Amazing imaging

Love this headphone. Fast sound and excellent imaging for gaming

Amazing sound and details

Best sounding headphones I've tried so far. They are built very well and they are nice and light, making them quite comfortable. Clamp force is pretty high at first but that should ease off after more use :)

Good product

Love the sound, the quality, the looks, happy with the hd660s

Absolute gem of an headphone !

Bought these as refurbished headphones, received them looking brand new. Has a bit of clamp but nothing that wont break in overtime. Sound quality, these are a step higher from my 560s in pretty much every aspect. So far, ive tried hd599SE > hd560s and now > hd660s, these are so far my favorite!


The build quality is great and the design is modular, the HD6* series as a whole is my favourite product line. Each of the iterations has something special to them that makes them worth owning, you can feel that it was designed with care that has stood the test of time.
