Feeling for the sound is an understatement. You can feel it flowing through your body when you slip on a pair of Sennheiser HD 660S headphones because these are engineered to deliver power and control in perfect measure. With an open-back design for subtle definition between low notes and high ones without ever sacrificing detail, these headphones will allow you to become more engaged with all of the energy that’s put initially into your favourite songs.
The next best thing
Rigorous engineering and unrivalled German precision go hand-in-hand at Sennheiser. This holds true for the HD 660S, which was improved using an all-new transducer and specially ventilated drive unit to deliver the revealing, tack-sharp detail audiophiles demand while still delivering natural sound reproduction that leaves listeners speechless.
The HD 660S transcends previous models with supernatural speed, effortless instrument reproduction. It’s the world’s first audiophile headphone that delivers revealing detail without sacrificing sound engagement.
Open the new sound quality
With the HD 660S, you will be able to enjoy music with an entirely new level of immersive clarity. Crafted by iconic musicians for listeners who demand the very best, these headphones are engineered for incredible speed that delivers instrument textures with breathtaking realism. So grab your favourite album or playlist and start discovering your perfect sonic signature.
With the HD 660S headphones, it’s like music is playing right next to your ear—but only softer, less obnoxious headphone-listener separation. Sennheiser’s first open, dynamically transparent full-size headphones for studio use are perfect for detailed work in noisy environments where you need both direct and reflected sound. They offer an excellent natural balance, excellent clarity of fine detail (such as small nuances that differentiate two violins), and all the benefits of an open design: more spacious frequency response with considerably improved imaging quality.
A perfect match for those seeking a natural sound with a touch of added style. A headphone designed to bring out your inner audiophile and satisfy even the most demanding and easy listening listener.
Designed for demanding listeners looking to take their listening even higher, the device is perfect for open-back design lovers who still crave a closed-back construction.
The new 38mm driver with an aluminium voice coil provides frequency extremes of an open-back earcup combined with the impulse fidelity of a closed-back model. In both wired and wireless versions, these exceptional headphones take your listening experience up a notch.
They also bring together steel mesh that does an excellent job of ventilating any sound coming from the headphones so you can hear every note as it should be heard without added turbulence. In other words, they’ve got everything under control!
Versatility at its finest
Meet the ultimate all-around headphone. The HD 660S is the perfect match for any “power-hungry” audio gear you might have. It also features a balanced armature technology that helps to reduce distortion and pitch variation at all frequencies with its wide dynamic range of 10 Hz-40kHz so that every note will be heard.
The HD 660S is perfect for all your connected listening needs. With a balanced, 4.4mm headphone connector to the new generation of devices with selectable outputs, this set can accommodate them all! A one-quarter inch 6.3 mm stereo plug? Yes, please!
You will receive multiple types of cords just in case you need it! Rest assured that each cable in the package was impedance-matched so you could stay true to your headphones expectations without added highs or lows from being unable to connect through a faulty cord. The world is more connected than ever before, and we want you to enjoy everything interconnected music has to offer, so don’t keep yourself away from anything Sennheiser has on tap with these babies!
