#1 overall
Sennheiser HD 650 (also sold as Drop HD 6XX)
25 of the 107 comments naming both come from people who say they own this one.
What owners love
- The single most-recommended headphone across every forum read: warm, smooth and easy to listen to for hours
- Scales with better amps; several owners run it on expensive tube amps and say it keeps up
- Female vocals and mids that owners describe as amazing
- The Drop HD 6XX version sold for $199-220 for years, which made it the default first audiophile headphone
The complaints
- Needs an amp; from a phone it sounds flat
- No real sub-bass
- Clamp is tight on big heads
- Some find the slight bass tilt less balanced than the HD 600; soundstage is small

#12 overall
Sennheiser HD 660S2
17 of the 107 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
In their words
“Love my hd660S, couldn't imagine switching to anything else but the 660S2”
