What I liked immediately after the purchase, it is the comfort of these headphones that are placed right and left ear - each with specific ergonomics - without hurting, which is quite rare for intra -auriculaires! They arise in your ear, do not move and protect you bonus ambient noise without isolating you completely. Tested in Paris, in a bus, on 26 December, I know whereof I speak.
The sound is excellent for this price range, with deep bass, but also good quality midrange and treble.
Design is more than I ever neglected: an elegant box that can therefore make a real gift, rubber cover two pairs of two different sizes, in addition to that which is attached to the earphones, a main thread large quality with a heart made of Kevlar, a remote control to mute the sound if needed, the ability to clip them earphones to wear them around the neck and a final practical idea: the wire can be blocked by a "loop" that avoids having to unravel when the ears are in your pocket.
I also tested the quality of the built-in microphone on the wire of the left atrium, on the remote which I speak above, and the sound on the phone, reception and transmission, is excellent without having to shout.
I am delighted with my purchase and I recommend very strongly these Kransen.
