Ulanzi A100 Wireless Lavalier Microphone

Your phone’s camera keeps getting better. Its built-in mic still hears the room. The Ulanzi A100 is the dual wireless lavalier system built for creators who need two clean voices on one take — a pair of featherlight 8.8g transmitters and one clip-on receiver, all living in a pocketable 800mAh charging case. The ulanzi a100 exists for one honest reason: interviews, podcasts, and two-person vlogs where a single mic always leaves someone’s voice thin and distant. If you have ever boosted a guest’s audio in editing until the room hiss rose with it, this is the fix — two mics at the source.

What it is, honestly. The ulanzi a100 ships as a dual-mic kit: two transmitters, each running about 5 hours on its 70mAh cell, talking over Bluetooth 5.3+EDR to one receiver with a back clip. The receiver runs about 24 hours per charge — longer than any shooting day — and the link reaches at least 20 meters with just 30ms of delay, so your audio stays in sync with your video. Three levels of built-in noise reduction push down streets, crowds, and café chatter, while the omni-directional capsules (20Hz–20kHz response, −38±2dB sensitivity) keep both voices natural from any angle. One-touch pairing means the kit is ready in seconds — no app, no settings hunt.

One thing to clear up before the details, because Ulanzi has a big mic family: this listing is the A100 — the dual-mic kit with the charging case. It is NOT the Ulanzi A200 (a different model), NOT the tiny Ulanzi A30 (sold on its own listing), NOT the Ulanzi WM-10 family, NOT the Ulanzi J12 dual kit (sold on its own listing), and NOT the Ulanzi DCM-05 (sold on its own listing). If you want two lavalier mics, one receiver, and a charging case that refills both mics twice over, the ulanzi a100 is this listing. Everything below describes this kit only.

Featherlight 8.8 Grams

The ulanzi a100’s headline number is its smallest: 8.8 grams per transmitter. At 43 × 18 × 18 mm, each mic is a slim ribbed stick that clips to a collar or lapel and stays put without dragging the fabric down — the feature card above says it plainly: clips on without dragging your collar. That matters for full-day shoots, because a mic you feel is a mic you fidget with on camera. A small LED indicator shows the transmitter’s state at a glance, and the back clip grips fabric securely.

Shoot All Day, Charge Twice Over

Each transmitter’s 70mAh cell runs about 5 hours per charge — a full morning of interviews or a long vlog day — while the receiver’s 70mAh cell runs about 24 hours, so the little black box on your phone or camera outlasts every shooting day you will ever have. Then there is the charging case: its 800mAh battery refills both transmitters more than twice over, so two days of heavy shooting happen without hunting for a wall socket. Everything refuels in about 1.5 hours. The battery card above states the headline without dressing: 5-hour mic, 800mAh case.

Three Levels of Quiet

Noise reduction is not a sticker on the ulanzi a100 — it is a switch with three settings. The DSP-based noise reduction steps from light cleanup to aggressive cutting, so you dial in exactly how much of the world to keep out: a quiet studio gets level one, a busy street gets all three. The omni-directional capsules keep speech natural at every level, with a ≥115dB maximum SPL that handles loud voices without distorting. For outdoor work, the kit ships with two furry windshields that slip over the transmitters and take the edge off wind. Between the three levels and the windshields, the ulanzi a100 treats noisy Bangladesh streets as a normal shooting location, not an exception.

Two Mics. One Take.

The flat-lay above is the whole kit, labeled piece by piece: two transmitters, the charging case, the receiver, and the furry windshields — that is everything the ulanzi a100 ships with, per the store’s own reference photos. Two mics means the interviewer and the guest both get a close, personal mic; no one shares, no one leans in, and no one’s voice is the room-mic afterthought in the mix. Both transmitters pair to the single receiver, which carries a back clip and status LEDs so you can check at a glance that both channels are live. Two voices, recorded equally well: that is the ulanzi a100’s entire job, and it does it with a kit that fits in a jacket pocket.

Twenty Meters of Bluetooth 5.3

The ulanzi a100 links its mics to the receiver over Bluetooth 5.3+EDR — not a proprietary 2.4 GHz radio, but the modern Bluetooth standard with enhanced data rate. The link holds to at least 20 meters in the open, with just 30ms of latency — low enough that lips and words stay locked together on video. One-touch pairing gets both transmitters connected in seconds, and the mono-channel 32kHz/16-bit audio path keeps voices crisp and intelligible. The infographic above is an illustrative reconstruction of that link: transmitter to receiver, 20 meters of air, nothing in between but signal.

