Sennheiser HD 660S2
2 of the 10 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
