Sennheiser HD 660 S Audiophile Headphones
The perfect blend of power and control, the HD 660S is a powerhouse open-back headphone with the versatility to connect you to the deepest corners of your music collection.
➦ A Direct Connection To Your Music
Known for their engaging signatures and liquid-smooth response, HD 660S predecessors HD 650 and HD 600 shattered performance barriers in the audiophile headphone category. The HD 660S transcends the best of that storied DNA with supernatural speed and effortless instrument reproduction—even at the bookends of the frequency spectrum. Utilizing an all-new transducer and specially ventilated drive unit, the HD 660S delivers the revealing, tack-sharp detail audiophiles demand without sacrificing the engaging dynamics that make music so enjoyable.
➦ From Our Ears To Yours
In just one listen you will understand why the HD 660S is so special. Thousands of listening sessions later its purpose is even clearer. What you hear each and every time is the result of an open-back earcup mated to a new transducer tuned for the modern audiophile. Its speedy response is perfectly suited for reproducing those frequency-stretching recordings with confidence. Thanks to an aluminum voice coil, the 38mm diaphragm remains nimble for ultra-quick impulse fidelity across the board. This activation and rest behavior unlocks the capability to communicate tonal and spatial characteristics precisely.
➦ Capability, Meet Versatility
Today’s audiophile has more component choices than ever. We optimized the HD 660S for efficiency on a wider range of devices to accommodate the varying levels of power present in output amplification circuitry. At 150 ohms, the HD 660S is the perfect partner for dedicated amplifiers, A/V receivers, and audio interfaces alike—the magnet is more powerful than its predecessors, and thus easier to drive regardless of how your setup changes over time.
➦ Handled With Care
Every HD 660S we produce has experienced a matching regimen to mate each transducer from our Ireland manufacturing facility to its opposite-channel counterpart. 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. We designed it with thoughtful, lightweight materials invisible to the acoustical system without sacrificing the durability needed for daily, all-day use. With a never-ending supply of music to consume, we wanted every touch point to be soft, luxurious, and durable for those extended listening sessions.
