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.

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!

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.
