Sennheiser HD 660S 2 - Wired Audiophile Stereo Headphones with Deep Sub Bass, Optimized Surround, Transducer Airflow, Vented Magnet System and Voice Coil

I'm totally satisfied with the headphone. Well built and comfortable to wear. The vivid sound stage and meticulous details of replayed music are highly enjoyable. Not strong in dynamics but the beautiful music, particularly of jazz and vocalist, more than makes up for it.

Nearly every review I have read and YouTube video I have watched has told me that the 600's and 650's are superior to the newer 660s2's despite their age, so I believed them and bought some 650's. Yes they are exceptional cans and deserve their legendary status, but curiosity got the better of me and decided to try the 660s2's. Granted I'm no expert, but I think the 660s2's are better headphones in every single department. Ever so slightly more comfortable, a smidge more bass, a tad more detail, a bit wider soundstage and a more modern, stylish paint job. I think they are a step forward, not by much, but how could they be? Sennheiser shot themselves in the foot all those years ago by setting the bar so high.
