Taking inspiration from its predecessors, the Sennheiser HD 660S is here to break performance barriers with its smooth transient response and engaging sound across the frequency range. The new driver unit and spaciously stunning mesh ensure a dynamic sound with every detail intact. The multiple cables and connector options make this the perfect audiophile go-to.
Unlock the Perfect Tone & Space
The perfect blend of an open-back design with a specially-tuned driver, the Sennheiser HD 660S is designed for the modern audiophile. Its aluminium voice coil and 38mm diaphragm is ultra-quick for a fast transient response across the frequency range. Each driver is matched to its opposite-channel counterpart at our manufacturing facility in Ireland. These tolerances are extremely narrow and when bolstered by automated assembly processes, ensure that your HD 660S experience is consistent with those all over the globe.
Beautiful & Functional
The HD 660S was engineered with a thoughtful acoustical system. It is crafted from light and durable materials for a luxurious feel. The steel mesh on the earcups is intricately designed to look gorgeous while acting as ventilation for the driver, offering consistent control of air displacement to reduce turbulence. The result: Each note is spacious, natural and beautiful.
Versatility that Brings Out the Best in Your Music
No matter the audio source device of your choice, the HD 660S is geared to make it shine. Sennheiser has included multiple 3-metre (9.8-feet) long cables with a variety of connectors. The ¼-inch (6.3mm) stereo plug is the standard connection for audiophile devices like headphone amplifiers, A/V receivers, DAPs, computer-based workstations, etc. A 4.4mm connector is perfect for audio devices with a balanced output. Need something for on-the-go sound? The 6.3mm to 3.5mm adapter is here to the rescue.
