Sitting here listening to Quincy Jones, Back On The Block, an album which you’d expect to sound better on the HD660S than the HD650 if ever there was one! And, it does!
Im using my iPod / Fostex HP-P1 set up. The differences could be less obvious on a better amp, but there’s no doubt that on that gear it’s all the Hd660S’s way! I previously described the HD650 as ‘soft and muddy’ sounding by comparison. I would actually want to retract the ‘muddy’ adjective. To be honest I’ve never found the (my) HD650 to be muddy, but I think ‘soft’ sounding is a good description and I might go so far as to say a bit ‘mushy’ at times by comparison. Initially the HD650 always sounds more pleasing in some ways, but I consistently find that the sound becomes a bit boring fairly quickly whereas the HD660S, whilst sounding somewhat dryer, and yes, I would say more neutral, sounds more interesting and involving the more one listens.
This is nothing new, I know, having been reported in a similar way by many people here, but I thought I’d add my two cents!
Really enjoying rediscovering a lot of music that I’ve had no insensitive to listen to for a long time!
To me it’s the HD 650 growing a bit boring overtime is why I often let go of them in the past. The HD 660 S on the other hand was one of the most addicting headphones I’ve owned in the long run, one of the only other headphones I found that addicting would be the T1.2. Most everything else is kinda boring to listen to after a headphone that is high on the engagement factor. It’s hard to pin down exactly what makes a headphone involving and addicting to listen to, but I find it special when a headphone has it.
