Tiny black adhesive microphone head on 3.5mm plug cable

Ruth's sister

Ruth's sister 3.5mm adhesive microphone 9.7x6.7mm -32dB omnidirectional

SKU CH-4Q94-FGZKW

A 3.5 mm adhesive microphone measuring 9.7×6.7 mm with omnidirectional pickup and –32 dB sensitivity for hands-free vehicle use

  • Clear calls with -32dB sensitivity omnidirectional pickup
  • Discreet 9.7x6.7mm adhesive design mounts anywhere
  • Plug-and-play 3.5mm wired connection for instant use
  • Shielded 2.5mm cable reduces interference on long runs
  • Wide 50Hz-20KHz response captures full voice range

Compact adhesive microphone

The Ruth's sister adhesive microphone measures 9.7 by 6.7 millimetres and connects through a 3.5 millimetre wired plug. It uses a dynamic transducer with omnidirectional pickup and a sensitivity of approximately minus 32 decibels. The capsule is mounted on a 2.5 millimetre shielded cable and can be fixed to glass, plastic or metal surfaces with the supplied adhesive pad.

Suited to hands-free car kits

This microphone works for drivers who need an external mic for a Bluetooth-compatible vehicle unit or stereo, and for hobbyists adding a small mic to a home studio setup. It is not intended for buyers who require a directional pickup pattern, a USB digital interface, or a professional condenser capsule with phantom power.

Omnidirectional pickup at minus 32 dB sensitivity

The single figure that decides fit is the omnidirectional sensitivity of approximately minus 32 decibels across a 50 hertz to 20 kilohertz response. If your recorder or head unit expects a higher output level or a cardioid pattern, this capsule will not match the application.

Questions about this item

Will the 3.5 mm plug work with my existing car stereo that has a 3.5 mm microphone input?

Yes, the microphone uses a standard 3.5 mm wired connection that plugs directly into any compatible 3.5 mm microphone jack on your car stereo, Bluetooth kit or GPS unit.

How can I confirm the omnidirectional capsule is picking up sound correctly after I stick it in place?

Make a test call or voice recording; the -32 dB sensitivity and 50 Hz to 20 kHz response should give clear, balanced audio from all directions without needing to aim the 9.7 x 6.7 mm capsule.

Does the package include the adhesive pad and the 2.5 mm shielded cable, or must I buy them separately?

The single microphone arrives with the adhesive backing already attached and the 2.5 mm diameter shielded wire permanently connected; no extra parts are required for installation.
