If you’ve got a USB-C iPhone, like the iPhone 15, 16, or 17, or an Android phone, recording high-quality audio just got way easier. USB C wireless microphone lets you skip adapters and messy cables: just plug in, hit record, and you’re good to go.
In this post, we’re looking at two common types. One has a receiver with a built-in USB-C plug, so you can connect it straight to your iPhone. The other features a receiver with a USB-C port and includes a USB-C cable in the package, giving you flexible connection options.
Here are 3 top picks after testing dozens of options:
- SYNCO Smic
- SYNCO G2(A2)
- SYNCO G3 Pro
Introduction
Before we jump in, here are the main things we looked at when testing USB-C wireless microphones with smartphones:
👉 Sound Quality: How clear and natural does it capture voices, even when you’re moving around or outdoors?
👉 Connection Reliability: Does the wireless link stay solid when paired with phones, or are there dropouts or lag?
👉 Plug-and-Play Convenience: Can you connect it directly to your Android or iPhone via USB-C without extra adapters or apps?
👉 Battery Life: Does it last through long vlogs or interviews without needing a recharge?
👉 Smart Features: Dual channels, safety channels, real-time level monitoring, and other features that make mobile recording easier and safer.
Note: For testing, we used a variety of popular smartphones to see how these mics perform in real-world mobile recording, from vlogs and interviews to outdoor content creation.

SYNCO Smic looks like a pair of everyday wireless earbuds, but it’s designed for high-quality recording. The charging case includes a USB-C receiver and two ultra-compact transmitters with foam windscreens. You can use this USB C wireless microphone for Android and newer iPhones.
We tested the Smic with the iPhone 16, and the setup was instant. Simply plug the receiver into the phone, clip the mic onto your clothing, and start recording—no buttons, no pairing, no apps.
Compared with the iPhone’s built-in microphone, Smic delivers cleaner, richer sound both indoors and outdoors, with stable audio even when you move farther away. The AI noise reduction is more than enough for daily outdoor recording.
Each charge provides up to 6 hours of use. By rotating the two transmitters and charging them in the case, you can record continuously for up to 24 hours.

SYNCO G2(A2) dual-channel USB-C wireless microphone with display, for newer iPhones, Androids, and cameras, at $79
Unlike the Smic, the G2(A2) receiver doesn’t have a built-in USB-C plug. Instead, it features a USB-C port and comes with a USB-C cable.
If you regularly record with multiple devices—such as cameras, smartphones, and computers—the SYNCO G2(A2) is an ideal choice. With both 3.5mm and USB-C outputs, it connects easily to a wide range of devices.
Audio quality is clear both indoors and outdoors. In indoor tests with the lav mic on the subject, setting the lav gain to 0 worked perfectly. Even in a large room with noticeable echo, no echo was heard during sound checks or in post-production.
With adjustable gain control, noise reduction, and three recording modes, the G2(A2) offers greater recording flexibility. The built-in TFT display also lets you monitor settings and battery status in real time.
The G2(A2) is also available in upgraded versions to suit different recording needs:
- G2 Pro: Comes with a charging case for extended, worry-free use
- G2 Max: Features onboard recording for backup and added security
- G2 Mega: Combines both a charging case and onboard recording for maximum reliability

🗨️ “The mics auto synchronize when you turn them on, you can plug them into your phone via USB C, there is little to no noticeable latency. The sound quality is good even at this price point! The clips on the back of the devices are also magnetic, which gives you more options for mounting. ” -- Ken, content creator, US
SYNCO G3 Pro USB-C wireless lavalier microphone with 2-inch touchscreen, for newer iPhones, Androids, cameras, and PCs, at $129
Like the G2(A2), the G3 Pro features a USB-C port for both device connection and charging.
What really stands out is the included accessory kit: USB-C, TRS, and TRRS cables, plus a USB-C to USB-A adapter. This thoughtful bundle means you can connect the G3 Pro directly to smartphones, cameras, and computers right out of the box—no extra purchases needed.
In use, the sound was clear and professional, and the 2.4GHz wireless connection stayed stable even when we moved around. The dual-channel setup makes it easy to record two people at once, which is great for interviews or any collab shoots.
We tried it in different settings, such as interviews, outdoor shoots, and even windy environments, and it handled everything well, keeping voices clear while still capturing natural background sounds.
The 2-inch touchscreen is super handy too. It’s bright, easy to read, and lets us quickly check audio levels, battery life, and tweak settings on the fly.
It also comes with three recording modes, and the safety channel is a real lifesaver. No more worrying about sudden loud noises ruining a take. It just works, giving us extra peace of mind while filming.
Key features
🌟250m LOS transmission range
🌟 2-inch touchscreen for adjusting and monitoring settings
🌟 3 levels of noise reduction
🌟 15 levels of gain control

🗨️ “The mics function flawlessly. I love recorded at a max of 100 feet or so and have had no drops or latency. Sound quality is clear and it’s easy to adjust the gain using the touchscreen. The mics connect without effort. On top of all that, they look great and have a solid build quality. The red accents are nice and the LCD touch screen is gorgeous!” -- Simon M, amateur videographer, US
