Excellent Condition, Complete with Original Box and Accessories: SENNHEISER HD 660S2

This is the highly acclaimed open-back headphone HD 660S2 from Sennheiser.
Its musical, beautiful, and fatigue-free sound captivates many audio enthusiasts.

▼ Appeal of this Headphone
The low-frequency reproduction has dramatically improved from the previous model, deeply and realistically rendering everything from the resonance of a jazz double bass to the impact of a rock kick drum.
