Sennheiser’s new HD 660 S is the ideal open, dynamic headphone for the passionate audiophile. Meticulously crafted for most demanding listener, the HD 660 S builds on the legacy of the legendary HD 650, surpassing the exceptional performance of its predecessor with a new and improved transducer design that delivers lower harmonic distortion for an even more natural, lifelike audio experience.
It is exceptionally accurate and transparent, yet has an expressiveness that immerses you in every emotion and nuance of music. With a lower impedance of 150 ohms, and a wider choice of cables that includes both balanced (4.4 mm Pentaconn) and 6.35 mm connectors, the HD 660 S offers the versatility to enjoy reference class high fidelity sound with stationary and mobile players alike.
Following the tradition of Elemental Amps, Sherlock is designed for a no-compromise performance at a very affordable price. During the design process, we took further steps to make Sherlock modular and expandable, from a stereo amp to a fully balanced amplifier. We are pleased that we succeeded in producing the Sherlock with unprecedented driving capability and musicality at a very cost-effective price point.
Sherlock’s uniqueness is the added bridged circuits ahead of the main amp. These circuits when activated converts input signals into balanced (positive plus negative polarities) format and feeds to the left and right channels. This special design feature turns a tandem pair of Sherlock into a truly stereo balanced amplifier.
Sherlock is the first bridgeable headphone amplifier and audiophiles can enjoy the single chassis first and subsequently upgrade to double chassis for balanced performance. The audiophile with their numerous headphone collection will find the Sherlock to be a timeless investment.
