Sennheiser HD 660S2 Open-back wired over-ear headphones
sku# 143HD660S2
High-grade 38mm soft diaphragms with steel mesh damping material and vented magnet system for clean, low-distortion sound. Iconic headphone design with an updated sound tuning Meet the newest version of Sennheiser's legendary "HD 600" series. The HD 660S2 headphones sport a similar look and feel to their predecessors , but offer some sonic tweaks. From early listening impressions - and my time listening side-by-side with older "600" models at CanJam NYC - I enjoyed the deeper bass extension and slightly larger soundstage.
