Beyerdynamic DT 990 Pro X

Product information "Beyerdynamic DT 990 Pro X"

The DT 990 PRO X is a pair of open-back studio headphones for analytical listening and precise editing in the studio. Its treble lift and high transparency make acoustic inaccuracies clearly audible. It can be used as a complementary tool to studio monitors during the production process.

Thanks to the low-impedance STELLAR.45 driver, the headphones are compatible with a variety of playback devices.

The detachable, single-sided routed mini-XLR cable makes handling the headphones easier when they need to be put on and taken off frequently.

The robust spring-steel headband provides a secure fit and the mechanical reliability required for daily use.

Soft headband and ear pads contribute to a high level of long-term wearing comfort. The headband and ear pads can be replaced if necessary.

The connection cable is fitted with a gold-plated mini stereo jack (3.5 mm) with a 6.35 mm adapter and can be connected to all common headphone outputs.

About Beyerdynamic

Perfect sound is our yardstick

In 1924 Eugen Beyer founded his own company to build cinema loudspeakers. The "Elektrotechnische Fabrik Eugen Beyer" thus developed into a world‑leading producer of microphones, headphones, headsets and conference systems.

With the highest standards of quality, engineers in Germany have been designing, testing and producing outstanding sound for almost 100 years. The in‑house developed Tesla technology ushers in a new era of headphones and is a unique selling point for Beyerdynamic in a highly competitive market. The drivers, redesigned from the ground up, feature an extremely strong magnetic drive and low‑colouration reproduction. Named after Nikola Tesla, the pioneer of alternating current, Tesla technology enables flexible applications and opens a new dimension in headphone listening pleasure.

The right headphone for the right application

Beyerdynamic divides its headphone range into the areas: at home, on the go, high‑end, broadcast, studio, gaming and home office. Whatever application you choose, many of the products feature technology from the latest generation. Whether hi‑fi headphones or studio headphones—features such as Tesla technology, Active Noise Cancelling (ANC), limiters or Bluetooth can be found in many models. With MOSAYC sound personalisation the headphone can be tuned to the user's individual listening taste and custom settings can be created.

Sought‑after models: products from the Beyerdynamic DT series are consistently popular and in high demand. Examples include the DT 770 Pro and DT 880 Pro.

Microphones, systems and series

For a wide range of applications there are wireless or wired solutions. Whether for speech, stage, presentation, studio recording, video conferencing or broadcasting, the live and studio microphones leave little to be desired. Polar patterns range from cardioid, supercardioid and hypercardioid to omnidirectional and figure‑of‑eight.

For practically every instrument type—string instruments, wind instruments, guitar, percussion, drums and keyboards—there is the right transducer. The Beyerdynamic TG series, in particular the clip‑on microphones TG D57c and TG D58c, are very popular.

We also offer the appropriate product for measurements and calibration. For example the MM‑1, which is available here in our shop.
