THE DIFFERENCES, MADE VISIBLE

Visual facts

Differences first. Select a topic for its graphic, sources and conditions.

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.
FEATURES SIDE BY SIDE8 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

Cable length

Manufacturer-stated cable length. Check whether it is straight or coiled and whether the cable detaches; equal length does not mean an identical connection.

Explore the full specifications

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Beyerdynamic DT 1770 PRO MKII

What it brings

  • The closed design has a rated ambient noise attenuation of 25 dBA, and beyerdynamic describes the headphones as ideal for professional studio and monitoring applications.
    Manufacturer source
  • Two ear-pad sets change the tuning: velour with a slight bass boost, or leatherette for a linear response; beyerdynamic states that almost every part of the headphones can be replaced.
    Manufacturer source Manufacturer source

What to check

  • beyerdynamic rates it at 377 g without cable and a nominal headband pressure of 6 ±0.5 N; anyone sensitive to weight or clamping force over long sessions should weigh these figures.
    Manufacturer source Manufacturer source
  • Isolation is passive only and there is no microphone, so it is not a substitute for active noise-cancelling travel headphones or a headset for calls.
    Manufacturer source Manufacturer source

Beyerdynamic DT 1990 PRO MKII

What it brings

  • Two velour ear-pad sets are supplied: 'Producing' with a slight bass boost and 'Mixing & Mastering' for a linear response, so the tuning can be changed by swapping pads.
    Manufacturer source
  • beyerdynamic states that almost every part of the headphones can be replaced, including the headband and ear pads, and the single-sided mini-XLR cable is detachable and can be locked.
