Acefast R2 Wireless Lavalier Microphone – Dual Mic

Your phone shoots great video. Its built-in microphone is the weak link — especially when there are two of you talking. The Acefast R2 is the dual-transmitter wireless lavalier system made for creators who want interview-grade audio without wires, apps, or complicated setup: the acefast r2 ships with two tiny transmitters that record at the same time, so interviews, two-host podcasts, and vlogs with a guest get clean voice from both people. The receiver plugs straight into your phone’s USB-C port and pairs automatically in about one second.

What it is, honestly. The acefast r2 is a 2× TX + 1× RX wireless system on the 2402–2480 MHz band: each 360° omnidirectional transmitter captures voice clearly from any angle, a deep noise-reduction mode cuts through street noise, crowds, and wind, and roughly 30ms of ultra-low latency keeps lips and voice locked in sync. Each mic runs up to 4 hours on its 60 mAh cell, and the pocketable 300 mAh charging case stretches total recording time to 20 hours — a full day of shooting — with a 10-minute quick charge buying you another hour when you are in a rush.

One distinction before the details: this listing is the ACEFAST R2 dual-mic kit — two transmitters, a USB-C receiver, and a charging case — and it is NOT the Ulanzi WM-10 family, NOT the Ulanzi J12 dual kit, and NOT the Hoco L15/L21/L22 wireless mics, all sold on their own listings. It is also strictly the USB-C version: the receiver plugs into USB-C phones and tablets, and it will not fit a Lightning-port iPhone. If your phone charges over USB-C, this is your mic.

Two Mics, Zero Fuss

The acefast r2 leads with the feature that matters most: two transmitters, recording at once. One mic for you, one for your guest: both voices captured cleanly at the source instead of one person shouting toward the phone. The triangle arrangement above shows the whole kit: two TX units with foam windscreens and green LED dots, plus the USB-C receiver that carries both voices into your phone. For interviews, duets, two-host podcasts, and street vlogs with a partner, it turns a solo setup into a two-person production with zero extra gear.

20 Hours in the Case

Battery anxiety is the creator’s oldest enemy, and the acefast r2 answers it with a case that works like a power bank for your mics. Each 60 mAh transmitter runs up to 4 hours per charge, and every time a mic docks into the 300 mAh charging case it tops back up — stretching total recording time to 20 hours. The battery card above states it plainly: 4 hours per mic, 20 hours total with the charging case. Charging is over USB-C at 5V/0.35A, a full charge of mic and case takes about an hour, and the 10-minute quick charge buys you another hour of recording when you are in a rush. The green LEDs glow while the mics dock, so you always know it is charging.

15-Meter Freedom

Wired lavs tether you to the camera; the acefast r2 sets you free. The 2402–2480 MHz wireless link holds a stable connection up to 15 meters — enough to walk through a scene, demo a product across the room, or interview a guest while the phone stays on its tripod. The range card above is the idea in one frame: the creator walks, the phone stays put, both voices carried cleanly. Like every 2.4 GHz-band system, thick walls and heavy interference shorten that in practice — but across the room, the studio, or the street, you stay untethered.

Every Piece, Ready

The flat-lay above is an illustrative reconstruction of the complete acefast r2 system, and it doubles as your packing checklist: TX Unit ×2 — two transmitters with windscreens and back clips; the USB-C Receiver — the plug that feeds your phone; the Charging Case — the 20-hour dock; and the USB Cable for recharging. Nothing here is decorative — every piece earns its place, and every piece is in the box. Open the case, plug in the receiver, and the system is whole: no app, no manual pairing.

Sound From Every Side

You do not aim an omnidirectional mic — you clip it on and talk. The acefast r2’s 360° pickup ring, shown as an illustrative reconstruction above, captures your voice clearly from any direction: straight on, turned slightly away, laughing, leaning in. That is what makes a lavalier forgiving for real creators — no sweet spot to maintain, no “speak into the mic” coaching for your guest. The green LED status dot sits visible on the oval face so you can confirm at a glance that the mic is paired and rolling. For interviews and two-person content, that forgiveness is the difference between natural conversation and stiff, mic-aware performances.

