Mobile phone/smartphone wired microphone JJC SGM-28 — 3.5 mm, 4 m cable, black

JJC SGM-28 is a wired lavalier microphone for mobile phones and tablets with a 3.5 mm (1/8") TRRS connector and a 4 m cable. The compact black microphone is designed to connect directly to compatible smartphones and tablets for clear voice capture during recordings, interviews, vlogs and calls. It is plug-and-play, requires no batteries, and is compatible with most recording apps that read audio from a headset input.

Advantages

The omnidirectional capsule provides 360° sound pickup for consistent voice capture regardless of microphone orientation, while the flat and smooth frequency response preserves natural vocal timbre. The long 4 m cable offers flexible placement and distance from the device, and the included clip, foam windscreen and small pouch add convenience for on-the-go use. As a wired solution with a standard 3.5 mm TRRS plug, the microphone is simple to set up and reliable for uninterrupted audio transmission.

How to use

Secure the microphone to clothing using the detachable tie-clip, position it about 15–30 cm from the mouth for clear voice capture, and attach the foam windscreen if needed to reduce plosives and wind noise. Open any recording or calling app that accepts external microphone input and start recording or speaking. When finished, detach the clip and store the microphone and accessories in the supplied pouch.

Usage recommendations

For optimal results, check device compatibility with TRRS headset inputs and test audio levels before important recordings. Use the foam windscreen outdoors or in windy conditions, and route the cable to avoid rubbing against clothing. If your device lacks a 3.5 mm input, use a compatible adapter specified by your device manufacturer.
