making solder joints to connectors. Where possible it is recommended to fit crimped brass sleeves to the conductors and then solder the sleeve to the connector. If direct solder connections have to be made, use a high-temperature solder- pot to tin the tinsel conductors before making the solder joint to the connector, but be careful that the nylon thread does not melt. Direct solder connections can be made to all other cables with free ends (for cable connection refer to “Wiring Diagram” pages 14-15). On request, the necessary plugs can be mounted at the factory.

Operation

The DT 150 and DT 190 are of a professional standard. It is important that the external equipment they will be connected to are of good quality and of the correct impedance and power ratings to get the best performance from them. Please refer to the „Technical Specifications“ for detailed information.

The headphone is fully adjustable and should be positioned for the best fit over the ears. This will give maximum long-term comfort and will minimise sound leakage or spill.

Convention states that with the DT 190 the boom is placed over the left ear and the earphones of the DT 190 are identified: L and R (left and right). The microphone can be used from the right ear, but if true L and R status should be maintained, or split feeds are in operation, it may be necessary to make a custom lead with the headphone connections reversed. The L&R nomenclature plates of the DT 190 can also be swapped to reflect these changes.

DT 150 specifications

The Beyerdynamic DT 150 headphones are a well-regarded choice for audio professionals and enthusiasts alike. Established as a staple in studios and broadcast environments, they combine exceptional sound quality with robust build and comfort.

One of the primary features of the DT 150 is its closed-back design, which effectively isolates ambient noise. This feature allows users to focus on their audio without distractions, making them ideal for critical listening, mixing, and mastering tasks. The oversized ear pads offer a plush, comfortable fit, ensuring long listening sessions remain fatigue-free.

The DT 150 is equipped with high-performance dynamic drivers that deliver a wide frequency range. With a frequency response of 5 Hz to 30 kHz, these headphones present deep bass, well-defined mids, and clear highs. This broad frequency response allows sound engineers to accurately hear the nuances of the music, leading to better production decisions.

Another notable technology in the DT 150 is its low impedance of 250 ohms, making it compatible with a variety of audio sources, including professional studio equipment and consumer devices. The headphones feature a detachable cable, which is an excellent advantage for those who prefer to replace cables instead of purchasing new headphones. This feature significantly enhances the lifespan of the product.

The DT 150’s rugged construction is another highlight, as they are designed to withstand the rigors of daily use in professional environments. The adjustable headband and flexible hinges contribute to their durability, while the reinforced cable connection minimizes wear and tear.

Comfort is further enhanced by the headphone's rotatable ear cups, which allow for single-ear monitoring—a crucial feature for DJs and audio engineers who need to stay aware of their surroundings while mixing.

In conclusion, the Beyerdynamic DT 150 headphones deliver a blend of comfort, durability, and superior sound quality. With features like closed-back isolation, a wide frequency response, low impedance, and a robust build, they cater to the needs of professionals and music lovers alike. Whether for studio use or casual listening, the DT 150 stands out as a reliable choice in the headphone market. The thoughtful engineering and quality materials ensure that these headphones not only perform exceptionally well but also provide longevity and comfort in various listening scenarios.
