Rarely used for half year, pair of Sennheiser HD 660S2 open-back audiophile headphones. Legendary 600 series sound with extended sub-bass, natural mids, and wide soundstage. 300Ω impedance – ideal for hi-fi amps/DACs. Premium velour pads for long listening comfort. Includes: headphones, detachable cable, original box/packaging. Selling as I'm already upgraded for Neumann NDH-30.
