Beyerdynamic DT 990 Pro X

With the PRO X line, Beyerdynamic introduces a new generation of professional studio headphones that blend proven concepts with today’s technology. The Beyerdynamic DT 990 Pro X fits seamlessly into this range with high comfort, fine detail resolution and an open, over-ear design—enabling demanding tasks such as mixing, editing and critical signal assessment both in the studio and on the go.

Scope of Delivery

The accessory pack for the Beyerdynamic DT 990 Pro X is straightforward. Alongside the headphones, you’ll find a 314 cm straight detachable cable. A gold-plated 3.5 mm plug comes pre-fitted, while a matching screw-on 6.35 mm adapter is included. There’s also an unpadded drawstring pouch—handy for keeping dust and scratches at bay during storage or transport. A printed manual explains cable connection and how to replace the head- and ear-pad cushions.

Classic Design & Premium Build

The Beyerdynamic DT 990 Pro X sports a calm, classic aesthetic that underscores its professional intent. As expected, Beyerdynamic’s high manufacturing quality leaves nothing to criticize. Robust materials and German production create an instantly durable impression: the headband uses spring steel and many plastic parts are glass-fiber reinforced.

Because ear and head pads can be removed and replaced with ease—and all critical joints are secured with screws—users invest in a long-lasting piece of gear. Nothing should stand in the way of heavy professional use. Beyerdynamic also notes that many DT 990 Pro X materials are not only premium but sustainably sourced.

Wide Audio Spectrum

Like other PRO X headphones, the Beyerdynamic DT 990 Pro X employs the newly developed STELLAR.45 drivers. A three-layer diaphragm, highly efficient coils and strong neodymium magnets let them span an ultra-wide 5 Hz to 40 kHz—exceeding the human hearing range at both ends.

The DT 990 Pro X also follows the PRO X series’ low-impedance formula at 48 ohms. That makes it suitable for studio interfaces, laptops and smartphones whose headphone outs often supply less voltage than dedicated amps. Its weight is just 289 g (sans cable), so it needs little clamp force—ideal for lengthy sessions.

Comfort Meets Operational Safety

Adjusting the headband size feels a bit stiff on the Beyerdynamic DT 990 Pro X, yet the click stops ensure your setting won’t shift accidentally. Replaceable velour pads use ultra-soft memory foam that gently conforms to your head.

The likewise replaceable headband pad uses ergonomically shaped visco foam—easing pressure at the crown. Together with the low clamping force, this keeps the DT 990 Pro X comfortable for extended wear. Breathable velour also keeps your ears cool over marathon sessions.

Once seated, headband and pads distribute pressure evenly, giving a secure fit. Quick head turns don’t dislodge the DT 990 Pro X. Its detachable cable connects via mini-XLR, locking in place to prevent accidental pull-outs. With single-sided entry on the left cup, right-handed users enjoy extra freedom of movement.

Detailed Sound with Strong Dynamics

The Beyerdynamic DT 990 Pro X serves up precise, deep-reaching bass. Unlike many open-back designs, lows aren’t shy—yet remain tightly controlled, making these cans ideal for analyzing sub-content in mixing and editing. Sub-bass never overwhelms but has ample presence.

Mids portray speech and vocals with clarity and nuance. Instruments anchored in this region—guitars, synths—gain focus without fatigue, even with heavily distorted material.

Above that, the DT 990 Pro X delivers detailed, “full-bodied” highs free of harsh sibilance. Depending on the production, cymbals and other treble elements can lean forward yet never cross into unpleasant territory. Resolution stays high all the way into the air band—open and transparent.

Its open, over-ear build further enhances spatial realism. A wide stereo field and impressive depth make it easy to pinpoint sources in the mix. Micro-detail extends into dynamic expression: sharp transients render subtle textures, while quiet passages remain nuanced and full-scale orchestral tuttis play loud and clean—no distortion even at high SPL.

Perhaps most impressively: the DT 990 Pro X delivers this performance whether driven by top-tier studio gear, budget interfaces or a laptop.

Conclusion

Our tests show the Beyerdynamic DT 990 Pro X to be a high-grade studio tool that excels on multiple fronts. From understated design and premium materials to excellent build, exceptional comfort and finely resolved, spacious sound, it ticks every box. Low impedance affords flexibility across devices, while service-friendly construction boosts reliability. Only a soft case is missing at this price point.

Bottom line: the DT 990 Pro X empowers musicians, engineers and creators to judge complex audio comfortably over long sessions. Thanks to its strong price-performance ratio and nuanced sonic profile, it belongs not only in pro studios but also in home setups and dedicated hi-fi rigs.
