An omnidirectional condenser lapel microphone with a 3.5 mm plug, 1.5 m cable and clip-on design for hands-free recording on smartphones, computers and loudspeakers
This wired lapel clip microphone uses a condenser transducer with an omnidirectional polar pattern to capture sound from all directions. The 3.5 mm plug provides a direct analogue connection to smartphones, computers and other devices with a compatible jack. It is intended for users who need a lightweight, clip-on solution for interviews, conferences, karaoke or general voice recording without wireless pairing.
The condenser element operates on a 3 V to 5 V supply delivered through the 3.5 mm connection, maintaining a sensitivity of -34 dB ± 1 across the 20 Hz to 16 kHz frequency range. Because the design is passive and draws minimal power from the host device, output level remains stable during long recordings without the voltage sag that can affect battery-powered wireless units. The 1.5 m cable allows comfortable movement while keeping the signal path short and free from digital compression artefacts.
The three-pole 3.5 mm connector carries a mono microphone signal plus a ground reference, so it cannot transport stereo audio or digital control data. Compatibility depends entirely on the host device wiring its jack to the CTIA or OMTP standard expected by the microphone; devices that use a different pinout or lack plug-in power will produce no signal or excessive noise. The 2.2 mm cable diameter and fixed 1.5 m length set a practical distance limit, and the analogue link offers no error correction or latency compensation.
No published specifications for this item yet.
The condenser element runs on 3 V to 5 V plug-in power from the 3.5 mm jack, so it produces no audible self-noise and no perceptible heat even after hours of continuous use.
You need a smartphone, laptop, camera or audio recorder that supplies 3 V to 5 V bias voltage on its 3.5 mm mic socket; a plain line-in or headphone-only jack will not power the capsule.
The 3.5 mm plug is a standard straight connector and the cable is 1.5 m long, so it reaches most recessed sockets on legacy cameras without an extension, though very deep recesses may still need a short adapter.
