What customers say about "Size & Weight"
 
Sennheiser HD 660S Over-Ear Open Dynamic Headphones - Black
  • I am amazed! Sennheiser 660s are so light, versatile and fits perfectly on the head.
  • Very comfortable, super lightweight. If you are worried about the clamp, don’t be. Psb and Nad headphones are way worse and people still like them. Extremely natural sounding.
  • For the rest, comfortable, really light weight and the sound is really great.
  • These headphones are a good fit - slightly tighter than some, but not to the point of being an irritation - and while they are solid and well built, they aren't heavy enough to feel uncomfortable.
  • The headphones themselves are light and comfortable - quite large and covering the ears fully.

What customers say about "Features"
 
Sennheiser HD 660S Over-Ear Open Dynamic Headphones - Black
  • Your ears are breathing, you cannot overheat your ears while wearing those headphones.
  • Comfort-wise I have no issues. It’s a solid but comfortable/immersive fit.
  • They are a comfortable fit over the ears (I have been using in ear phones for the past decades) and do look rather trendy ~ thank you designers!!
  • The fit is very comfortable over the top of my head with just the right amount of pressure to hold the cans over my ears.
  • Fantastic headphones, certainly the best I’ve used! The keyword for me is – revelatory. Using them to listen to FLAC music both on my mobile and laptop is a very rich, immersive experience.
