Works perfectly.

Minor cosmetic damage (paint chips on metal ear ups)

No dents or cracks.

Recently put on new earpads and used new earpads only a couple of times.

It comes with 1/4" to 3.5mm adapter.

I unfortunately don't have the original box so it will come in a plain box.

In just one listen you will understand why the HD 660S is so special. Thousands of listening sessions later its purpose is even clearer.

What you hear each and every time is the result of an open-back earcup mated to a new transducer tuned for the modern audiophile. Its speedy response is perfectly suited for reproducing those frequency-stretching recordings with confidence. Thanks to an aluminum voice coil, the 38mm diaphragm remains nimble for ultra-quick impulse fidelity across the board. This activation and rest behaviour unlocks the capability to communicate tonal and spatial characteristics precisely.
