Point Source Audio CR-8D-XTX-BR Cardioid Headset Microphone

The Point Source Audio CR-8D-XTX-BR is a miniature cardioid condenser headset microphone engineered for professional live performance, theatrical production, and broadcast environments where every centimeter of visibility matters. The cardioid polar pattern is the defining sonic characteristic here — it introduces rear rejection into a form factor that most headset mics traditionally omit in favor of omnidirectional simplicity. In a crowded stage mix with eight or ten open bodypack channels, that rejection isn't cosmetic; it's the difference between a clean, isolated vocal track and a wash of cross-talk that burdens the FOH engineer throughout the show. Placement at the corner of the mouth positions the capsule away from direct plosive airflow, letting the cardioid pattern work as intended rather than fighting breath noise artifacts.

Build quality centers on the Unbreakable Boom — a differentiating feature in a product category where boom wire fatigue and breakage are among the most common failure points. The 360-degree bendability gives sound team members the freedom to shape the boom precisely for each performer's anatomy and returns reliably to position, night after night. The convertible left/right ear design and adjustable boom length reduce inventory complexity for production companies outfitting large casts. The 4-pin mini Telex connector means this specific variant is ecosystem-locked, so it rewards companies already running Telex wireless infrastructure rather than mixed-platform houses — a consideration worth factoring into a rental or purchase decision before the first rehearsal.
