The following article looks at these headphones in depth to find out why they are so highly regarded.

Beyerdynamic DT 990 Pros Review: Best Piano Headphones?

Sound Quality

The DT 990 Pros are known for their balanced and detailed sound signature, with a wide soundstage that allows for precise instrument separation. Their high-frequency range is impressive, providing crisp and clear treble without harshness.

The midrange is well-balanced, and the bass is accurate and tight without being overpowering. Their open-back design provides a natural and immersive listening experience, making the DT 990 Pro ideal for critical listening and monitoring.

The sound of these headphones is described as transparent and spacious, with detailed tonal depth.

Comfort and Design

The DT 990 Pro’s design is simple and elegant, with a matte black finish and silver accents (on the standard edition).

An open-back design helps to reduce heat buildup, and they have soft and replaceable velour ear pads that make the headphones comfortable to wear for long sessions.

These are also very lightweight headphones, and the adjustable headband ensures a comfortable fit for a wide range of head sizes. They are comfortable for the majority of users for long sessions in the studio or general use.

Durability

Made in Germany with precision and attention to detail, Beyerdynamic headphones are well-known and trusted by studios, musicians, and podcasters around the world for their reliability and longevity.

Though mostly plastic in construction, the DT 990 Pros are built to last, with a high-quality and durable build. Plastic also helps to keep weight down which is important for comfortability.

Compatibility

The DT 990 Pro comes in 80 and 250-ohm variants. The 250-ohm model is designed to be used with an amp, the 80-ohm model can be powered by your laptop or phone.

I use the 80-ohm DT 770s with a MacBook and smartphone regularly and I have never had any issues with the volume or audio quality. They have also lasted for several years and through a few house moves as well.

The only real downside with the 990s is the lack of a removable cable. It is a shame to have to spend an extra $100 for that luxury. On the plus side, the cable is very hardwearing.

The coiled cable ends in a 3.5mm jack, and you can screw on the included 1/4-inch adapter if you’re plugging it into a mixer or interface.

One thing to be aware of with these being open-back headphones is that they take in dust and dirt more easily than closed-backs. These are ideal for studio and home listening, but not a good option for commuting or generally wearing outside.

Another option is the Sony MDR-7506 headphones. These are significantly cheaper at just under $90 but do not offer quite the same level of audio quality, frequency response, or comfort, as the 990s or Audio-Technica M50X.

Still, if you are looking for some closed-back studio headphones on a budget, then the MDRs are a good choice and ideal for beginners.

FAQ

What Other Models and Special Editions Are There?

Before you decide on these headphones, you should know about the other models in the Beyerdynamic range. They have several popular models in both open and closed-back designs, with varying prices and features.

Both the DT 700 and DT 770 are extremely popular closed-back headphones, that are worth a look if you are still undecided between the closed and open designs.

The 770’s in particular, are one of the best-selling closed-back studio headphones on the market.

The DT 900 headphones have an open-back design and they share similarities with the 990 Pros. They have a detachable cable and different earcups and are also more expensive.

These are worth considering if you have the budget and appreciate the added features, and included accessories.

What Are Open-Back Headphones?

Open-back headphones are ideal for mixing and mastering music, as well as for audiophiles and general listening, for anyone who likes flat and precise audio.

Open-backs have far more ‘sound leakage’ meaning others in the room will hear what you are listening to. However, they also have the benefit of a more natural, ‘spatial’, and open sound compared to closed-back headphones.

This is one reason the DT 990 Pro X headphones have excellent audio clarity, and are ideal for home studios, recording, and mixing music.

What Is OHMS?

You should be aware of which ohms (impedance) your headphones have. Higher ohms rating will require more power to run the headphones, and you will need a headphone amplifier to run them.

OHMS is a standard unit that refers to the amount of impedance provided by a given set of headphones. Represented by the symbol Ω, Ohms measure the level of electrical resistance of a circuit to alternating current.

Whilst 250 or 600-ohm headphones provide slightly better quality audio, for most users, running the 32 or 80-ohm headphones will suffice.

They will provide enough of a quality listening experience for everyday mixing and monitoring, or general use, and will not require additional hardware to power them.
