Ulanzi A30 Wireless Lavalier Tiny Microphone

The mic your audience never sees is the mic that wins. The ulanzi a30 is Ulanzi’s tiniest wireless lavalier — an 11-gram, bean-sized transmitter that clips to a collar or lapel and practically vanishes on camera, while an omnidirectional condenser capsule captures your voice with an 83dB signal-to-noise ratio. The ulanzi a30 pairs that discreet form factor with a stable 2.4GHz wireless link: up to 50 metres line-of-sight, around 20ms latency, and one-touch pairing with no app and no setup.

Creators buy wireless mics for freedom, then lose the footage to a bulky visible transmitter or a dead battery. The ulanzi a30 answers both complaints at once. Each transmitter weighs 11 grams, runs about 5 hours on its own battery, and drops back into a charging case that pushes total runtime up to 20 hours. The receiver plugs straight into smartphones, cameras, and laptops over Type-C, Lightning, or 3.5mm TRS — plug-and-play recording, no drivers, no adapters to hunt for.

One honest framing before the details: the store’s product photography shows the receiver with a Lightning connector, while the listing claims Type-C, Lightning, and 3.5mm TRS compatibility. Gadget Superb lists wide compatibility, but the physical connector on the receiver in your box determines how it plugs into your device — confirm the receiver variant with the store before ordering if that matters to your setup. Everything below comes from the verified research notes; nothing is guessed.

Invisible on Camera: the 11g Tiny Design

The signature of the ulanzi a30 is its size. Each transmitter weighs just 11 grams — lighter than most clip-on lavaliers by a wide margin — and the bean-sized, matte-black body sits flat against fabric so it does not read as “a mic” in the frame. On-camera talent who refuse to wear a visible transmitter finally get one that does not need hiding, cropping, or an apology in the comments.

Wearing it is equally discreet. A white magnetic back plate pairs with a clip, so the ulanzi a30 can be clipped to a collar, slipped inside a shirt placket, or held in place magnetically through light fabric — no wardrobe damage, no visible bulk, no wardrobe changes between takes. For interviews, vlogs, and short-form content, the microphone simply stops being a prop in your own shot.

Clear, Natural Voice: 83dB SNR Condenser Capture

Tiny means nothing if the audio is thin. The ulanzi a30 uses an omnidirectional condenser capsule rated at −42±3dB sensitivity with an 83dB signal-to-noise ratio, capturing 48kHz/16-bit audio across a 50Hz–15kHz frequency response. The result is clear, natural voice capture — the kind of clean dialogue track that survives YouTube compression, Instagram reels, and client review without sounding like a phone call.

The omnidirectional pattern is a deliberate choice for creators. You do not need to aim it, angle it, or re-mount it mid-shoot: the ulanzi a30 picks up your voice evenly wherever you turn your head, which is exactly what you want on a run-and-gun interview or a walking vlog. The receiver’s onboard noise-reduction button gives you one-press help when the environment turns noisy — a street interview, a busy café, a windy rooftop.

Fifty Metres of Stable 2.4GHz Freedom

The ulanzi a30 transmits on a stable 2.4GHz link with a rated range of up to 50 metres in clear line-of-sight, dropping to 30 metres when walls and obstacles stand between the transmitter and receiver. That is a full studio, a house, or a stage wing of room to move — enough for wide B-roll walks, property tours, and multi-person interviews without a cable tethering the talent to the camera.

Latency sits at around 20ms, which keeps lip-sync tight on video — dialogue stays glued to the speaker’s mouth with no drift to fix in the edit. Pairing is one-touch: power the transmitter and receiver, tap to link, and the ulanzi a30 is ready before your camera finishes booting. The range infographic above is an illustrative reconstruction of the verified 50-metre link — not a field measurement — and the figures themselves come straight from the manufacturer’s specifications.

All-Day Power: 5-Hour Mic, 20-Hour Case

A dead mic ends a shoot faster than bad light. Each ulanzi a30 transmitter carries a 100mAh battery good for about 5 hours of continuous recording, and recharges in roughly 1.5 hours. Dock both transmitters in the charging case and total runtime stretches to up to 20 hours — enough for a full wedding day, a multi-location vlog, or a week of short daily recordings without hunting for a socket.

The case itself recharges in about 3 hours and doubles as the kit’s storage: transmitters and receiver each get a molded slot, so the whole system travels as one pocketable unit instead of three loose pieces rattling in a bag. For creators who shoot all day on location, the ulanzi a30 turns battery anxiety into a non-issue.

