SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

These sound ok but I had a pair of Audio Technica at half the price that sound better

Sounds nice with the source from my MacBook pro, but is even better with external DAC & AMP

Buenos pero por lo que cuestan, las almohadillas están horribles, durísimas, por el precio debieron de ser de memory foam con piel.... pero es tela dura. Ademas aprietan muchísimo. El sonido esta muy bueno

I really was excited to get these headphones and wanted to love them but they have a muffled flat sound. My Grado SR60s have a fuller sound and cost about a fourth of what these cost. I am most likely going to send these back.

Are you like me? Does your wife dread looking into the Amazon cart only to see ANOTHER pair of headphones on their way? Well look no further, these are the ones.

having the option of the balanced 4.4mm was great. could be a placebo, but on my ifi hipdac it sounds better than using the 6.35mm jack with the 3.5mm adapter

Probably some of the best headphones Ive ever used. Balanced, clean and accurate.

First Open-back headset... Wonderful

Noise cancellation- yup, he can’t hear me when I yell up the stairs. Perhaps a little too well.

I felt this Sennheiser 660s listening experience compared favorably with my JBL S-38 IIs. I noticed this especially while listening to Aaron Coplands Concerto for Clarinet and String orchestra. Also, I noticed favorable compares with Howard Hansons Symphony #3 in the 2nd movement. In fact, they performed so well, I was momentarily confused whether I was listening to the music on the bookshelves or the headphones.
