Ulanzi J12 Dual Wireless Microphone for Android With Charging Case For Type-C

Two voices, one Android phone — no wires, no syncing in post. The Ulanzi J12 is a dual wireless microphone system built for Type-C Android phones: two transmitters send audio to one slim Type-C receiver, so interviews, two-person podcasts, and co-hosted vlogs capture both voices in one take, straight into your phone. The ulanzi j12 was made for creators who shoot fast and on the go — interviews, Q&A videos, and live streams without a second chance at the take.

Here is what makes this dual kit different from anything with a cable. Each transmitter carries its own built-in 80mAh battery, and the earbud-style 800mAh charging case keeps both mics topped up and pocketable between shoots. Intelligent noise reduction filters out background chatter and wind so your voice stays clear, and omni-directional pickup captures sound naturally from all directions. With a 20-meter stable wireless range, ≤25ms low latency, plug-and-play pairing with no app or Bluetooth, and headphone monitoring through the receiver, the system keeps audio locked to video wherever the shoot takes you.

Two honest framings before the details. First, the Type-C Android identity is exact: this listing is the Type-C Android version of the ulanzi j12 — the receiver plugs into a Type-C Android phone, not an iPhone’s Lightning port. It is NOT the single-mic Ulanzi WM-10 for Android (a single clip-on mic), NOT the Ulanzi WM-10 for iPhone (the Lightning variant), and NOT the Ulanzi A30 or DCM-05 (different Ulanzi models sold separately). Second, everything below comes from the verified research notes — nothing is guessed, and no iPhone or Lightning compatibility is claimed anywhere.

Two Voices. One Kit.

The ulanzi j12 is dual by design: two transmitters, one Type-C receiver, both voices recorded into your Android phone in a single take. That is the whole point of the system — an interviewer and a guest, two co-hosts, a vlogger and a friend — each with their own dedicated microphone, no passing a single mic back and forth, no second audio track to sync in post. The dual-mic architecture above is the defining feature of this kit: interview audio that sounds pro because both sides of the conversation were captured at the same time.

See the whole system in one frame: the earbud-style charging case open with both transmitters docked and ready. This is the kit as it ships — two transmitters, the Type-C receiver, and the charging case — the promo hero above shows the core hardware, and the “Everything in the Kit” section below walks through each piece.

Made for Type-C Android

The ulanzi j12 receiver is a slim stick-like Type-C receiver that plugs straight into your Android phone — plug it in and the system pairs automatically, no app to install, no Bluetooth to wrestle with. The phone sees it as a microphone immediately and you start recording. One important compatibility note, straight from the product page: some phones need OTG enabled before the receiver works (notably some OPPO and VIVO models), and Samsung S8/S9/S20-series phones plus Google phones are listed as incompatible — check your phone model before ordering. This matters because Android audio-over-Type-C is not identical on every handset: if your phone falls in the incompatible list, no adapter will fix it, so the two-minute check before you order saves you a return.

A 20-Meter Stable Link

A 20-meter (65 ft) stable wireless range gives the ulanzi j12 room to move — step back from the phone at an event, walk the street while it records, give a speaker the floor without hovering. And ≤25ms latency keeps audio locked to video, so lips stay in sync and no correction in post is needed. The range diagram above is an illustrative reconstruction of the two numbers that matter for wireless confidence — 20m of distance, 25ms of delay — both verified in the research notes. For interviews, events, and live streams, that combination means the mic never becomes the reason a take gets scrapped.

800mAh of Reserve

Each ulanzi j12 transmitter runs on its own built-in 80mAh battery — and when a shoot runs long, the earbud-style 800mAh charging case is the reserve: dock the transmitters between sessions and keep recording through the day. The case carries the two transmitters the way an earbud case carries earbuds — snap them in, close the lid, and they charge while you move to the next location. The power story is honest: transmitters carry their own cells, the case carries the reserve, and the Type-C receiver draws from the connected phone. No cable dangling from anyone’s shirt. For all-day event coverage, the routine is simple — record a session, dock the ulanzi j12 transmitters in the case between sessions, and grab them recharged for the next one — so the kit never sits idle waiting on a wall charger.

Headphone Monitoring

Plug earphones into the receiver and you hear your audio live while recording — that is headphone monitoring, and it is the difference between discovering a ruined take after the shoot and fixing it on the spot. The receiver carries the monitoring jack, so you can check levels and clarity in real time during interviews and streams. The card above shows the setup: receiver in, earphones in, record with confidence.