One Mic, Every Device

The ulanzi a30 refuses to care what you shoot on. The receiver connects to smartphones, cameras, and laptops through Type-C, Lightning, or 3.5mm TRS, and the system is plug-and-play: no app to install, no drivers to configure, no firmware ritual before a shoot. It works across Android, iOS, Windows, Linux, and HarmonyOS devices.

The ulanzi a30 receiver carries two physical buttons with LED indicators — one for muting the transmitters, one for toggling noise reduction — so you can silence the mic between takes or cut background hiss without touching the camera. One caveat worth repeating: the listing claims three connector types, and the store’s own gallery photos show a Lightning receiver, so the connector on the unit in your box decides your cable path. If you shoot on a specific phone or camera, message the store and confirm the receiver variant before you order.

Inside the A30

Inside the 11-gram shell, the ulanzi a30 packs an omnidirectional capsule, a 100mAh battery, and a noise-processing board — the full signal chain of a wireless mic, compressed into a body smaller than most key fobs. The white magnetic back plate and clip mounting are part of the transmitter itself, so there are no separate mounts to lose between shoots.

The x-ray render above is an illustrative reconstruction of the manufacturer’s listed internals — the omni capsule, 100mAh battery, and noise processor — not a photograph of disassembled hardware. The figures it labels come from the verified specifications, and the footnote on the image states the reconstruction plainly.

Specifications

All figures are taken from the verified research notes and the manufacturer’s published specifications. Exact dimensions, case battery capacity in mAh, and charging-cable contents are not published in the research notes and are therefore omitted rather than estimated.

What’s in the Box

The box contains the ulanzi a30 kit: two wireless transmitters, one receiver, and the charging case with molded slots for all three — plus the magnetic back plates that pair with the transmitter clips. The kit infographic above is an illustrative reconstruction of the verified box contents — not a packing photograph.

Two honest exclusions. First, the research notes do not list a charging cable in the box — if one is not included, you will charge the case with your own USB cable, so confirm with the store if that matters to you. Second, as flagged above, the receiver’s connector variant (Type-C vs Lightning) is worth confirming with the store before ordering, since the store’s gallery photos show a Lightning receiver.

What 83dB SNR and 48kHz/16-Bit Mean for Your Voice

The audio numbers on the ulanzi a30 reward a plain-language translation. The 83dB signal-to-noise ratio is the cleanliness figure: your voice sits far above the microphone’s own electronic noise floor, so the silent gaps between sentences are actually silent — no hiss bed under the dialogue. That matters more after upload than before it, because platform compression is unkind to noisy recordings; a track that starts clean survives YouTube, reels, and client review sounding like a voice, not a phone call.

Sensitivity of −42±3dB and a 50Hz–15kHz frequency response cover the working range of speech — the body of the voice at the bottom, the consonant clarity at the top — captured at 48kHz/16-bit. And because the capsule is omnidirectional, the ulanzi a30 picks your voice up evenly wherever you turn your head: no aiming it, no angling it, no re-mounting mid-shoot when an interview turns into a walk. For run-and-gun recording, that forgiveness is the specification you feel most.

Shoot Day With the A30: A Simple Routine

The routine starts the night before. The charging case recharges in about 3 hours and each transmitter in roughly 1.5 hours, so a kit plugged in overnight wakes up with about 5 hours in each transmitter and up to 20 hours of total runtime in the system. Everything travels in the case’s molded slots — two transmitters, the receiver, the magnetic back plates — as one pocketable unit instead of three loose pieces rattling in a bag.

On location, setup is a non-event: power the transmitter and receiver, tap to pair, and you are recording before the camera finishes booting. Run both transmitters for a host-plus-guest interview, and work the receiver’s two buttons between takes — mute the transmitters while the crew resets, toggle the noise reduction when the location turns into a street, a busy café, or a windy rooftop. The ulanzi a30 keeps every one of those decisions on the hardware, with LED indicators, instead of in an app menu.

Between locations, dock the transmitters back in the case. The top-ups stretch across the day toward that 20-hour total, which is how the kit covers a full wedding day or a multi-location vlog without hunting for a socket. At the end of the shoot, everything returns to its molded slot — the same pocketable case, ready for the next morning’s charge.

Frequently Asked Questions

Is this the original Ulanzi A30?

