Poly CCX 600 Business Media Desk Phone (Open SIP)

The Shure TH53B/O-MTQG is an omnidirectional headset microphone that delivers clear, natural sound while staying nearly invisible to the audience. Part of the TwinPlex series, it uses a miniature dual-diaphragm condenser capsule to capture speech and vocals with full-bodied detail, and it maintains that quality even when the source moves off axis. A wide 20 Hz to 20 kHz frequency response, low 24.5 dBA self-noise, and 117.5 dB of dynamic range ensure every subtle inflection is preserved.

Engineers and performers will appreciate the headset frame, which is both lightweight and fully adjustable. A clutch mechanism on the boom lets you change length and pitch in seconds, so the capsule sits exactly where it needs to be, then stays there throughout a show or broadcast. Because long sessions can get hot under the lights, Shure adds sweat- and moisture-resistant caps that protect the capsule and keep audio consistent.

The 1.6 mm cable resists kinks and includes a redundant ground that guards against unexpected noise if the cable is pulled or twisted. A TA4F connector makes the microphone ready for Shure wireless bodypacks, giving actors, presenters, and instructors the freedom to move without being tethered to a mixer.

From theater stages and television studios to conference halls and houses of worship, the TH53B/O-MTQG offers a blend of sound quality, comfort, and reliability that professionals can trust. Shure supplies a storage case and a full set of mounting accessories, so you can head straight to the next production or event with everything you need.
