Beyerdynamic DT900 PRO X Headphones - Over/On Ear Selling a pair of Beyerdynamic DT900 Pro X open back headphones that are two months old and in mint condition. I have upgraded to a set of Sennheiser headphones that I bought at the recent Sydney Audio Show at a discounted 'show' price. The set includes the headphones, two cables at 1.8 and 3 meters in length, a carry pouch along with the instructions and original box. I had thought of keeping these but have decided to sell and put the funds towards some new interconnects instead. Happy to send interstate but postal charges are additional to th

The Beyerdynamic DT900 PRO X is a highly regarded open-back studio headphone featuring the Stellar.45 driver developed in Germany, offering exceptional detail and long-wearing comfort for producers and engineers. Its 48-ohm impedance and wide 5Hz–40kHz frequency response make it versatile for both studio mixing and critical listening. Since the item is listed as like_new with original packaging implied by typical dealer listings at this price point, you’re getting near-new performance without the new retail cost of roughly A$369–A$399. At A$225, this is a clear buying opportunity for anyone seeking premium open-backs without overspending.

Beyerdynamic traces its roots to 1924 Berlin, where engineer Eugen Beyer founded Elektrotechnische Fabrik Eugen Beyer to produce cinema loudspeakers for the dawn of sound films. Born in St. Petersburg in 1903, Beyer relocated amid the Russian Revolution, pioneering dynamic drivers that defined early audio reproduction. Post-World War II destruction forced a rebuild in Heilbronn in 1948, with his son Fred R. Beyer steering the family-owned firm through decades of innovation until its 2025 acquisition by China's Cosonic Intelligent, marking the end of a century-long German heritage.
The brand excels in headphones and microphones, launching the DT 48 in 1937 as the world's first dynamic headphones—a staple for sound engineers until 2012. It expanded into wireless systems, conference tech, and professional monitoring gear, serving studios, broadcast, film, and now gaming. While early efforts included amplifiers and loudspeakers, Beyerdynamic prioritizes transducers over consumer amps, DACs, turntables, speakers, or cables.
Renowned for durable, reference-grade professional audio, Beyerdynamic occupies a solid mid-to-high-end niche, blending accessible pricing with studio precision that appeals to creators and audiophiles. Its century of milestones—from micing royalty to touring icons—cements a reputation for reliability and sonic purity among discerning hi-fi buyers seeking tools that endure.
