Surrender to a Relaxed Sound Signature, Exceptional Precision, and Easy Comfort: Sennheiser HD 6602S Open-Back Headphones Feature Extended Sub Bass, Warm Tonality, and Wearability
Warmth, comfort, intimacy, relaxation: These desirable traits are not only the provenance of a spa retreat but the Sennheiser HD 660S2 open-back headphones. Bolstered by a powerful vented magnet system for minimal distortion and a super-light aluminum voice coil with 300-ohm impedance for superb impulse responsiveness, the made-in-Ireland HD 660S2 gives you high-end resolution and balanced playback marked by alluring timbre, accuracy, and detail. Sennheiser also pushes the limits when it comes to sub bass — a feature audiophiles traditionally frown upon. Yet in HD 660S2, it feels expansive and taut. By doubling the sound pressure at the lowest frequencies, HD 660S2 manages extra space, extension, and depth — all the while retaining evenness throughout the audio band.
Weighing barely more than half a pound, HD 660S2 is meant for long-haul listening sessions. Velour earpads and a generously padded headband invite you to slip these ‘phones on your head and keep them there. A 6.3mm cable, 4.4mm cable, 6.3mm-to-3.5mm adapter, and carry patch further the value of this daily driver that Sennheiser further enhanced over prior models with added sensitivity across the entire spectrum and a more efficient magnet air gap. In layman's terms, that means engaging speed, precision, and transparency. What’s not to like? Far as we can tell, there’s no good answer to that question.
