So, we’re putting it to the test in this Beyerdynamic DT 900 Pro X review.

But first, let’s check out the packaging and what items are included.

Of course, there’s the eye-catching orange lengthwise strip on the right side of the box’s front. This strip features an image of the headphones itself, while Beyerdynamic and its logo are just above it. Below the image, you’ll see the name of the product written.

Aside from the headphones, Beyerdynamic included a couple of other items in the package. There’s a drawstring carrying pouch, two straight jack cables with gold-plated plugs, plus gold-plated screw-on adapters. Other than these, you’ll also find a leaflet with an instructional manual and promotional brochures included.

It’s sturdy and durable like other models from the company. And, these should be able to readily withstand the perils of transportation, travel, and more. 

As we continue our Beyerdynamic DT 900 Pro X review, we’re also going to discuss its components. We found out that the headphones feature the Stellar.45 sound transducer. 

This Germany-made sound transducer comes with a three-layer speaker diaphragm that utilises a built-in damping layer. This helps the DT 900 Pro X perform consistently and efficiently across devices. 

Furthermore, the driver allows the headphones to not be as dependent on an amplifier for ideal volume. And this is just like with the Pro Series.

Now, our Beyerdynamic DT 900 Pro X review will focus on the specifications of these headphones. Let’s see what makes it different and better from other similar products on the market. 

The DT 900 Pro X is a dynamic transducer type of headphones with an opened operating principle. It has a circumaural sound coupling as well. Additionally, it comes with a frequency response ranging from 5 to 40,000Hz and a nominal impedance of 48 Ω.

For its nominal sound pressure level @1 mW / 500Hz, it’s at 100dB SPL. But when it’s @1 V / 500Hz, it’s 114dB SPL.

Its short-term maximum input power is 100 mW, and its rated maximum input power under continuous operation is 30 mW.

For its THD @1 mW, the headphones is 0.80% @ 100Hz, 0.05% @ 500Hz, and 0.04% @ 1kHz.

When it comes to its headband pressure, the DT 900 Pro X is 5.3N. Plus, it weighs 345g without the cable.

Hands-on with the Beyerdynamic DT 900 Pro X

As we covered in our how to Choose the Right Open-back Headphones for Gaming guide, the DT900 Pro X offers amazing sound. For its soundstage, it was a bit wider compared to past models and Beyerdynamic does an excellent job at creating a huge sense of separation and space. 

The lows of the DT 900 Pro X are tight and full of impact. Thus, it gives lots of balance and accuracy to its tuning. We greatly enjoyed its ability to capture the nuances of different bass and percussion timbres. 

If you’re planning to utilise these for casual listening, that’s fine. You’ll find that its more controlled lows make the headphones versatile across styles and genres. 

On the other hand, if you’ll use them for mixing and music creation, that’s fine too. That’s because you’ll find the low-end unbiased and easy to work with. 

The DT 900 Pro X offers a clean and fairly-coloured mid-range. At times, its high-mids take precedence over the low-mids. However, the low-mids are still maintained to keep the headphones’ warmth fully intact.  

The high-mids have a nice snap. However, the saturation rounds off edges that may be slightly overly-crisped up. 

For its mid-range, these feel like the most distinguished quality of the DT 900 Pro X. That’s because It has a specific timbre that brings a lot of excitement and flair to the music. Plus, it brings out distinct aspects of the vocal presence and instruments. 

These DT 900 Pro X headphones are clearly bright. However, these stay below the threshold of intense treble meaning they are always a comfortable listen.

Paired with the cleaned mids and neutral lows, these headphones’ additional crisp highs bring a light and airy sound. So if you’re looking for a more heavy and gritty feel, the DT 900 Pro X isn’t aiming for that.

Overall, the Beyerdynamic DT 900 Pro X sonically bears a lot of similarities to the DT 990 Pro. This is most evident in its highs and lows. 

However, these headphones have a better soundstage compared to the earlier models. Plus, it has tighter handling and more cleanliness. 

We also loved the solid stereo impression that these headphones produced. And lastly, the detail of its treble had a positive influence over its entire signal resolution. We especially noticed this when listening to acoustic tunes that sounded lively and wonderfully uncompressed with these headphones. 

The mix of its fine reproduction, open design, and lively dynamics also had a great effect on the impression of spatial depth. The whole sound image appeared three-dimensional. And considering its price range, the Beyerdynamic DT 900 Pro X feels just like a gift. 

Beyerdynamic DT 900 Pro X Review Summary

The new Beyerdynamic DT 900 Pro X is an impressive pair of over-ear headphones. It offers great sonic transparency, treble-emphasised signal, and unobtrusive bass. These are particularly suitable for isolating subtle nuances, making it excellent for audio mixing and processing.
