Sennheiser HT 747 Black Description

The Sennheiser HT 747 Black headset microphone is engineered for active professionals who demand reliability and vocal clarity. Its sleek, low-profile design includes a flexible boom arm for precise microphone positioning and a stable dual-ear mount with neckband for maximum security during movement. Its supercardioid pickup pattern sharply narrows the capture area to isolate the speaker’s voice and reduce ambient sound, making it highly effective in loud or echo-prone environments. With a 100 Hz to 15 kHz frequency response, it captures speech clearly while filtering out extreme highs and lows. Compatible with a wide range of Sennheiser bodypack transmitters and other devices using a locking 3.5mm input, this headset is a go-to choice for fitness instructors, performers, and presenters. The included windscreen reduces plosives and wind noise for smoother, more intelligible communication in any venue.
