SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Product came out like some one used it (picture) and than put it back in the box. For 300+ headphones, you would expect better quality. I think these might be fakes. I havent tried them out yet. DO NOT BUY THESE FROM HERE

Great sound, good build quality, needs an amp to sound loud.

A lot of people tend to criticize these headphones or even compare them to the 650 but IMO there is no comparison. I was actually pleasantly surprised. I love Sennheisers studio headphones but all the negativity behind these made me reluctant. Well dont be, these cans are absolute awesome and so easy to EQ as per your tastes.

Using to listen to music online, as advised.

If you could only own two headphones, these and the dt1990 pros are all that you need. The mids sold me on these headphones.

Primero que nada no soy experto... son mis primeros audífonos de este estilo que compro, estuvo buscando y haciendo research de diferentes modelos, marcas, precios... al final después de mucho pensarlo decidí comprar estos y definitivamente tengo que decir que soy muy feliz...

Very comfortable over long periods. Excellent sound quality.

It has amazing sound quality but this a not for noise canceling feature.

After only a handful of songs, I was in tears. Song I had heard hundreds of times, sounded brand new. Decades of being color blind for using cheap Bluetooth headphone, and “gaming headsets”. Now I can see the rainbow of sound that actually exists.

Ive been using the ATH M50Xs for years now and have loved them immensely however I realized they didnt handle FLAC files properly and made them sound really congested. Wanted a headphones that could reproduce the sound without that congested feel and holy hell the HD660s does just that.
