Which Headphones Offer Better Noise Isolation? Hd 660S Vs Beyerdynamic Dt 1990 Pro

by

Choosing the right headphones for noise isolation is essential for audiophiles, professionals, and casual listeners alike. The HD 660S and Beyerdynamic DT 1990 Pro are two popular models renowned for their sound quality, but how do they compare in terms of noise isolation? This article explores their features to help you make an informed decision.

Overview of the HD 660S

The Sennheiser HD 660S is a semi-open-back headphone designed for audiophile listening. Its open-back construction allows for a natural and spacious sound experience, but it also means that noise isolation is limited. The headphone features a lightweight design, comfortable ear pads, and a detailed sound profile that emphasizes clarity and accuracy.

Overview of the Beyerdynamic DT 1990 Pro

The Beyerdynamic DT 1990 Pro is a premium open-back headphone favored by professionals in studios and critical listening environments. Its open-back design provides excellent soundstage and clarity but offers minimal noise isolation. The DT 1990 Pro is known for its durability, detailed sound, and comfort during long listening sessions.

Noise Isolation Comparison

Both the HD 660S and DT 1990 Pro feature open-back designs, which inherently limit noise isolation. However, there are differences in how they handle external sounds:

  • HD 660S: Offers slightly better noise isolation than the DT 1990 Pro due to its semi-open design, which partially seals the ear cups, reducing ambient noise.
  • Beyerdynamic DT 1990 Pro: Provides minimal noise isolation because of its fully open-back architecture, making it unsuitable for noisy environments.

Practical Implications

If noise isolation is a priority, neither of these headphones are ideal for noisy environments. They are best suited for quiet rooms, studios, or controlled listening settings. The HD 660S may be preferable when some external noise reduction is beneficial, but for complete isolation, closed-back headphones are recommended.

Conclusion

In terms of noise isolation, the HD 660S offers a marginal advantage over the Beyerdynamic DT 1990 Pro due to its semi-open design. However, both models are fundamentally open-back headphones and are not designed to block out ambient noise effectively. For better noise isolation, consider closed-back or noise-canceling headphones.