Inside the A100

Small outside, busy inside. The x-ray render above is an illustrative reconstruction of the transmitter’s listed internals — not a photograph of disassembled hardware — but the architecture is real: the omni-directional capsule that captures your voice, the 70mAh cell that powers five hours of it, and the Bluetooth 5.3 module that carries it at least 20 meters to the receiver. The callouts mark the three parts that matter — capsule, battery, radio — packed into a body barely bigger than a matchstick. Every part exists for one job: your voice, clearly, into the receiver.

Clear Voice, Anywhere

The ulanzi a100 was built for the four jobs creators actually do: vlogging to camera, interviewing a guest on the street, recording a two-person podcast, and streaming from a desk. The promo hero above shows the kit as it travels — case open, both transmitters ready, receiver waiting — and the orange chip says the quiet part out loud: 3-level noise reduction, because “anywhere” includes Dhaka traffic. Two transmitters mean the host and the guest each get their own mic; the charging case means the kit survives a day of it; the 20-meter link means the camera can sit where the shot is good, not where the cable reaches.

Charge On The Go

The charging case is the ulanzi a100’s secret weapon. This is not a storage box with a cable hole — it is an 800mAh power bank shaped like a kit case: dock the transmitters in their molded slots and the case refills them, both at once. More than two full refills of both mics means a weekend of shooting without a charger in your bag. The flip-top lid and molded slots keep every piece — both transmitters and the receiver — in its own place, so nothing rattles loose in transit. The promo card above states it in four words: charge on the go.

The Little Black Receiver

The receiver is the quietest member of the ulanzi a100 kit and the one you will touch least. At 9.6 grams and 48 × 25 × 13 mm, it is a compact black unit with a back clip, status LEDs, and a USB connector — the macro detail above shows all three. Clip it to your phone rig, your camera, or your belt; the LEDs tell you both transmitters are linked without opening any app. Its 70mAh cell runs about 24 hours — effectively forever in a shooting day — and it refuels in about 1.5 hours alongside the transmitters. One receiver, two transmitters, no pairing menus after the first touch.

Specifications

All figures are taken from the verified research notes (live store page, 2026-10-14). Battery figures follow the store’s main verified spec — see the spec-conflict note in the publish instructions. This page describes the Ulanzi A100 dual-mic kit only — do not confuse it with the Ulanzi A200, A30, WM-10 family, J12, or DCM-05.

What the Audio Numbers Mean for Two Voices

Three rows of the specification table decide how the ulanzi a100 actually sounds, and they repay a plain-language translation. Start with sensitivity: −38±2dB is how eagerly the omni-directional capsules pick up sound, and in practice it means a guest speaking at normal conversational level — not projecting, not performing — registers clearly at collar distance. Quiet speakers are the failure mode of single phone mics; a capsule tuned this sensitive, sitting twenty centimetres from the mouth, hears them properly the first time.

At the other end sits the ≥115dB maximum SPL figure, which is the loudness ceiling before distortion. Market sellers calling out prices, a presenter raising their voice over a crowd, laughter peaking mid-interview — those moments clip and crackle on lesser capsules, and they are exactly what a high SPL ceiling exists to absorb. Between the sensitive floor and the high ceiling, the 20Hz–20kHz frequency response covers the full span of both voices, so neither speaker sounds thin, boxy, or cut off at the edges.

Finally, the audio path itself: 32kHz/16-bit, carried on a mono channel. Mono is the honest choice for speech work — both transmitters feed one shared track, so the interviewer and the guest arrive at matched presence with no stereo separation to rebalance in editing. What you hear in the finished video is two voices at the same closeness, on one clean channel, ready to post. For interviews, podcasts, and vlogs, that is not a limitation of the ulanzi a100; it is the design working as intended.

The Battery Maths of a Two-Mic Day

Add up the ulanzi a100’s battery figures and a picture emerges of how long the kit genuinely runs between wall sockets. Each transmitter works about 5 hours per charge. The 800mAh charging case then refills both transmitters more than twice over — so across a long shooting day, the pair of mics has roughly fifteen hours of recording in reserve before the case itself needs power. The receiver, meanwhile, runs about 24 hours per charge, which in practice means it is never the piece that ends your shoot.

Play that out over a real weekend. Friday’s interviews drain the transmitters halfway; docked in the case overnight, they come back full without ever meeting a charger. Saturday’s street vlog runs long — swap in the case’s refills and keep rolling. By Sunday, the first time the kit asks for a wall socket, everything refuels in about 1.5 hours: transmitters, receiver, and case alike, ready for the next round. The case’s molded slots keep each piece in its own place through all of it, so the kit that goes back in the jacket pocket is the same organised kit that came out.

That arithmetic is why the charging case is the centre of this system rather than an accessory. A dual-mic kit without it is two batteries to manage and a hard stop at hour five; the ulanzi a100 turns the same kit into a rotation — shoot, dock, refill, shoot — where the only real limit is how much footage you planned to capture.

