SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

The steel band on the top clamps the ear pieces too tight on my head. Who cares about sound quality if they are uncomfortable?

I use these on my gaming pc. I have an audio out that i hooked up to a headphone amp and it works well. The sound I can hear in the game is amazing and helps with sit rep. Def worth the money

Comfortable. I expected a bigger sound. Better for low ranges, but not enough mids and highs

Great quality headphones! The clarity and mids are solid. I connected mine to a SoundBlasterX G6 for gaming and honestly I’m blown away by these. I hear every little footstep and reload noise. Fantastic!

Nice brand of headphones! Few thinks im disagree with- first the package cardboard come damaged, inside box the foam protecting the item looks an feeling chip and human hair on drivers pads and the protecting foam around!

An incredible reference headphone. Slightly lacking in treble but responds very well to EQ.

These sound amazing, plain and simple. Everything from vocals to instruments make it sound like youre in the room with the artist. I paired this with a FiiO AMP/DAC, and it did enough to boost everything to an enjoyable level. Although the jump from a pair of Audio Technica M50x or Bose QC35 ii, is something you really need to determine for yourself, but it wasnt enough for me at a 500$ price tag. The amazing separation of vocalists and instruments was something that I had never experienced and was very tempted to keep them for that reason alone. I might purchase them again in the future when I can rationalize the purchase, but they just did not hit that next level I needed for me to rationalize the purchase. If you have the money, please try them for yourself, you will probably end up keeping them.

In fact, I was not impressed with the sound because I was a person whose discrimination against sound was lower than usual.,When I went out, I used earphones and used them very often at home, so I did not have to write a review.,Why you use expensive products.

The 150ohm impendence makes the 660S much easier to drive then 600/650, it has a typical Sennheiser rich and warm sound signature. Im using the balanced output of Fiio M11 to drive my 660S and it sounds amazing. The sound stage is smaller than 600/650, thus you can feel the intimacy between the singer, especially female vocals. The base is rich and warm, but in decent amount, and does not overpower the treble.

Went from HiFiMAN Sundara, to Beyerdynamic DT1990 Pro, to Sennheiser HD 660 S.
