The Deity V-Mic D4 Mini is an ultracompact on-camera shotgun microphone designed for vloggers, hybrid shooters, and mobile filmmakers who want broadcast-quality sound without carrying bulky audio gear. With its supercardioid pickup pattern and prepolarized condenser capsule, the D4 Mini captures focused, directional audio while rejecting distracting background noise—making it ideal for YouTube content, travel videos, interviews, run-and-gun filmmaking, and everyday shooting.

No batteries are required thanks to its 1–5V plug-in power design. Just plug it into your camera’s 3.5mm input and start recording. The D4 Mini includes both TRS and TRRS cables for instant compatibility with mirrorless/DSLR cameras, smartphones, tablets, and portable recorders (including iPhones when using a Lightning to 3.5mm adapter). At just 28g and only 7.8cm long, it adds virtually no weight to your rig and stays out of frame—even with wide-angle lenses.

One of the D4 Mini’s standout features is its 3.5mm AUX input, which allows you to plug in a wireless receiver or lavalier mic and automatically route that secondary signal to the right channel of your camera—no splitter cable required. This gives you a true two-track recording directly in-camera: one channel from the D4 Mini and one from your secondary mic, perfect for interviews, safety tracks, or documentary-style workflows.

The D4 Mini also includes a faux-fur windshield that provides wind resistance up to approximately 20 mph, making it reliable for outdoor recording. For desktop use, it can be paired with the Deity C21 USB-C cable (sold separately), turning it into a plug-and-play USB microphone for streaming, video calls, and voice-overs without needing a separate audio interface.
