Open-Back Design
Headphones with an open-back design, allow air to pass through the earcups. This means that Open-Backs do not block any noise from around you, as closed-backs do, and music being heard will also leak outside to people around you. So they can only be heard in a quiet environment.
However, Open-back headphones do sound more natural and open. Open-back headphones create a feeling of space, presenting audio as if you are sitting at a live concert. Audiophiles swear by open-back headphones, and they sound quite different to closed-backs.
These headphones are perfect for critical listening sessions, mixing and mastering music. They have an accurate soundstage presentation and precise imaging.
Replaceable Cables
A pair of headphones with a replaceable cable has many benefits, and one of them is if the connecting cable has a problem, it doesn’t mean that you have to buy a new one. If the connecting cable gets pulled or damaged, you can replace it and keep using your good-old headphones or IEMs. This way, your headphones will be protected and will last longer. With the advancements in cable manufacturing, you now get a variety of replacement cables with various termination options, lengths and quality.
Needs Amplification
Headphones and IEMs require a certain level of power to sound their best and work at their full potential. When your headphones or IEMs are underpowered, they can sound thin or muffled.
Amplifiers are required to provide adequate power to your headphone or IEMs to perform at their best. Simply put, amplifiers allow a weak audio signal to be boosted to a powerful one.
To put it into perspective, devices such as your phones and laptops come with an amplifier, but they offer very limited output power. This output may not be sufficient to power headphones and IEMs to shine at their best. This is where a dedicated amplifier is required to deliver adequate power to hear your music in all its glory.
The Sennheiser HD 660S2 provides an effortless listening experience. If you have a preference for acoustic or vocal-focused music, these over-ear headphones are likely to satisfy your tastes. The quality of the midrange alone might be enough to make the purchase worthwhile, but what distinguishes them is the notable bass presence, making them a compelling option for an upgrade.

DESCRIPTION
PRESENTING THE ALL-NEW HD 660S2, A DEFINITIVE UPGRADE TO THE LEGENDARY HD 660S
Sennheiser has a 75-year history, past achievements, and inventions in the audio industry as a third-generation family-run company, as well as its desire to influence its future. Sennheiser's engineers work diligently to provide some of the most audiophile-focused headphones available. The manufacturing process for headphones like the HD 600, HD 650, HD660S, HD 800 S, and HD 820, to mention a few, involved extensive research and development. With the same approach, the HD 660S2 was born. The new, high-end Sennheiser HD 660S2 headphone outperforms the iconic HD 660S's excellent performance. Sennheiser is attempting to expand its product line with the HD 660S2, designed specifically for the most demanding listeners. An eye-catching new matte black design is featured on the Sennheiser HD 660S2. It has a classically exquisite appearance with some modern influences. It truly represents sophistication with the text and logo having bronze colour. The HD 660S2 headphones provide an audiophile-grade experience that will take your breath away!
FEATURES 38MM DYNAMIC TRANSDUCERS THAT DELIVERS BREATHTAKING SONIC PERFORMANCE
Sennheiser has reduced the transducer size on the HD 660S2 having the all-new 38mm transducer. The HD 660S2 has an extended sub-bass response compared to the HD 660S. It offers a relaxed sound signature with non-offensive tuning, allowing you to listen to your favourite tracks at a stretch. It has exceptional resolution taking you closer than ever to instruments and vocalists. The sound is relatively balanced across the frequency spectrum that does not lead to fatigue if listened to for long hours. The HD 660S2 has a warm and inviting signature combined with extended sub-bass making listening uniquely pleasant and rewarding. It practically begs you to keep going for endless sessions. That’s how HD 660S2 combines the best of both worlds combining non-offensive tuning and optimum comfort. The HD 660S2 gives you an extraordinary experience, allowing you to immerse yourself in music. Dive deeper into the legendary sound of the HD 660S2!
OPEN-BACK DESIGN OFFERS AN EXPANSIVE SOUNDSTAGE AND PRECISE IMAGING
High-end Sennheiser headphones have inspired generations since the HD 580 because of their balanced, natural reproduction. The HD 600, HD 650, and HD 660S all share audible and visual characteristics with the HD 660S2 and are industry standards for neutral audiophile sound. For instance, the HD 660S2 has an updated coil which now matches the renowned HD 600 and HD 650 300-ohm impedance. Moreover, this redesigned coil offers improved electrical damping and magnetic force for an impactful impulse response. The HD 660S2 has significantly better accuracy, responsiveness, and resolution and twice as much sound pressure at the lowest frequencies. Sennheiser has retained extraordinary precision and balance throughout the sub-bass, mid-bass, and beyond. Most impressive is how this affects the listening experience. Extension on the low end changes everything — by creating more space for the sound. Against a deeper backdrop, highs feel more brilliant, the soundstage deeper and open, and emotions stronger with precise imaging. Experience an oasis of sonic bliss with the all-new HD 660S2!
EXQUISITE DESIGN WITH ALL-DAY WEARING COMFORT
The Sennheiser HD 660S2 is built entirely in Ireland and quickly grabs your attention due to its excellent build quality. The HD 660S2's velour earpads can only be described as a physical delight. The headband won't detract from your music thanks to its soft padding and just-right tension for optimal acoustic alignment. The HD 660S2's open-back design provides an incredibly comfortable environment, even during prolonged sessions. The ergonomic headband and lightweight design rule out any potential discomfort on top of your head. You'll rapidly develop an attachment to a listening experience as physically relaxing as the pleasant, non-fatiguing sound at its core.
EASY CONNECTIVITY WITH HIGH-QUALITY CABLES THAT ENSURE LOSSLESS SIGNAL TRANSMISSION
Sennheiser is known for designing some of the most versatile cables that are robust and provide exceptional audio transmission. Sennheiser has included two sets of beautiful cables with the HD 660S2 to accommodate your audio configuration. It has no microphonics and achieves a stable connection. The package includes a 6.3mm (Single-Ended) cable and a 4.4mm (Balanced) cable with 1.8m in length, making them compatible with most audio sources. One benefit of using the HD 660S2 with a balanced connection is that it offers an even lower noise floor and excellent dynamic range. The result is a broader soundstage, precisely controlled transients, and impossibly distinct instrument separation.

Read More"In a word, the sound is effortless. It just springs forth and gently bathes you in its detail, instead of pummeling you, which is a possible side effect of closed-back headphones. "
Read More"The S2 has smooth and delicious treble for high hats and higher pitched instruments. It's done completely different compared to the 600, 660S and 560S. And it's realism."
Read More"The S2 does make its case with the improvements in the sound signature. The soundstage depth is an improvement, but the bass and treble also undergo enhancement."
Read More"Plush earpads and cushy headband padding place the revised 300-ohm transducers at optimal distance from the ear resulting in a spacious soundstage with abundance of detail."
Read More"The coil matches the 300-ohm impedance of the HD 600 & HD 650. This new coil provides higher magnetic force and electrical dampening for cleaner impulse response."

This headphone is a classic. The Sennheiser HD650 isn't a new headphone, but it's still a favourite amongst audiophiles. The sound signature can be best described as 'reference grade' because so many people over the years have used this as a benchmark for use in the studio and at home. Pair it with a decent tube amplifier to hear it sing.
