Sennheiser Manuals & User Guides

Sennheiser is a globally renowned German manufacturer of high-fidelity audio equipment, including headphones, microphones, and business communication solutions.

Founded in 1945 by Fritz Sennheiser, the company is headquartered in Wedemark, Germany, and has built a reputation for excellence in sound engineering. Its product lineup spans from consumer electronics—such as the acclaimed MOMENTUM wireless headphones and AMBEO soundbars—to professional audio gear used in film, music, and broadcasting, including the legendary MKH 416 shotgun microphone.

The brand's operations are divided to better serve its customers: professional audio solutions remain under Sennheiser electronic SE & Co.

• Why am I not getting any sound from my Sennheiser wireless system?

  Check all audio connections between the transmitter and your audio source. Ensure volume levels on both the transmitter and source are adjusted appropriately. If using a digital optical connection, verify that your source device's audio output is set to a compatible format like PCM, as some systems do not support Bitstream/Dolby directly.

• How do I connect my Sennheiser transmitter to a TV?

  Identify the audio output on your TV (Analog 3.5mm/RCA or Digital Optical). Connect the corresponding cable from the TV's output to the transmitter's input. For optical connections, remove the protective caps from the cable before insertion.

• How can I troubleshoot microphone issues with my Sennheiser headset?

  Ensure the 3.5mm plug is fully inserted into the jack. If using a smartphone without a headphone jack, use a compatible official dongle (USB-C or Lightning) that supports microphone input. Also, check that the in-line mute switch is not active.

• Where can I find the latest firmware or manuals for my device?

  You can download user manuals and software updates directly from the Sennheiser Hearing download center at www.sennheiser-hearing.com/download.

• What do the LED indicators on my wireless headphones mean?

  LEDs typically indicate power status, battery level, or pairing mode. For example, a flashing light often means the device is in pairing mode, while a solid light indicates a successful connection. Refer to your specific model's quick guide for exact color codes.
