Beyerdynamic DT 990 & DT 770 share many similarities, but there are also important differences, such as sound quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Beyerdynamic DT 770 rather than the Beyerdynamic DT 990. 

Why Do I Recommend The Beyerdynamic DT 770

  • The Beyerdynamic DT 770 supports high-resolution audio & features a more refined sound profile with enhanced bass response and clearer highs, while the Beyerdynamic DT 990 does not match the fidelity and depth.
  • It comes with noise isolation for environments with background noise, while the open-back DT 990  leaks sound and requires a quiet listening environment.
  • Beyerdynamic DT 770 emphasizes tight bass and controlled treble to enhance the overall experience, while the DT 990 offers elevated bass.
  • The Beyerdynamic DT 770 has a snug fit for long listening sessions, while the DT 990 offers velour pads.

Maybe the Beyerdynamic DT 990 price can make you comfortable because it’s a little bit cheaper than the Beyerdynamic DT 770. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.

FAQ

Q1: What is the main difference between the DT 770 PRO and the DT 990 Premium Edition?
The primary difference lies in their design. The DT 770 PRO is a closed-back headphone, which provides excellent noise isolation and minimal sound leakage, making it ideal for studio use. The DT 990 Premium Edition is an open-back headphone, offering a wider soundstage and natural audio, better suited for home and audiophile listening.

Q2: Can I use either headphone without an amplifier?
Both models have a 250-ohm impedance, which requires a powerful headphone amplifier or a device capable of driving high-impedance headphones. Without an amplifier, the volume and sound quality may not reach their full potential.