Inside the J12

Inside each transmitter: the omni-directional microphone capsule that picks up sound naturally from all directions, the 80mAh rechargeable battery, and the denoise module that powers the intelligent noise reduction — the hardware that filters background chatter and wind out of your voice. The x-ray render above is an illustrative reconstruction of the transmitter’s listed internals, per the manufacturer — not a photograph of disassembled hardware — but the architecture it shows is real: capsule, battery, denoise, in a pocket-sized body. And the whole transmitter weighs into a 69g system, built on an ABS body made for daily shooting.

Everything in the Kit

The ulanzi j12 kit is built around three pieces: the two wireless transmitters, the slim Type-C receiver, and the earbud-style charging case — shown above with callouts for each part. Nothing in the kit is decorative: the transmitters capture the voices, the receiver delivers them to the phone, and the case keeps both charged and protected between shoots. The infographic is an illustrative reconstruction of the verified kit hardware, not a packing photograph, but the architecture is exact: Transmitter ×2, Type-C receiver, charging case. Everything in the kit exists to serve one job: two voices into one Type-C Android phone, wirelessly, in one take.

The charging case itself, up close: both transmitters docked and ready to grab. The case is the system’s home base — charge, store, and carry the whole dual-mic kit in one pocket-sized unit, and flip it open when the shoot starts. Pair it with the 20-meter range and the denoise hardware, and the ulanzi j12 is a complete on-the-go interview setup.

Specifications

All figures are taken from the verified research notes. This page describes the dual-channel Type-C system in full — do not confuse it with the single-mic Ulanzi WM-10 for Android, the Lightning-variant Ulanzi WM-10 for iPhone, or the Ulanzi A30 and DCM-05 models.

A Shoot Day With Two Transmitters

Picture the day the ulanzi j12 was designed for. It starts with a street interview: two people, two transmitters, one Android phone on a small tripod. Both voices land in a single take — the questions and the answers at matched closeness — while the intelligent noise reduction pushes the street’s chatter and wind down under the conversation. There is no mic to pass back and forth, no second recording to align later, and headphone monitoring through the receiver lets you confirm the audio is clean before the interviewee walks away.

The middle of the day is movement. At an event or in a market, the 20-meter range lets the phone stay in one safe spot while the person wearing the transmitter walks the scene, and the ≤25ms latency means what you preview is what the video keeps — lips and words locked together. Between sessions, both transmitters go back into the earbud-style charging case, where the 800mAh reserve tops them up while you relocate. By evening, the same kit sits at a podcast desk for a two-host recording — the transmitters charged by the case through the day, the routine unchanged: plug the receiver in, and it pairs automatically.

Why Range and Latency Decide Whether a Take Survives

Two numbers on the ulanzi j12’s specification table decide more shoots than any other. The first is the 20-meter stable wireless range. Range is not really about distance records — it is about who controls the frame. With twenty meters of reach, the camera can sit where the shot looks best while the voice stays close-miked on the speaker’s collar, instead of the phone having to huddle wherever the audio works. Wide establishing shots, walk-and-talk segments, and demonstrations at arm’s length all come from that one allowance.

The second is the ≤25ms latency. Latency is the delay between a word being spoken and it arriving in the recording; when it grows, mouths and voices drift apart on video and someone has to fix it in post. At the J12’s verified figure, the delay is small enough that audio stays locked to video as recorded — what you hear through the monitoring earphones is what the viewer hears, in sync. Paired with omni-directional pickup, which captures the voice naturally from all directions, the system asks very little technique of the people wearing it: clip on, be heard from any angle, stay in sync.

Frequently Asked Questions

Is the ulanzi j12 really made for Android?

Yes — this listing is the Type-C Android version of the ulanzi j12. Its receiver plugs straight into a Type-C Android phone and pairs automatically, with no app or Bluetooth. It is not the iPhone/Lightning variant, and no iPhone compatibility is claimed — if your recorder is a Type-C Android phone, this is exactly the kit for it.

How is the ulanzi j12 different from the Ulanzi WM-10?