Frequently Asked Questions

Is the ulanzi a100 really a dual-mic kit?

Yes. The ulanzi a100 ships with two transmitters and one receiver — that is the whole point of this listing. Both mics pair to the single receiver, so the interviewer and the guest each get a close, personal mic on the same take. The “Everything in the Kit” image above labels every piece: two transmitters, the charging case, the receiver, and two furry windshields.

How is the ulanzi a100 different from the Ulanzi A200?

The A200 is a different model, not a bigger or newer version of this kit. This page describes and sells the ulanzi a100 only — the dual-mic kit with the 800mAh charging case, Bluetooth 5.3, and 3-level noise reduction.

How is it different from the Ulanzi J12 or DCM-05?

Both are separate listings in the same store. The Ulanzi J12 is another dual-transmitter kit with its own design and receiver style, and the Ulanzi DCM-05 is yet another distinct model — neither is the ulanzi a100. This listing’s kit — slim ribbed 8.8g transmitters, back-clip receiver, 800mAh charging case — is unique to the A100. Match the photos and the spec table to what you want before ordering.

How long does the ulanzi a100 battery last?

Each transmitter runs about 5 hours on its 70mAh cell — a full shooting session. The receiver runs about 24 hours on its 70mAh cell, far longer than any single day of shooting. The 800mAh charging case refills both transmitters more than twice over, and everything refuels in about 1.5 hours.

What is the wireless range, and is there delay?

The ulanzi a100 holds its Bluetooth 5.3+EDR link to at least 20 meters in the open, with just 30ms of latency — low enough that lips and words stay in sync on video. Like all wireless systems, walls and heavy radio interference shorten real-world range, so keep a clear line of sight for the longest takes. Pairing is one-touch, so both mics connect in seconds.

What does the 3-level noise reduction actually do?

The built-in DSP noise reduction has three strength levels, so you choose how much of the world to keep out: light cleanup for quiet rooms, stronger settings for streets and crowds. The omni-directional capsules keep voices natural at every level, and the two included furry windshields cut wind noise outdoors. It will not erase a construction site, but it meaningfully lifts speech out of everyday noise.

How light is the transmitter? Will it drag my collar down?

Each transmitter weighs 8.8 grams and measures 43 × 18 × 18 mm — genuinely featherlight. It clips to a collar or lapel and stays put without pulling the fabric down, even through a full day of shooting. The feature card above says it plainly: clips on without dragging your collar.

What comes in the box?

The ulanzi a100 kit includes two wireless transmitters, one receiver with a back clip, the 800mAh charging case, and two furry windshields — the full set shown in the “Everything in the Kit” image above. That is the complete dual-mic system: two voices, one receiver, and the case that keeps them charged and organized.

Do I need an app to use the ulanzi a100?

No. The kit uses one-touch pairing — power on the transmitters and the receiver and they link in seconds, with the receiver’s status LEDs confirming both channels are live. There is no app to install and no settings menu to configure. Clip on the mics, check the LEDs, and record.

What warranty does the ulanzi a100 come with?

The ulanzi a100 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. Cash on delivery is available across Bangladesh — you pay the courier in cash when the parcel arrives, and Gadget Superb never asks for advance payment, card details, OTPs, or mobile-banking PINs.

What is the price of the ulanzi a100 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 A100 page on Gadget Superb for today’s price — that is what you pay in cash on delivery, plus the standard delivery fee.

How much recording time do I get before the kit needs a wall socket?

More than a shooting day, counted honestly. Each ulanzi a100 transmitter runs about 5 hours per charge, and the 800mAh charging case refills both transmitters more than twice over, so the pair carries roughly fifteen hours of recording in reserve. The receiver runs about 24 hours on its own charge. When everything finally does need power, transmitters, receiver, and case each refuel in about 1.5 hours.

Both voices record onto one track — is that a problem for editing?

No — for speech, it is usually the simpler outcome. The ulanzi a100 carries both transmitters on a single mono channel at 32kHz/16-bit, so the interviewer and the guest land on one track at matched closeness, with no stereo separation to rebalance and no second track to sync. You trim, level, and post. Creators who need each voice on its own separate track are the exception; for interviews, podcasts, and two-person vlogs, one clean shared track is the workflow most people actually want.

How do I look after the furry windshields and the case?

Both ask for very little. The furry windshields slip over the transmitters for outdoor work; between shoots, keep them dry and store them with the kit rather than loose in a bag, so the fur stays fluffy instead of crushed. The charging case does the rest of the organising — its molded slots hold both transmitters and the receiver in their own places, so docking the pieces at the end of the day is both the storage routine and the charging routine in one motion.
