The Beyerdynamic DT 990 Pro X represents a significant evolution of the classic DT 990 Pro headphones. This review delves into the improvements and refinements offered by the new model, focusing on its key upgrades and overall listening experience. We'll examine the impact of a detachable cable, the lowered impedance, and a revised sound tuning compared to its predecessor. We'll also explore how these changes affect the headphone's suitability for various applications, including studio work and gaming.This in-depth analysis will cover not only the physical enhancements but also a detailed sonic evaluation, comparing the DT 990 Pro X to its predecessors and competitors like the Beyerdynamic 900 Pro X and the Sennheiser HD 6XX. We will assess the accuracy of Beyerdynamic's claims regarding their intentional tuning choices and determine whether the resulting sound signature lives up to its intended purpose and justifies its place in the competitive headphone market.
Pros And Cons
- Detachable cable
- Lower impedance (48 ohms), making it easier to drive
- Improved driver consistency leading to better channel matching
- More neutral sound profile compared to older models
- Good bass tactility and extension
- Surprisingly good for gaming due to energetic and wide sound
- Thinner carrying pouch offers less protection
- Some may prefer the ear cup design of the older model
- The treble emphasis might accentuate breathy vocals or sibilance for some listeners

Notable Improvements: Detachable Cable and Lower Impedance
One of the most significant upgrades in the Beyerdynamic DT 990 Pro X is the inclusion of a detachable cable. Previous versions, the 250-ohm and 80-ohm models, suffered from a fixed cable, a minor inconvenience but a significant improvement for modern standards.
Beyond the cable, the impedance has been drastically reduced to 48 ohms from the previous 250 ohms. This makes the DT 990 Pro X incredibly easy to drive, eliminating the need for a powerful amplifier for optimal sound reproduction. This increased efficiency also allows for direct connection to devices like gaming controllers.
Also included in the package is a thin carrying pouch. While providing some protection against dust and scratches, it's not ideal for heavy-duty travel or protection against significant impacts. It serves more as a dust cover than a robust case.
Intentional Tuning and Design Choices
Beyerdynamic intentionally designed the DT 990 Pro X with a specific sound signature. Their product manager stated the headphones are meant to highlight subtle mix imperfections, making them ideal for studio use. This explains the historical presence of a treble peak in previous models.
This intentional coloration isn't a flaw; it’s a design choice. The notorious 8000Hz peak in older models, now significantly reduced but still present in the DT 990 Pro X, is a result of this design philosophy. These headphones prioritize revealing details critical for sound engineering rather than solely focusing on pleasing listeners.
The review acknowledges this design approach. While the sound quality will be critically analyzed, the reviewer emphasizes that the DT 990 Pro X's unique tuning is deliberate and targeted toward a specific user base. This is not a 'get out of jail free card' for potential flaws.
Design and Build Quality Comparison
The headband and overall design remain largely unchanged from the previous DT 990 Pro. However, the new model proudly displays the Beyerdynamic branding on the top. Parts remain user-serviceable, reflecting Beyerdynamic’s commitment to long-term product ownership with replaceable components.
The earcups show subtle differences. While similarly designed, the reviewer prefers the embossed 990 branding on the older model, finding it more premium than the flat branding on the new Pro X. The new model features a textured finish for enhanced grip and robustness compared to the smoother finish of its predecessor.
Ear pads retain a 55mm diameter and 25mm depth, ensuring a similar fit and feel as the older model. While the acoustic discs have a slightly different design, the overall depth remains consistent, minimizing changes in the user experience. A pressure-relieving indent on the new headband’s top aims to improve comfort during extended use.
Objective and Subjective Sound Quality Analysis
Measurements using a Gross KB00006X pinnacle reveal a significant reduction in the 8000Hz peak on the DT 990 Pro X compared to the older model. The bass response in the new model is much more linear and extends lower, unlike the warmer, more V-shaped response of the older model.
Subjectively, the DT 990 Pro X sounds more neutral than expected, with a less sibilant and more natural mid-range. However, a subtle peak remains in the high treble. The 3-4kHz region contributes to the brighter, more revealing character, as intended by Beyerdynamic’s design philosophy.
The reviewer notes that the DT 990 Pro X’s treble emphasis adds to the perception of certain sounds. Breathy vocals, metallic instrument strikes, and snares all exhibit more presence and snappiness than on the older model. This character, while subjectively different, is again intentional design.
Comparison with other Beyerdynamic Headphones and the Sennheiser HD 6XX
The reviewer also compared the DT 990 Pro X to the Beyerdynamic 900 Pro X and the 1990 Pro Mark II. The 900 Pro X has a similar bass profile but is more relaxed overall, while the 1990 Pro Mark II, despite a similar treble emphasis, presents a more resolving and technical sound.
The Sennheiser HD 6XX is another $200 competitor with a more neutral, highly resolving sound profile. However, the HD 6XX is less impactful in the bass region compared to the DT 990 Pro X.
The reviewer notes that while the 900 Pro X and HD 6XX excel in certain areas, the DT 990 Pro X offers a more balanced profile and a surprising amount of bass impact for a headphone of its price point.
Gaming Performance and Conclusion
The DT 990 Pro X is surprisingly good for gaming due to its more energetic and open soundstage. The older DT 990 Pro, with its strong treble peak, is less suitable. The 900 Pro X, with its smoother sound and more pronounced bass, is also a good option.
Ultimately, the best choice depends on individual preferences. The DT 990 Pro X is a great upgrade from the older 250-ohm model, thanks to its detachable cable, lower impedance, and tamer treble. It provides a more balanced sound profile than the older model, making it more versatile for various use cases.
The 900 Pro X might be a preferred choice if a more neutral, relaxed sound signature is desired. The Sennheiser HD 6XX remains a top contender for its detailed, resolving sound, although it lacks bass impact.