Different kits entirely. The Ulanzi WM-10 for Android is the single-mic clip-on option — one microphone, no charging case — while the ulanzi j12 is the dual-transmitter kit: two transmitters, a Type-C receiver, and the 800mAh earbud-style charging case. Buy this kit if you want two voices recorded at once; the WM-10 is the solo-mic alternative sold separately.

How is the ulanzi j12 different from the Ulanzi A30 and DCM-05?

They are different Ulanzi models with different designs — the A30 is the tiny lavalier model and the DCM-05 is a separate listing. This page describes only the ulanzi j12 dual wireless system with its Type-C receiver and 800mAh charging case; nothing from the sibling models is described or sold here.

Do both transmitters record at the same time?

Yes. The ulanzi j12 is a dual wireless system: both transmitters capture audio simultaneously and send it to the one Type-C receiver, so your Android phone records both voices in a single take. That is the point of the kit — no passing a single mic back and forth, no second track to sync in post.

Will the ulanzi j12 work with my Android phone?

It works with Type-C Android phones, but check two things first. Some phones — notably some OPPO and VIVO models — need OTG enabled before the receiver is recognized, and the product page lists Samsung S8/S9/S20-series phones and Google phones as incompatible. If your phone is a current Type-C Android model outside those exclusions, plug in the receiver and it pairs automatically.

What is the wireless range and latency of the ulanzi j12?

The ulanzi j12 reaches up to 20 meters (65 ft) of stable wireless transmission with ≤25ms latency. Twenty meters lets you step back from the phone while it records; the low latency keeps audio locked to video so lips stay in sync without correction in post. Both figures are from the verified research notes.

How long does the battery last?

Each transmitter carries a built-in 80mAh battery, and the earbud-style charging case holds an 800mAh reserve — dock the transmitters between sessions to keep them topped up through long shoots. The research notes do not state a rated runtime in hours, so this page makes no hours claim: the 80mAh/800mAh figures are the verified hardware, and the Type-C receiver draws its power from the connected phone.

Does the ulanzi j12 have noise reduction?

Yes — the research notes list intelligent noise reduction, which filters background chatter and wind so your voice stays clear. It helps at events, outdoors, and on busy streets where surrounding noise would otherwise swamp a phone’s built-in microphone. It does not make a noisy room silent, but it meaningfully separates voice from surroundings.

How does headphone monitoring work on the ulanzi j12?

Plug a pair of earphones into the receiver and you hear your audio live while recording. That lets you catch a problem — low levels, wind blasts, a loose transmitter — during the take instead of after it. Monitoring runs through the receiver itself, so it works whenever the system is recording.

What warranty does the ulanzi j12 come with?

This microphone system comes with a 7-day store warranty. If a warranty matters to you, confirm the terms with the store — hotline 09638054751, care@gadgetsuperb.com, or Messenger — before placing your order.

How long does delivery take, and what are the charges?

Inside Dhaka, delivery costs ৳70 and takes 1–3 working days; outside Dhaka, it costs ৳120 and takes 2–5 working days. These are estimates, not guarantees. Your order ships once you place a cash-on-delivery order.

What is the price of the ulanzi j12 in Bangladesh?

The current price is shown on the product page and can change during sales, so no figure is quoted here. Check the live Ulanzi J12 page on Gadget Superb for today’s price — that is what you pay in cash on delivery, plus the standard delivery fee.

What does the ≤25ms latency mean when I watch my video back?

It means the audio arrives almost exactly with the picture. Latency is the delay between a word leaving your mouth and the phone recording it; at the ulanzi j12’s verified ≤25ms, that gap is too small to notice, so lips and speech stay in sync with no correction needed in editing. It is one of the figures that makes the J12 practical for interviews and live-style shooting rather than just recording.

How should I charge and store the ulanzi j12 between shoots?

Dock the transmitters in the charging case — that is both the storage and the charging routine. Each transmitter carries its own built-in 80mAh battery, and the earbud-style case holds an 800mAh reserve that tops them up between sessions, so the kit lives in the case, charges in the case, and travels in the case. The Type-C receiver needs no charging of its own; it draws power from the connected phone.

Can I use the ulanzi j12 for live streaming?

Yes — live streams are one of the uses the system was made for. The receiver plugs into your Type-C Android phone and pairs automatically with no app and no Bluetooth, both voices from the two transmitters feed straight into the phone your stream runs on, and headphone monitoring through the receiver lets you hear your audio live while you broadcast, so a problem gets fixed on air instead of discovered afterward.
