Choosing between them depends largely on your listening preferences and setup.
Verdict
The Sennheiser HD 660S2 is the better choice for audiophiles seeking balanced, detailed sound, excellent comfort, and a more natural listening experience. Its open-back design and high impedance make it best suited for dedicated headphone amplifiers and home listening. The Sony MDR-Z7M2 is better for listeners who prefer stronger bass, wider frequency extension, and easier compatibility with portable audio gear. For pure sound accuracy, the HD 660S2 takes the lead, making it the overall winner.
