Is the DJI Mic 2 good for singing and music?

The DJI Mic 2 is fine for singing in videos: covers, worship sets, busking clips, lessons and behind-the-scenes content. It records a full 50 Hz to 20 kHz range with low cut off, handles up to 120 dB SPL, and each transmitter can record a 32-bit float backup that's hard to ruin with a loud note. It isn't a studio vocal mic, though. It's a clip-on omnidirectional mic, so it picks up the room and instruments, and chest placement colors the voice. For music, turn noise cancelling and low cut off and set the gain low.

DJI Mic 2 specs that matter for music — From DJI's Mic 2 specs and manual. Turn off noise cancelling and low cut for music, and use the 32-bit float backup for loud passages.

Settings for singing

On the receiver, swipe down and open Transmitter Settings:

Noise Reduction: off. It's built to remove background noise, and it can treat sustained notes, reverb tails and instruments as noise.
Low Cut: off if there's bass, piano or guitar. Low cut removes everything at 100 Hz and below. For an a cappella voice in a rumbly room, you can leave it on.
Transmitter Gain: low. Sing your loudest passage and lower the gain until the bar stays out of the red. DJI notes this also sets the internal recording level.
32-Bit Float Recording: on, and start internal recording. If a high note clips the wireless track, the float file usually still holds it.

On Receiver Settings, use Safety Track with one singer. DJI's manual says it sends the main signal on the left and a copy 6 dB quieter on the right, as a fallback for loud moments.

Placement

Clip it high on the chest, centered, facing up toward the mouth. Too close and it can distort on loud notes. Too low and it sounds thin and roomy.
Keep hair and clothing off the mic. Movement while singing makes rustle.
For a closer, cleaner vocal, plug a lavalier into the transmitter's 3.5 mm input. DJI's own lavalier is made for this.
Very loud singers: if the voice still distorts after lowering gain, move the mic a little farther from the mouth. 120 dB SPL is the mic's ceiling.

Singer plus instrument

With two transmitters, record the voice and the instrument separately:

TX1 on the singer.
TX2 near the instrument, such as clipped to the guitar strap facing the sound hole, or on a stand near the piano.
Receiver in Stereo, so each source records on its own channel.
Balance them in the edit.

Remember both transmitters are omnidirectional, so each picks up some of the other source. Keep them apart where you can.

Monitoring

Plug headphones into the receiver's monitor port and adjust Volume in Receiver Settings. DJI doesn't publish a latency figure for the Mic 2. If hearing yourself through the wireless system feels slightly late while singing to a backing track, monitor the backing track directly and listen back afterward.

When to use something else

Studio vocals: a dedicated vocal mic on a stand, into an interface, gives a richer, more controlled sound.
Loud band rehearsal: drums and amps will bleed into every clip-on mic.
Live sound through speakers: a clip-on omni mic is prone to feedback near PA speakers.

Mic Mini for music?

The Mic Mini shares the 120 dB SPL limit and omnidirectional pickup, but has no internal recording and no on-screen meters. For music, where levels jump around, the Mic 2's 32-bit float backup is the reason to choose it. See DJI Mic 2 vs Mic Mini.
