How’s the sound quality? 

The Beyerdynamic DT 990 PRO headphones are known for their exceptional sound quality, making them a popular choice among audiophiles and music professionals. Here is a more detailed look at the sound quality of these headphones:

  1. Frequency response: The DT 990 PRO headphones have a frequency response range of 5 Hz to 35,000 Hz, which is wider than most headphones in their price range. This allows for a more detailed and accurate representation of the audio signal, with clear highs and deep lows.
  2. Impedance: The headphones have an impedance of 250 ohms, which means they require more power to drive than most consumer headphones. This high impedance is intended for use with professional audio equipment and can help to reduce distortion and improve sound quality.
  3. Soundstage: The DT 990 PRO headphones are known for their spacious and immersive soundstage, which allows for a more natural and realistic listening experience. This is especially beneficial for music production and critical listening, as it allows for a more accurate assessment of the sound.
  4. Clarity: The headphones have excellent clarity, with a detailed and transparent sound that allows for a clear representation of each individual instrument and voice. This is achieved in part by the headphones’ open-back design, which allows for more natural sound dispersion and minimizes resonance.
  5. Bass response: The headphones have a deep and accurate bass response, with tight and controlled bass that does not overpower the rest of the frequency spectrum. This is achieved through the use of high-quality drivers and careful tuning.

Overall, the Beyerdynamic DT 990 PRO headphones offer exceptional sound quality that is well-suited for music production, critical listening, and general music enjoyment. They provide a wide frequency response, excellent clarity, and a spacious soundstage that can help to reveal details in the music that may not be audible with other headphones.

What about the energy efficiency and battery life?

The Beyerdynamic DT 990 PRO headphones are a wired-only model and do not require any batteries or charging. As a result, they do not have a battery life or energy efficiency rating to speak of.

Since the headphones are designed to be used with professional audio equipment, they have a high impedance of 250 ohms. This means they require more power to drive than most consumer headphones, but they do not consume any additional power beyond what is supplied by the audio source device.

Overall, while the Beyerdynamic DT 990 PRO headphones do not have any battery life or energy efficiency considerations, they are an efficient and straightforward option for those who prefer a wired connection.

Our Review

Beyerdynamic DT 990 PRO. Basic questions, basic answers

  • Does Beyerdynamic DT 990 PRO need an amp?

    While the Beyerdynamic DT 990 PRO can be driven by a mobile device or laptop, it’s recommended to use an amplifier to fully unlock their potential. The headphones have a relatively high impedance of 250 ohms, which means they require more power to drive compared to lower impedance headphones. Using an amplifier can improve the sound quality and dynamics of the headphones, making them sound more detailed and engaging. However, it’s not a requirement and the headphones can still sound great without an amplifier, especially when connected to a high-quality audio source.

  • Is 80 ohm or 250 Ohm better?

    The choice between 80 ohm and 250 ohm Beyerdynamic DT 990 PRO headphones comes down to personal preference and intended use.

    The 80 ohm version is generally easier to drive and can be used with smartphones, laptops, and other mobile devices without the need for an external amplifier. They also tend to have slightly more bass compared to the 250 ohm version.

    On the other hand, the 250 ohm version requires more power to drive and may benefit from an external amplifier to achieve the best sound quality. They tend to have a more neutral and detailed sound compared to the 80 ohm version.

    If you’re planning to use the headphones with a mobile device or don’t want to invest in an external amplifier, the 80 ohm version may be a better choice. If you have a dedicated headphone amplifier or plan to use the headphones in a studio setting where sound accuracy is crucial, the 250 ohm version may be the better option.

  • Are the DT 990 pros good for listening to music?

    Yes, the Beyerdynamic DT 990 PRO headphones are great for listening to music, especially if you’re looking for headphones with a balanced and detailed sound signature. They have a wide frequency response range of 5 Hz to 35,000 Hz, which allows them to reproduce a wide range of frequencies accurately. The open-back design of the headphones also provides a spacious and natural soundstage, making them ideal for genres such as classical, jazz, and acoustic music.

    However, it’s worth noting that the DT 990 PRO headphones have a relatively bright sound signature, which may not be suitable for listeners who prefer a warmer or bass-heavy sound. It’s always a good idea to audition headphones before making a purchase to ensure they meet your personal preferences and listening habits.

These headphones are definitely on my wish list now! I love the fact that they’re open-back and offer such a wide soundstage. The only downside is the lack of noise cancellation, but that’s not a deal-breaker for me.
