreens, but a dedicated garment whose sole purpose is holding the mic in place. Not for fashion. For survival.
Despite its size, the S70 records at 48 kHz, 24 bit, handles 120 dB SPL, and captures sound in a full 360 degree pattern, meaning it will faithfully record your voice, your emphasis, and that unexpected background noise you swore was far enough away.

The audio tuning was handled by Grammy Award winning engineer Luca Bignardi, which is significantly more credibility than most creators bring to their first mic test video. There are nine EQ presets, automatic limiting to prevent audio spikes, and three levels of noise reduction, which is essential if you record anywhere that contains humans, vehicles, or life.
Battery Life That Refuses to Quit
Here’s where things get slightly absurd. Despite being smaller than your patience during firmware updates, the SmallRig S70 claims up to 40 hours of battery life when used with the charging case.
Forty hours.

That is long enough to record multiple shoots, forget to charge it, panic slightly, then realize it still has battery left. Wireless range is rated up to 300 meters in open environments, which is more than enough for interviews, vlogging, or walking dramatically away from the camera while finishing a sentence.

The system includes two transmitters, camera and USB C receivers, windscreens, cables, a carry case, and a charging case, all wrapped in a design that avoids logos and comes in multiple colors, because at this scale, blending into clothing is no longer optional, it is essential.

Compared to the DJI Mic Mini, the S70 is lighter, slightly smaller, offers more onboard EQ control, includes physical buttons, and undercuts it on price, while matching core audio specs. DJI still owns the ecosystem polish crown, but SmallRig is clearly playing the “maximum features per cubic millimeter” game, and playing it aggressively.

DroneXL’s Take
The SmallRig S70 is a reminder that the wireless mic market has officially entered its tiny era, where audio quality is no longer the limiting factor, but human eyesight might be.
It delivers serious sound, excellent battery life, and professional features at a price that makes sense, especially for creators who want flexibility without paying a premium for brand gravity. At the same time, it raises an unavoidable question about where this trend ends, because if microphones get any smaller, we may need accessories whose only function is preventing them from vanishing into the couch, the laundry, or another dimension entirely.
For now, the S70 is an impressive, slightly ridiculous, and genuinely useful piece of kit. Just don’t drop it.
