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.
