€250 is right on the money for this one — basically at the €251 median and comfortably inside the normal used range.
That makes it a fair buy rather than a bargain, but a sensible one if the set is clean. The HD660S is well liked for its balanced tuning, smooth mids, and easy long-session comfort, so buyers usually get a dependable all-rounder rather than a hyper-technical statement piece. At this price, the main upside is simply getting a respected, low-drama headphone at market value; if pads, cable, and headband are in good shape, it’s a solid pickup.

Founded in June 1945 by Dr. Fritz Sennheiser in a farmhouse near Hanover, Germany, Sennheiser began as Laboratorium Wennebostel, producing voltmeters and early microphones amid post-World War II reconstruction. Seven engineers from the University of Hannover joined the founder, quickly pivoting to broadcast microphones like the DM 2 in 1946 and the groundbreaking MD 82 shotgun mic in 1956. Renamed Sennheiser electronic in 1958, the family-owned company passed to second- and third-generation leadership, maintaining its innovative spirit over eight decades.
Sennheiser excels in professional and consumer audio, renowned for microphones, wireless systems, and headphones that set industry standards. Pioneers of the first open-back headphones (HD 414 in 1968) and enduring studio icons like the MD 421 and MD 441, they also produce high-end headphones, earbuds, soundbars, and conferencing solutions. While strong in pro audio like mixers and geophysical gear, their consumer focus centers on headphones and wireless tech rather than amplifiers, speakers, turntables, DACs, or cables.
Sennheiser commands a premium position in the hi-fi market, blending mid-tier accessibility with high-end excellence for discerning buyers and professionals. Trusted for reliability and sonic precision, it appeals to audiophiles seeking reference-grade headphones without boutique obscurity, backed by a heritage of technological firsts that sustains its global leadership.
