Beyerdynamic DT 109 200/ 50 Black — The Broadcast Headset Standard

Beyerdynamic DT 109 200/ 50 Black is the worldwide headset standard for live, remote broadcasting, studio, film, TV and language lab applications. This dual-ear unit combines closed-back circumaural headphones with a built-in dynamic hypercardioid microphone in a single rugged chassis. Soft headband and ear pads make this model exceptionally comfortable for long on-air sessions, while the closed ear cup design blocks out ambient studio noise. What performers and broadcasters value is a reliable headset that performs shift after shift.

Built for Decades of Daily Broadcast Use

What separates it from typical studio headphones is its integrated broadcast-grade microphone and field-serviceable construction. The dynamic hypercardioid transducer rejects off-axis noise so the on-air voice stays clean in busy control rooms. Every part is replaceable, and the single-sided detachable cable lets a technician swap a damaged lead in seconds rather than retire the whole headset.

Headphone and Microphone Specifications

The DT 109 is engineered around a 50 ohm dynamic headphone driver and a hypercardioid microphone capsule, both tuned for broadcast monitoring and on-air speech. Closed-back operation and circumaural ear pads combine to give a high level of ambient noise attenuation, while the 94 dB nominal SPL means the headset can handle very loud program material without distortion.

• Wearing Style: Over-ear, dual-ear (circumaural) — full coverage of both ears for binaural program monitoring.
• Operating Principle: Closed-back — passive isolation from control-room noise.
• Nominal Impedance: 50 ohms — pairs with most broadcast consoles and camera returns without an extra amplifier.
• Frequency response covers 30 - 20,000 Hz, ensuring full-range monitoring of speech and music program material.
• Nominal SPL: 94 dB — capable of handling very high sound pressure levels.
• Microphone Polar Pattern: Dynamic hypercardioid — focused voice pickup with strong rejection of ambient noise.
• Cable: Single-sided, detachable (sold separately) — quick field replacement; choose XLR or other connector variants.

Who Should Choose the DT 109

Built for broadcast professionals, TV and film production crews, and language lab instructors, it delivers a closed-back headset with an integrated broadcast-grade microphone. Radio reporters in remote field setups will appreciate the low 50 ohm headphone impedance, which drives cleanly from camera returns and portable mixers. Replaceable parts and a detachable cable make it a long-term investment for station engineers who service their own gear. For pure music playback without a microphone, the DT 770 PRO is a better match.

Beyerdynamic: Made in Heilbronn, Germany

Hand-built at the headquarters in Heilbronn, Germany, this instrument belongs to the company's broadcast headset family. A fixture in radio and television control rooms for decades, the DT 100 series is prized for rugged construction and serviceability. The current model continues that lineage with the same closed-back circumaural design and dynamic hypercardioid microphone.
