one of the most excellent open backs ever made, gets a bit of Sub-bass extension at the cost of a dip in the 3-4kHz range for a wider soundstage with a hint of placebo effect. Overall, its really hard to improve an already 20+ year design, nonetheless Senheisser spent the time and continues to innovate even if its laterally rather than forward.

The best of the 600 series
I have the 600, 650 and the 660s. The 660s2 has the most complete balanced audio. It fits well. I use for all types of music. The 660s2 is an excellent headphone for audiophile sound. You don’t need another headphone.

The sound of these is the best I've heard from Sennheiser in quite some time. These are really nice. The headband is part metal so you can bend it how you like to make these super comfy. Fantastic sound!!
