Shure TwinPlex omnidirectional headworn microphones have been designed for use in the theatre, broadcast TV, Film and AV sectors. These condenser microphones use the same element as TwinPlex miniature microphones, see SHURE MICROPHONES - Miniature however they are combined with an ‘ultra-light’ adjustable headset frame.
TwinPlex TH53 headset microphones are available in a variety of colours and with various terminations including LEMO, TA4F, MicroDot, or bare wire (unterminated). Users can replace most parts of the headset individually, including replacement boom, headset frame, earhook sleeves, cable flex etc. Please contact our Sales team for more information.

Requiring 5VDC phantom power, this dual-diaphragm condenser microphone has a low sensitivity of -45dBv (5.62mV), along with a high maximum SPL of 142dB and a dynamic range of 117.5dB. The dual-diaphragm design increases the surface area, which in turn gives ‘robust low frequency response’, gives a natural response for voice pickup, and offers low self-noise of 24.5dB equivalent.
The pre-polarised condenser capsule is housed in a moulded ABS housing giving a diameter of 5.6mm and length of 13.5mm. The 1.6m (length), 1.1mm (diameter) cable has a single, medical-grade, spiralling conductor which aids flexibility and durability. The cable is paintable and is also ‘immune to memory effects and kinks’. The included and interchangeable frequency caps are moisture and sweat-resistant thanks to their ‘superhydrophobic nanoscopic’ coating.
