What customers say about "Size & Weight"

KEF M400 Over-Ear Hi-Fi Headphones - Champagne White

It is not too tight on the ears when using and I find it comfortable to use along with my reading glasses. Perfect weight.
They are on the light side so not the toughest set I own and so I try not to be too rough with them but so far build quality has not been an issue.
Possibly the most comfortable headphones I own even more so than the more expensive but similar setup B&W P5's I own which clamp my head a bit too much.
Most comfortable and lightweight headphones I have ever worn. Could wear all day which I did for at least 3-4 hours straight without any discomfort.
They fit so loosely on the head that as soon as you tilt your head forward they fall off. It really annoys me. They are very light.

KEF M500 Hi-Fi Headphone - Silver/Black

The headphones themselves are heavy on robustness, but being mostly aluminium are fairly light weight.
The cans are very comfortable and light-weight but in a quality way. I have used them for extensive periods of time for playing.
The headphones are lightweight but sturdy and give the feel that they will last.
The padding is lush and lightweight, and the spring just right for easy but secure wearing.
They are light and they are sound isolating/noise isolating enough for me. They use great materials.

What customers say about "Features"

KEF M400 Over-Ear Hi-Fi Headphones - Champagne White

Great sound as expected from KEF, Folds into a compact case but it is a bit too compact and one needs to be careful not to scratch the ear pieces against each other.
Superb sounding headphones, I'm really pleased with their performance and highly recommend them at this give away price!
These sound super nice and comfortable while listening for long hours. Very happy with the purchase, not sure what others are complaining.
Folding construction damages headphones and controls are temperamental.
The connection between cord and headset is very weak. From the get go, the sound through the left headphone dropped intermittently.

KEF M500 Hi-Fi Headphone - Silver/Black

Very rich sound. Tight accurate bass, extended, even treble, nice open mid-range.
The sound-stage is average for on ear. Don't expect a huge of out head experience. It is very open and airy sounding, however.
The frequency response is fairly neutral with a slight bump in the mid-bass that rolls off towards the treble.
Best headphones I have ever used. Great frequency response, marvelous spatial presentation.
The cord does not get tangled or twisted. I love that aspect of this item. Mostly good clean sound, except in lower frequency that feel shallow.