Inside the Transmitter

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 omnidirectional capsule that captures your voice, the wireless chipset that carries it 15 meters to the receiver, the rechargeable battery behind 4 hours per charge, and the LED status circuit behind the green dot. Four parts, one job: your voice, clearly, from wherever you stand.

Inside the Receiver

The receiver is the quiet half — and the x-ray above, an illustrative reconstruction, shows why it just works. The USB-C connector plugs into your phone; the signal processor turns the wireless feed into audio your camera app understands; the pairing circuit is why the mics connect in about a second; and the LED status circuit confirms the link is live. No battery to charge on this side — the receiver draws what it needs from the connected phone. One job, no learning curve: plug it in, and your phone has two wireless mics.

The Dual-Mic Hero

This is the acefast r2 as it ships: two transmitters, one USB-C receiver, ready to record. The dual-mic badge is the whole pitch — most budget wireless mics in this price band ship a single transmitter and leave your guest shouting at the phone; the acefast r2 gives both speakers their own close mic. At 48 grams total for the kit, it travels in a pocket and sets up in under a minute. If you shoot interviews, duets, two-host podcasts, or street content with a partner — and your phone charges over USB-C — this is the cheapest honest path to two-person audio that sounds recorded on purpose.

Everything in the Box

No mystery, no missing pieces. The flat-lay above shows the verified box contents, chip by chip: 2× TX Units — two transmitters with windscreens and back clips; the USB-C Receiver — the plug that feeds your phone; the Charging Case — the 20-hour dock; the Windscreens; and the Cable — USB-A to USB-C for recharging, plus the user manual. The green chips mark exactly what is in the box — no accessory is claimed that you will not find when you open it.

Specifications

All figures are taken from the verified research notes for the Acefast R2 dual-mic USB-C system — not to be confused with single-mic wireless kits or Lightning-receiver models.

What 71 × 51 × 26 Millimetres and 48 Grams Actually Mean

Two figures sit in the specifications table that most readers skip, and together they describe the acefast r2’s real portability. The dimensions — 71 × 51 × 26 mm — are the whole system, case included: two transmitters, the USB-C receiver, and the charging case that powers them, packed into a box smaller than a deck of cards is wide. The weight — 48 grams total — is the number that makes it a pocket kit rather than a bag kit. There is no separate pouch of parts to remember, because the case is the kit: open it and every piece is in its place.

That compactness changes when the kit gets used. A system that lives in a jacket pocket is a system that is present for the unplanned interview, the street encounter, the guest who agrees to talk for five minutes if you start now. Setup supports the same speed: the mics pair automatically in about a second out of the case, the receiver plugs straight into the phone’s USB-C port, and there is no app to open. From pocket to recording is under a minute, and the acefast r2 asks for nothing to be charged, carried, or configured separately along the way.

Even recharging stays inside the same small footprint. The kit charges over USB-C at 5V/0.35A using the included USB-A to USB-C cable — the same class of USB charging every phone charger, laptop port, and power bank already provides — and a full charge of mic and case takes about an hour. Small in the pocket, quick on the charger, whole in one case: the dimensions in the table are the reason the dual-mic setup is a habit rather than an event.

Two Voices, One Conversation: How a Dual-Mic Take Actually Flows

Watch a good two-person take happen with the acefast r2 and the choreography is the point. The phone goes on its tripod where the framing is right — up to 15 meters away if the shot wants it. One transmitter clips to your guest, one to you. A glance at the green LED dots confirms both are paired and rolling, and then the conversation simply starts, at natural distance, with nobody leaning toward a phone or performing for a microphone.

The 360° omnidirectional pickup is what makes that naturalness possible. Your guest can turn, laugh, gesture, and answer at whatever angle the conversation takes; the capsule hears the voice clearly from any side, so there is no coaching — no “stay facing the mic” — breaking the flow. The deep noise-reduction mode works underneath, holding street noise, crowds, and wind down so the surroundings stay context instead of competition.

And when the take ends, the workflow closes as neatly as it opened. Transmitters dock back into the case — the green LEDs glow while they charge — and the 20-hour total recording reserve quietly rebuilds for the next conversation. Two-host podcasts record the same way, episode after episode: same case, same clips, same one-second pairing. The acefast r2 does not add a production step to two-person content; it removes the one that used to make both voices a compromise.

