#8 overall

Beyerdynamic DT 990 PRO (250 ohm)

6 of the 12 comments naming both come from people who say they own this one.

What owners love

  • Wide, open soundstage with sharp imaging; owners who came from gaming headsets call it a revelation
  • Very comfortable velour pads; owners keep them for 5-7 years
  • Built like the DT 770 and repairable: pads, headband and cable are replaceable

The complaints

  • The treble: bright to sharp, the most repeated complaint of any Beyer; some EQ it down
  • Bass is present but not deep
  • 250 ohm version wants an amp; the Pro X or 80 ohm editions are easier to drive
  • US service and repair experiences are poor

In their words

#12 overall

Sennheiser HD 660S2

4 of the 12 comments naming both come from people who say they own this one.

What owners love

  • Vocals and mids: owners who compared it with the Sundara and DT 1990 give it the win on voices
  • Smoother, less fatiguing than bright rivals; long sessions without ear pain
  • Large cups that fit big ears; light for hours of use
  • The S2 adds the bass the original 660S was criticised for

The complaints

  • Bass is still modest next to planars
  • Some units creak
  • Price: owners often call it a little overpriced against the HD 600/650 or the 58X
