HiFiMAN Sundara vs Sennheiser HD 660S2

This matchup represents one of the most exciting debates in the audiophile world, the speed and transparency of planar magnetic technology against the musicality and naturalness of a refined dynamic driver. The HiFiMAN Sundara uses a thin diaphragm suspended between magnets that moves with extraordinary precision, resulting in a sound that reveals layers of detail you never knew existed in your favorite tracks. Fast percussion sounds crisp, guitars have realistic bite, and the soundstage stretches out impressively wide. The Sennheiser HD 660S2 uses a more traditional driver but tunes it with decades of accumulated wisdom, creating a presentation that is warm, inviting, and endlessly listenable without ever sounding boring. Vocals through the Sennheiser have an intimacy that makes unplugged sessions and jazz recordings feel alive and present. Comfort goes to Sennheiser with its lighter build and gentler clamp, though the Sundara is hardly uncomfortable. For pure sonic excitement and value, the Sundara is hard to beat, but for headphones that make you fall in love with music itself rather than analyzing it, the Sennheiser is magic.
