Third-party reviews

What customers like about Beyerdynamic DT660

  • Excellent noise isolation for a closed-back design, suitable for libraries and flights
  • Detailed audio reproduction with a neutral/flat sound signature
  • High comfort levels with well-padded headbands and soft, replaceable earpads
  • Low 32-ohm impedance makes them easy to drive with portable devices without an amp
  • Foldable design with 90-degree swiveling ear cups for easier transport and storage

What customers don't like about Beyerdynamic DT660

  • Non-detachable cable makes it difficult to replace if damaged
  • Significant use of plastic in construction, particularly in the hinges, which may feel fragile
  • Can sound overly bright or sibilant, leading to ear fatigue during long listening sessions
  • Relatively heavy compared to some portable alternatives
  • Stock cable is very long (3 meters) and not coiled, which can be cumbersome in office or portable use

Verdict

The Beyerdynamic DT 660 is a closed-back, circumaural Hi-Fi headphone featuring a wide frequency response of 5 Hz – 32,000 Hz, a 32-ohm impedance for easy driving with portable devices, and a sound pressure level of 97 dB. Known for its sophisticated, neutral sound signature, it utilizes a neodymium magnet system and a proprietary bass-reflex design to deliver detailed bass and clear, brilliant highs. Main advantages include exceptional passive noise isolation of approximately 16 dB, a convenient fold-away design with 90-degree swivelling earcups for portability, and high wearing comfort through padded headbands and soft, replaceable earpads. However, some users note the treble can occasionally sound harsh or sibilant on bright tracks, the overall aesthetic is somewhat utilitarian, and the pivot joints have been identified as potential weak points in long-term durability.
