Sennheiser HD 660 S Open-back wired over-ear headphones
A classic revisited: Many of us here at the company credit Sennheiser's legendary "HD 600" series as our gateway into the world of truly high-end personal audio. These HD 660 S headphones keep the spirit of their stellar predecessors alive (and we recently ranked them one of our " Top 5 most comfortable headphones "). They feature a tweaked design and completely revamped driver system. The HD 660 S headphones features velvet-soft ear pads and hold into place without squeezing too tightly.
