660s = Badass!
Watched a review on these headphones via: Z Reviews. Check him out. I was looking for something I could listen to music with and also game with comfortably. And I believe I have found what I was looking for. They sound fantastic. At 150 Ohm I have them running off of my Topping MX3 with no problems. Waiting my other Headphone amp to show up so I can run these bad boys in Balanced. If you can pick these up for a good price, do it! Read full review

Great cans and excellent purchasing experience.
The headphones arrived quickly and upon inspection, I found them to be almost pristine. After listening to them for the last few days, the cans are great. I had been looking at the Sennheiser entire 600 series for some time and when these 660s cans showed up in my search, the price determined which headphones I would buy. I love them.

Hearing is Believing
These headphones deliver incredibly high quality--or audiophile-level--sound to one's ears. They are seamless with the top-to-bottom frequency range. Dynamics are very good as well. In order to achieve these things, they must be used with very high quality equipment.Read full review

HD660s - An excellent option
My collection of headphones include HD650, HD600, and HD660s. I prefer the HD660s because they are easier to drive and, to my ears, are a little more crisp especially at the higher frequencies. The HD650 are also excellent, but are a little warmer sounding than the HD660s. None of the three are bad choices. Read full review

Large melon
These were a used pair of headphones - sound is great - just the person who own them before must have had a large melon / normality the band is tighter.
Good Deal “o” Neal

My go to cans
Awesome go to headphones! Very strong midrange and clear in all areas. I have other headphones that have more dynamic range but it depends on how I feel like listening to my music at the time and these never disappoint!!Read full review
