First impressions: design and portability

Right away, the SYNCO G4 stands out as a magnetic wireless mic for mobile creators or professionals who shoot on the go. The entire set fits into a sleek charging case, with space for two transmitters and three receivers — all neatly organized. This HexaCore design feels thoughtful and efficient, making it ideal for creators who are always packing or unpacking gear.

Each transmitter is small and lightweight, and the magnetic clips让 attaching them to clothing or straps quick and secure. Whether you’re wearing a jacket, backpack, or shirt, the magnets hold firm without any bulky clips sticking out. This level of convenience makes the G4 ideal for on‑the‑move creation.

How well does the magnetic wireless microphone perform?

Audio quality is where the SYNCO wireless lavalier microphones truly shines. With 48kHz/24bit sampling and an impressive SNR of 76dB, recordings sound remarkably clear and natural. I tested the system in multiple environments — quiet indoor spaces, outdoor parks, and even on busy streets — and the capture quality remained consistently strong.

The G4’s Intelligent Noise Cancellation 2.0 does exactly what it claims: it reduces ambient noise significantly (from around 90dB to 60dB in tests) without making the audio feel hollow or over-processed. Dialog recorded through this magnetic wireless microphone kept its warmth and clarity even when wind and street noise threatened to interfere.

A built-in safety channel at ‑6dB also ensures that louder speech or sudden volume spikes don’t clip or distort. For creators who want sound they can trust without chasing levels in post, this is an excellent feature.

Connectivity and range

The SYNCO G4 uses SYNCO’s Syncoder 5.0 technology, which provides a stable wireless link up to 300 meters in open environments. In practical terms, that means you can walk a considerable distance away from your camera or phone without dropouts — perfect for event coverage, outdoor interviews, or street‑style vlogging.

Pairing the units is straightforward: once powered on, the system recognizes the connected receivers and locks onto them automatically. Whether you attach a magnetic wireless mic for the iPhone via the Lightning receiver or use USB‑C on an Android device, setup is quick and hassle‑free.

Battery life and usability

Battery life is a key factor for any wireless system, and the G4 delivers respectable performance. Each transmitter lasts up to 8 hours on a single charge. When placed back into the charging case, you can get an additional 1.5 full charges — ideal for long shoots or multiple sessions in a day.

The charging case itself is compact and durable, making power management easier on the go. Also, the magnetic tuning clips and necklaces give flexibility in how you wear the transmitters — whether clipped to clothing or resting discreetly under a shirt.

This makes the SYNCO G4 a compelling wireless magnetic mic for vlogging or lightweight production setups where you don’t want bulky gear weighing you down.

Real‑world use cases

Vlogging and social content

For vloggers and mobile creators, the G4 is both easy to deploy and produces audio quality that surpasses built‑in phone mics by a huge margin. The magnetic mounts allow for quick transitions between handheld and on‑body setups, which is invaluable when switching scenes.

Interviews and professional shoots

In interview settings, the dual transmitter configuration lets you record two people simultaneously. Once synced, the audio remains clean and balanced, reducing time needed for later edits. This is especially useful when shooting with a lightweight rig or engaging directly with interviewees.

YouTube and longer form content

The G4’s reliability and long battery life also make it suitable for content creators on platforms like YouTube. Whether you are teaching, reviewing products, or recording storytelling segments, the consistent audio keeps the viewer experience professional — exactly what you’d expect from a wireless magnetic mic for YouTube.
