How to Choose a Wireless Mic for Your iPhone or Android Phone

A wireless mic is one of the easiest ways to make phone videos sound better, but not every mic works with every phone or every app. Before you compare sound or battery life, check the few things that decide whether a mic will work for you at all. This guide covers what to check, what to compare between kits, and how to match a kit to the way you record.

Clip-on mics keep your hands free, while handheld mics suit interviews where the mic moves between people. For more on choosing between the two, see Clip-On vs Handheld Mic.

iPhone 15 and later use USB-C, while iPhone 14 and earlier use Lightning. Most Android phones use USB-C. Many kits are sold in USB-C and Lightning versions, and a USB-C receiver works with both USB-C iPhones and Android phones.

Note: Many USB-C and Lightning adapters don't carry mic audio, so choose a receiver that matches your phone’s port.

Most wireless mic kits have two parts: a transmitter you wear or hold, and a small receiver that plugs into your phone. The transmitter sends audio to the receiver over its own wireless link, and your phone treats the receiver like a wired mic. That’s why receiver kits work in most apps that accept an external mic.

Some mics skip the receiver and connect over Bluetooth instead. That’s convenient, but many only work inside the maker’s own app, and sound quality is often lower than through a receiver.

On iPhone, most camera and recording apps pick up a plugged-in mic. On Android, support in the built-in camera app varies by phone, and some models need a third-party camera app to use an external mic. Whatever you buy, test it in the app you’ll actually use.

One transmitter covers solo content. For interviews or co-hosted videos, you’ll want one transmitter per person. Some kits include two in the box, while others let you add a second later.

With two mics, check how the kit sends audio to your phone:

• Mixed: Both voices are combined into one track. This is the simplest option if you post straight from your phone.
• Split: Each voice goes to its own channel, so you can balance them when editing. If you post a split recording without editing, each voice can end up in only one ear.

Our guide to recording two people on one phone walks through both setups.

Most current kits record voice at similar quality, so compare the features around the mic.

• Adjustable noise cancellation: Noise cancellation reduces background sound, but strong settings can make your voice sound thin. Look for levels you can choose, plus a way to switch it off in quiet rooms.
• Windscreens in the box: Outdoors, a furry windscreen blocks wind before it reaches the mic. Noise cancellation can't remove strong wind on its own, and our guide to reducing wind noise when filming outdoors covers what else helps.
• Auto gain with a manual option: Gain sets how loud your voice comes through. Automatic gain control (AGC), often labeled Auto Gain, adjusts it as you speak louder or softer, which suits most mobile recording. In places with constant background noise, AGC can raise the noise along with your voice, so a manual setting is useful. When to switch between automatic and manual gain depends on the room.
• Built-in processing: Many kits clean up audio on the device itself, with low-cut filters and limiters that catch sudden loud peaks. A small chip called a digital signal processor (DSP) does this work inside the mic.
• Battery per charge and in total: Check both the runtime per charge and the total with the charging case or handle. Advertised figures are best-case numbers, so leave some margin.
• Charge-through: The receiver takes your phone’s only port, so a charge-through port lets you power your phone while you record. For long livestreams, check how much power it delivers. A low-wattage port may only slow the battery drain.
• Receiver fit: Thick phone cases can stop a receiver from plugging in fully. Compare the receiver’s shape with your case, or plan to take the case off.
• Realistic range: Advertised range assumes nothing is in the way. Your body, a pocket, or a crowd shortens it, so look for a steady signal at conversational distance rather than the biggest number on the box.
• Water resistance: If you often shoot in rain or near water, check whether the kit has an IP rating. Many don’t.
• Backup recording: Some transmitters save a copy of your audio on the device, sometimes in 32-bit float, a format that records loud peaks without clipping so you can turn them down in editing. That’s useful for interviews you can’t repeat, but you’ll need to move the files to an editor and sync them yourself.

If you mostly record solo clips and post them from your phone, an entry-level kit with a matching receiver, windscreens, and adjustable noise cancellation covers what you need. Spending more makes sense when you need backup recording, more transmitters, or outputs for a camera.

With Wave Go, you can clip the transmitter to your shirt or dock it in the Smart Handle for a handheld interview mic, all through one USB-C receiver. Audio travels to the receiver over a dedicated 2.4 GHz connection, and Bluetooth is used only for the free Wave Go app.

Wave Go handles your sound automatically:

• EQ Shift adjusts your tone for clip-on or handheld use.
• Auto Gain keeps your levels steady.
• A low-cut filter and dynamic range control run at all times.

In the Wave Go app, you can switch to manual gain or choose a noise cancellation level (Off, Low, Medium, or High).

For power, the transmitter runs about 8 hours per charge and up to 48 hours in total with the Smart Handle. The receiver’s charge-through port helps power your phone while you record.

Wave Go is a good fit if you:

• Record on a USB-C phone, tablet, or computer
• Record solo, or two people with a second Wave Go Transmitter (sold separately)
• Post straight from your phone
• Want one kit that covers clip-on and handheld recording

Another mic may suit you better if you:

• Use a Lightning iPhone, or record to a DSLR or mirrorless camera
• Need a separate track for each speaker, since two transmitters are mixed into a single mono signal
• Need an onboard backup recording
• Record three or more people
• Often shoot in the rain, since Wave Go has no water or dust resistance rating

Start with your phone’s port and the app you record in, then choose the number of mics and the features that match how you shoot. Once you’ve picked a mic, our tips for recording better audio on your phone cover placement and setup.