This listing is for this model as catalogued by Gadget Superb under the Ulanzi brand. The store does not claim official-distributor status for any brand it carries. If authenticity documentation matters to you, message the store on Messenger or email care@gadgetsuperb.com before ordering and they will clarify what they can share.

How tiny is the ulanzi a30 transmitter, really?

Each transmitter weighs 11 grams — about the weight of two coins — in a bean-sized matte-black body that sits almost invisibly on a collar or lapel. A white magnetic back plate pairs with a clip, so it can be clipped, slipped inside a shirt placket, or held magnetically through light fabric without wardrobe damage.

How many transmitters come in the box?

Two transmitters and one receiver, plus the charging case. That covers two-person interviews, host-plus-guest setups, or a backup transmitter on solo shoots — both transmitters pair to the single receiver with one touch.

How far can I walk from my camera or phone?

Up to 50 metres in clear line-of-sight, and 30 metres when walls or obstacles stand between the transmitter and the receiver. Keep the receiver’s path to the transmitter as clear as you can on long walks, and expect the range to shrink in crowded or obstructed environments.

What is the audio quality of the ulanzi a30?

The ulanzi a30 uses an omnidirectional condenser capsule (−42±3dB sensitivity) with an 83dB signal-to-noise ratio, capturing 48kHz/16-bit audio across 50Hz–15kHz. Voice comes through clear and natural, and the receiver’s noise-reduction button helps in noisy environments like streets and cafés.

How long does the battery last?

Each ulanzi a30 transmitter runs about 5 hours on its 100mAh battery and recharges in roughly 1.5 hours. Docked in the charging case, total runtime reaches up to 20 hours; the case itself recharges in about 3 hours. That is a full shoot day without hunting for a socket.

Which devices does the ulanzi a30 work with?

Smartphones, cameras, and laptops across Android, iOS, Windows, Linux, and HarmonyOS. The receiver connects over Type-C, Lightning, or 3.5mm TRS, and the system is plug-and-play with no app and no drivers — plug it in, pair with one touch, and record.

Which receiver connector will I actually get — Type-C or Lightning?

The listing claims Type-C, Lightning, and 3.5mm TRS compatibility, but the store’s own gallery photos show the receiver with a Lightning connector. The connector on the unit in your box decides your cable path, so if you shoot on a specific phone or camera, confirm the receiver variant with the store — hotline 09638054751 or Messenger — before ordering.

What exactly is in the box — and what is not?

The verified kit is two transmitters, one receiver, the charging case with molded slots, and the magnetic back plates. A charging cable is not listed in the research notes, so confirm with the store whether one is included or plan to use your own USB cable to charge the case.

Does the ulanzi a30 come with a warranty?

This microphone carries 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 — pay the courier in cash when the parcel arrives.

What is the price of the ulanzi a30 in Bangladesh, and what is the return policy?

The current price is shown on the product page and can change during sales, so no figure is quoted here. Check the live Ulanzi A30 page on Gadget Superb for today’s price — that is what you pay in cash on delivery, plus the standard delivery fee. Every Gadget Superb product carries 7-day easy returns: keep the kit in original condition with box and accessories, and start a return with your order number via hotline, email, or Messenger.

Will the ≈20ms latency cause lip-sync problems in my videos?

No. Latency on the ulanzi a30 sits at around 20ms, which keeps dialogue glued to the speaker’s mouth on video — there is no drift to correct in the edit. It is one of the quiet advantages of the stable 2.4GHz link: the audio arrives with the picture, so interviews, vlogs, and short-form clips cut together the way they were shot.

How should I wear the ulanzi a30 for the cleanest voice?

Clip it to a collar or lapel, slip it inside a shirt placket, or hold it in place magnetically through light fabric with the white magnetic back plate — all three are built into the transmitter, and at 11 grams none of them pulls at clothing. Because the capsule is omnidirectional, it picks your voice up evenly wherever you turn your head, so there is no precise angle to maintain: wear it where it looks cleanest on camera and let the pickup pattern do the rest.

Can I mute the ulanzi a30 without touching the camera?

Yes. The receiver carries two physical buttons with LED indicators — one mutes the transmitters, the other toggles noise reduction — so you can silence the mic between takes or cut background hiss from the camera position, without touching the camera or opening an app. It is the control you reach for constantly on interview and event shoots, and the A30 keeps it on the hardware where it belongs.
