Sennheiser HD 660S2 Open Back Headphones

The HD 660S2 is the newest version of Sennheiser's legendary "HD 600" series. They feature the same iconic design as their predecessors but with some noticeable sonic tweaks, in particular to enhance the lower bass frequencies with the 660S2’s now dropping down to 70Hz.

Musical Precision

Like their predecessors, the HD 660S2 headphones are crafted for the discerning listener. Each speaker is hand-selected and meticulously paired to ensure consistent sound quality across both channels. The precision-engineered stainless-steel diaphragms deliver an incredibly realistic, true-to-life audio experience.

Open-Back Design for Expansive Sound

With an open-back design, the HD 660S2 headphones provide a wide, more natural, airy sound, getting you as close to a live performance as possible.

Balanced Input Capability

Equipped with both balanced and unbalanced cables, the HD 660S2 optimizes the performance of high-quality headphone amplifiers and audio players with balanced outputs. Balanced cables reduce interference, preserving the purity of the sound. The standard cable features a 6.35mm plug, with a 3.5mm adapter included for convenience.

Built for Comfort

When audio quality is this exceptional, extended listening sessions are inevitable. The HD 660S2 ensures lasting comfort with its ergonomic, elliptical ear cups that naturally conform to your ears. The breathable, soft earpads enhance comfort without becoming sticky or uncomfortable during long use.

Pretty pathetic spoons, fantastic price to quantity ratio
Size: 1000 Teaspoons
Weak, not very rigid. But you can't beat the price or quantity! Don't serve these at a party, you will be made fun of.
