beyerdynamic DT 990 PRO X | beyerdynamic Australia | RRP: $399

beyerdynamic produce headphones that are built to last. From robust build quality to replaceable headbands, ear cups and cables. There’s something about a great pair of headphones that helps us more easily understand the musical moves we’re making, especially with a low ohm rating like the beyerdynamic DT 990 PRO X. The STELLAR.45 drivers (48 ohms) allow you to easily jump between studio and home without struggling to drive them without a headphone amp, making them perfect for referencing on the go.

DT 990 PRO X

These headphones are built in Germany by people who understand what it’s like to have a trustworthy pair of headphones that you rely on session after session, no matter where you are.

The revised drivers are just the beginning of a classic headphone renewed, the DT 990 PRO X building on the classic DT 990 PRO’s design, being an open-back design as opposed to the 770s that can be used for more isolation to both listener and those around you.

The low end on the DT 990 PRO X is true, and not overtly hyped like in some headphones. There’s an air of accuracy to it all, without being clinical, and I quickly found myself identifying issues that might’ve otherwise slipped through. Roughly balancing a mix on the DT 990 PRO X’s had my work translating better than before on a few different systems, also allowing me to jump between the studio and home with the same great, precise and accurate sound. The open-back design provides a natural lift to everything, without introducing harshness, and instead feels like a spotlight on your music, problem areas (and the solutions) immediately illuminated.

Open-back headphones

The DT 990 PRO X feature beyer’s classic open-back design, being supremely comfortable for extended periods of time, the open-back allowing for airflow as well as a more balanced sound and giving the drivers space and air to breathe.

The addition of the PRO X brings the STELLAR.45 to the already classic headphone design used around the world. beyerdynamic’s closed-back design in the 770s provide superior isolation for recording, while the 990s are supremely suited to editing and critical listening, providing an airy sound and comfort for long sessions. These also respond from 5Hz up to 40kHz, meaning you’ll feel and hear every ounce of sound from your source.

Detailed sound makes the DT 990 PRO X a great companion for the producer on the go. Use them at the studio with a headphone amp, but trust them equally at home on a laptop, or even referencing mixes on your phone on the go!

The aforementioned STELLAR.45 drivers feature neodymium magnet and precision copper coil for sound that is dynamic, low-distortion and very true to source; above all else, they’re trustworthy.

The headphones include a removable mini-XLR connection, allowing you access to various cable types and lengths, i.e. for connection directly to a smartphone or other system. For coiled cable devotees like myself, the removable cable is a great addition!

The headphone band and ear cups are removable and cleanable, allowing for a lifetime of care and maintenance on the beyerdynamic DT 990 PRO X. Building on the classic DT 990 PRO design, a studio mainstay, the DT 990 PRO X features a more comfortable, redesigned headband featuring a fontanelle recess; these headphones are with you through and through and won’t be a problem working for hours and hours! When inspiration strikes, the last thing you want is a hindrance! The headphone jack and included ¼” adapter are also both gold plated, ensuring premium audio is transmitted for a lifetime!

Supremely matched for critical listening, the 990 PRO X’s design has audio anomalies, imperfections, mistakes and edits clearly audible, a match made in heaven when referencing against a set of equal trust studio monitors. A few different places to reference mixes and music is an incredibly important tool for music makers, some great studio monitors are fantastic, and are a great set of headphones can be used to reference both in the studio and on the go— and there’s nought much better than the new DT 990 PRO X, a studio classic revised for the modern day and filled with all that beyerdynamic has to offer.
