When it comes to high-quality audio and exceptional headphone design, few brands are as synonymous with excellence as Sennheiser. With decades of experience in creating premium audio equipment, Sennheiser continues to set the bar for audiophile headphones. One of their standout models in recent years is the Sennheiser HD 660 S Open-Back headphones, a successor to the highly praised HD 600 series. These headphones offer an extraordinary listening experience, combining impeccable sound quality, comfort, and design.
The Sennheiser HD 660 S has been crafted with audiophiles in mind, delivering a perfect balance of detailed sound, powerful performance, and a comfortable fit for long listening sessions. In this article, we’ll dive into the features, sound profile, and why these open-back headphones are a must-have for serious music lovers.
The Design and Build of the Sennheiser HD 660 S
The Sennheiser HD 660 S Open-Back headphones are designed with both performance and comfort in mind. Building on the foundation of the iconic HD 600, the HD 660 S features a refined design, making it not only an audiophile-grade product but also a comfortable option for prolonged listening.
The open-back design of the HD 660 S offers a more natural, spacious soundstage, creating an experience that mimics listening to live music. This open-back construction allows sound to flow freely in and out of the headphones, which results in a more open, airy, and accurate sound profile. This is especially important for critical listening, where the distinction between different instruments and subtle audio cues can significantly enhance the listening experience.
The build quality of the HD 660 S is also top-tier. The ear cups are made from a durable yet lightweight material, ensuring that the headphones are comfortable to wear over long periods without feeling too heavy on the head. The headband is padded, providing an additional layer of comfort, while the ear cups feature soft ear padding that creates a secure and comfortable fit, isolating external noise to some extent.
Another noteworthy feature is the detachable cable, which offers more flexibility and durability than non-detachable cables. It also ensures that the headphones can be easily replaced or upgraded in the future. With a standard 6.3mm stereo plug, the HD 660 S is compatible with a wide range of audio devices, although an amplifier is recommended to achieve optimal sound quality.
Unmatched Sound Quality: What Makes the HD 660 S Stand Out?
The sound quality of the Sennheiser HD 660 S Open-Back headphones is where they truly shine. Known for their exceptional balance and clarity, these headphones deliver a sound signature that is both detailed and natural, with a wide soundstage that allows you to hear every nuance of your favorite music.
Soundstage and Clarity
One of the key features of open-back headphones like the HD 660 S is their ability to create a more immersive and expansive soundstage. The open-back design allows sound to flow naturally, creating a sense of depth and width that closed-back headphones often struggle to replicate. The result is a sound profile that feels like you’re in the same room as the musicians, offering a more organic and authentic listening experience.
The clarity of the HD 660 S is exceptional, with every note, instrument, and vocal rendered with precision. The headphones provide a perfect balance between bass, midrange, and treble, allowing for accurate reproduction of a wide variety of music genres. Whether you’re listening to classical music, jazz, rock, or electronic, the HD 660 S can handle any genre with ease, delivering crystal-clear highs, detailed mids, and a punchy, controlled low end.
Bass Response
While open-back headphones are often known for having lighter bass response compared to closed-back models, the HD 660 S provides a bass profile that is both balanced and natural. The bass is not overpowering but is rich and present, providing a solid foundation for the rest of the audio spectrum. The low frequencies are tight and well-controlled, ensuring that they don’t muddy the mids or highs.
Midrange Performance
The midrange is where the HD 660 S truly excels. The headphones have a remarkably accurate and smooth midrange that brings vocals and instruments to life. Whether you’re listening to a female singer’s delicate voice or the nuances of an acoustic guitar, the HD 660 S delivers a rich, full-bodied sound that captures the essence of the performance. This makes the headphones ideal for genres like jazz, classical, and acoustic, where midrange clarity is paramount.
Treble Precision
The treble performance of the HD 660 S is detailed without being harsh or sibilant. The highs are crisp and clear, with a natural sparkle that adds airiness to the sound. This precision ensures that cymbals, strings, and other high-frequency elements are reproduced with lifelike detail, adding to the overall realism of the audio.
Comfort for Long Listening Sessions
One of the standout features of the Sennheiser HD 660 S Open-Back headphones is their comfort. Designed for audiophiles who often listen to music for hours at a time, the HD 660 S ensures that long listening sessions are enjoyable rather than fatiguing.
The lightweight design and comfortable ear padding allow for a secure fit without feeling tight or causing discomfort. The ear cups are large enough to fully encompass your ears, providing an effective seal that keeps out some external noise while also allowing the sound to flow naturally from the open-back design. This makes them ideal for critical listening, where comfort and sound quality are both paramount.
Amplification Needs and Compatibility
While the Sennheiser HD 660 S headphones are highly efficient, they still benefit from amplification to reach their full potential. These headphones are designed with audiophile-grade components, and to truly appreciate their sound quality, it’s best to pair them with a high-quality headphone amplifier or a dedicated DAC (digital-to-analog converter). The combination of a powerful amplifier and the HD 660 S will allow you to experience the full depth, clarity, and range of the headphones.
The 6.3mm stereo plug on the HD 660 S allows it to be compatible with most home audio setups, including many high-end portable devices. However, for the best possible listening experience, investing in a dedicated headphone amplifier or DAC will allow you to unlock the full potential of these open-back headphones.
