The DJI Mic Mini 2 offers few surprises but still feels like a bargain

Design

• Transmitters feature new interchangeable panels 
• Transmitters weigh 11g and clip easily to clothing
• No visible gain level on receiver

The Mic Mini 2 transmitter bears a closer family resemblance to the full-sized DJI Mic 3 than it does to the original Mic Mini, though the key cosmetic distinction is, of course, the aforementioned swappable front panels.

These snap on and off magnetically with minimal effort, and while the practical case for swapping colours mid-shoot is hard to articulate, they add a degree of personalisation that should appeal to certain creators. The transmitters themselves weigh just 11g without accessories, and I found them to be genuinely unobtrusive when clipped to my collar or magnetically fastened to my shirt front.

Neither transmitter nor receiver features an LCD display, which means there’s no way to monitor audio levels directly on the hardware – a limitation shared with the original model, and one that reflects the Mic Mini 2’s positioning below the more feature-rich Mic 3.

The standard receiver connects to cameras via a 3.5mm jack and to smartphones via USB-C, with a Lightning adapter also available (though this is sold separately rather than included in either bundle). A dial for manual gain adjustment is present, alongside power and pairing controls.

The smaller mobile receiver, included in the single-transmitter bundle, is a notably streamlined unit designed purely for attachment to a phone.

Features

• Up to 400m range with standard receiver
• Up to 48 hours of use when used with the charging case
• Works seamlessly with OsmoAudio ecosystem products

The Mic Mini 2 records at 48kHz 24-bit quality, just like its predecessor, and offers a transmission range of up to 400 metres with the standard receiver, or 300 metres with the mobile receiver.

Battery life stands at 11.5 hours for each transmitter and 10.5 hours for the receiver, with the charging case extending total runtime to 48 hours – again, all the same figures as you’d find with the original Mic Mini. Fast charging is supported, with around an hour of use available from just five minutes on charge.

Two levels of active noise cancellation are built in, suited respectively to quieter indoor environments and noisier outdoor conditions. The system integrates with DJI’s OsmoAudio ecosystem, enabling direct wireless connection (i.e. without a receiver) to compatible devices including the Osmo Action 6, Osmo 360 and Osmo Mobile 8 gimbal.

The three voice tone presets are the only genuinely new feature of note that I could find, though in testing, the differences between Regular, Rich and Bright are too subtle to be considered consequential.

Audio quality

• Crisp, clear audio with a pleasing warm tone
• Effective noise cancelling
• Functionally identical to the original Mic Mini

Tested across multiple days with an iPhone 13, DJI Osmo Action 6 and Panasonic Lumix GH6, the Mic Mini 2 performed consistently well. Audio was clear and detailed across all three devices and connection methods, representing a substantial step up from the built-in microphones found in smartphones and consumer cameras. There’s a pleasant warm tone to the vocals, no matter which of the presets you use.

The active noise cancellation, meanwhile, acquitted itself reasonably in moderately noisy conditions. In my home office, a running fan in the background was reduced to a manageable level, if not eliminated entirely. Outdoor performance in light wind was similarly competent with the supplied windscreen fitted.

There is nothing here, however, that meaningfully distinguishes the Mic Mini 2’s output from that of the original Mic Mini. The core audio performance is essentially the same – which is no bad thing, I suppose.
