Full details

The Sennheiser HMDC 27 Professional Broadcast Headset is designed for broadcast professionals working in extremely noisy environments. Its key benefit is active noise reduction (NoiseGuard) that preserves intelligibility, powered directly from your broadcast desk's microphone supply. A potential consideration is that this model is sold without a cable, requiring a separate purchase.

FAQs

Does this headset come with a cable?

No, the Sennheiser HMDC 27 Professional Broadcast Headset is sold without a cable. You will need to purchase a compatible cable separately.

How is the NoiseGuard feature powered?

NoiseGuard is powered via the microphone phantom power supply (typically 48V) from your broadcast desk's microphone input. No external power adapter is needed.

Can I use this headset in a quiet environment?

Yes, you can use it in a quiet environment, but the active noise cancellation (NoiseGuard) is most beneficial and designed for loud surroundings. You can choose to disable it if preferred, depending on your setup.

What is the primary advantage of the HMDC 27 over other models?

The primary advantage is its advanced Active Noise Reduction (NoiseGuard) technology, specifically engineered for extremely loud broadcast environments while maintaining exceptional audio intelligibility.

What type of audio applications is this headset best suited for?

It is best suited for professional broadcast applications in loud environments, such as live sports commentary, radio broadcasting, studio monitoring, and any situation requiring clear communication amidst high ambient noise.

Is it possible to replace the ear pads?

Yes, ear pads are typically replaceable on professional headsets to ensure hygiene and comfort over time. Please refer to Sennheiser's support documentation or contact customer service for specific replacement part information.

Troubleshooting

No sound from the headset

Verify the connecting cable is securely attached to both the headset and the audio source. Ensure the audio source (broadcast desk) is powered on and the microphone input is active. Check volume levels on the audio source.

NoiseGuard (ANC) not activating or weak

Confirm that phantom power is enabled on the microphone input of your broadcast desk. Ensure the correct cable is used, as some cables may not pass phantom power. Check if the headset is properly seated on the input.

Microphone not working

Check the microphone connection on the headset and the audio source. Ensure the correct microphone input is selected and active on your broadcast desk. Verify phantom power is enabled, as the microphone requires it.

Distorted audio

Reduce the input gain on your broadcast desk. Check for any signal clipping. Ensure the headset cable is not damaged.

Setup, Compatibility & Care

Setup:

This headset is designed to connect to standard broadcast audio equipment. Ensure you have the appropriate Sennheiser cable (sold separately) that matches your console's input. Connect the cable to the headset's designated port and then to your broadcast desk's microphone input. The NoiseGuard system will automatically draw power from the microphone's phantom power supply.

Compatibility:

Compatible with any broadcast console or audio interface that provides standard 48V phantom power for microphone inputs. The specific cable required will depend on your equipment's connectors (e.g., XLR, 4-pin XLR for headsets).

Care:

To maintain optimal performance and longevity:

  1. Cleaning: Gently wipe the earcups and headband with a soft, dry cloth. For tougher grime, use a slightly damp cloth, ensuring no moisture enters the headphone drivers or microphone capsule. Avoid harsh chemicals or solvents.
  2. Storage: Store the headset in a protective case or a safe place away from extreme temperatures, dust, and direct sunlight when not in use.
  3. Cable Management: Handle the connecting cable with care to prevent damage to the connectors or internal wiring.
