OPEN-BACK DESIGN OFFERS AN EXPANSIVE SOUNDSTAGE AND PRECISE IMAGING

High-end Sennheiser headphones have inspired generations since the HD 580 because of their balanced, natural reproduction. The HD 600, HD 650, and HD 660S all share audible and visual characteristics with the HD 660S2 and are industry standards for neutral audiophile sound. For instance, the HD 660S2 has an updated coil which now matches the renowned HD 600 and HD 650 300-ohm impedance. Moreover, this redesigned coil offers improved electrical damping and magnetic force for an impactful impulse response. The HD 660S2 has significantly better accuracy, responsiveness, and resolution and twice as much sound pressure at the lowest frequencies. Sennheiser has retained extraordinary precision and balance throughout the sub-bass, mid-bass, and beyond. Most impressive is how this affects the listening experience. Extension on the low end changes everything — by creating more space for the sound. Against a deeper backdrop, highs feel more brilliant, the soundstage deeper and open, and emotions stronger with precise imaging. Experience an oasis of sonic bliss with the all-new HD 660S2!

EASY CONNECTIVITY WITH HIGH-QUALITY CABLES THAT ENSURE LOSSLESS SIGNAL TRANSMISSION

Sennheiser is known for designing some of the most versatile cables that are robust and provide exceptional audio transmission. Sennheiser has included two sets of beautiful cables with the HD 660S2 to accommodate your audio configuration. It has no microphonics and achieves a stable connection. The package includes a 6.3mm (Single-Ended) cable and a 4.4mm (Balanced) cable with 1.8m in length, making them compatible with most audio sources. One benefit of using the HD 660S2 with a balanced connection is that it offers an even lower noise floor and excellent dynamic range. The result is a broader soundstage, precisely controlled transients, and impossibly distinct instrument separation.
