#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

#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