Frequently Asked Questions

Is the acefast r2 a single mic or a dual-mic kit?

It is a dual-mic kit: two wireless transmitters, one USB-C receiver, and a charging case — both transmitters record at the same time, so two speakers are covered. One transmitter also works fine on its own for solo recording; but this listing is the two-mic system, not a single-mic variant.

Will the acefast r2 work with my phone?

If your phone charges over USB-C, yes — the acefast r2’s receiver plugs straight into the USB-C port and pairs with the mics in about a second, with no app needed. USB-C tablets work the same way. A Lightning-port iPhone will not fit this receiver — the plug is USB-C only, so check your charging port before ordering.

How is the Acefast R2 different from the Ulanzi J12 or Hoco L21?

Different models, different brands, different listings. This is Acefast’s dual-mic kit — two transmitters, a USB-C receiver, and a 20-hour charging case — while the Ulanzi J12 is Ulanzi’s own dual kit and the Hoco L21 family are single-mic systems sold separately. Nothing about those models is described or sold here; compare the listings side by side.

What does the noise-reduction mode do?

The deep noise-reduction mode cuts through environmental noise — street noise, crowds, wind — so your voice stays front and center in the recording. It is there for real-world shooting — markets, roadsides, busy events — where the location is never silent. The capsule still captures naturally; the processing keeps the surroundings from swallowing your words.

What is the wireless range of the acefast r2?

The acefast r2 holds a stable wireless connection up to about 15 meters on its 2402–2480 MHz link — enough to walk through a scene while your phone stays on its tripod. Thick walls and heavy interference shorten that in practice, so keep a clear line of sight for the longest takes.

How long does the battery last, and what is the 10-minute quick charge?

Each 60 mAh transmitter runs up to 4 hours per charge; docking the mics in the 300 mAh case stretches total recording to 20 hours. A full charge over USB-C takes about an hour, and the 10-minute quick charge buys you another hour when you are in a rush.

Why does ~30ms latency matter for my videos?

Latency is the delay between your lips moving and the audio reaching the video — at roughly 30ms, the two stay locked together, so there is no visible drift and nothing to re-sync in the edit. Cheap wireless systems with high latency leave you nudging audio tracks after every take; this one is built to stay in sync from the first take.

What is the voice changer on the acefast r2?

The acefast r2 has a built-in voice changer with Female and Male voice modes, switched with one press of the mic’s side function button — a creative extra for skits, characters, and playful content. It is a fun feature, not a professional tool: record your serious interviews in the normal voice mode and save the changer for the bits that are meant to be funny.

What is in the box?

The box carries 2× Acefast R2 wireless microphones with foam windscreens and back clips, 1× wireless receiver (USB-C), 1× portable charging case, 1× USB-A to USB-C charging cable, and 1× user manual — the complete kit, ready to record.

What warranty does the acefast r2 come with?

This microphone kit 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 acefast r2 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 Acefast R2 page on Gadget Superb for today’s price — that is what you pay in cash on delivery, plus the standard delivery fee.

Does the receiver have its own battery to charge?

No — the receiver is the one piece of the acefast r2 you never charge. It plugs into your phone’s USB-C port and draws the small amount of power it needs from the phone itself, which is why there is no battery figure for it in the specifications. The pieces with batteries are the two transmitters (60 mAh each, up to 4 hours) and the charging case (300 mAh, stretching total recording to 20 hours).

How do I know the mics are paired, rolling, and charging?

The green LED on each transmitter tells you all three. A lit green status dot on the oval face confirms the mic is paired and rolling before you start talking — worth a glance at your guest’s collar as well as your own. Docked in the charging case, the green LEDs glow while the mics charge, so the case itself reports that the 20-hour reserve is rebuilding. No app screen or menu is involved in any of it.

How do I clean and store the kit between shoots?

Store everything in the charging case — that is what it is for. The transmitters dock in their places, the receiver and cable travel with them, and the foam windscreens stay on the mics, protected instead of loose in a bag. Keep the windscreens dry and brush dust off them gently; wipe the glossy transmitter bodies with a soft, dry cloth. Stored that way, the acefast r2 comes out of the case in the same ready state it went in: paired in about a second, charged, and complete.
