Best For
The Sennheiser HD 700 and HD 660S2 are both open-back wired headphones designed for serious listening, but they take different approaches to sound. The HD 700 uses a 150-ohm design with a wide 8 Hz–44 kHz frequency response and is tuned for a spacious, warm and balanced presentation. The HD 660S2 uses 300-ohm impedance, 38 mm dynamic drivers and emphasizes intimate sound with deep, accurate sub-bass. Both are lightweight and designed for long listening sessions, while the HD 660S2 also includes multiple cable options and a carry pouch. Your choice largely depends on whether you prioritize a wider soundstage or richer low-frequency performance.
Verdict
The Sennheiser HD 700 is better suited to listeners who value a spacious soundstage, detailed stereo presentation and an airy open-back experience. The HD 660S2 is a better fit for users who prefer a more intimate presentation with stronger, more controlled sub-bass and flexible connectivity through its included cables. For classical, acoustic and spacious recordings, the HD 700 has an appealing design, while the HD 660S2 is particularly suitable for modern music where low-end detail matters.
