These intras are comfortable enough: they place themselves well in the ear and the different sizes of silicone corks to find those that are most suitable. To my taste, sound rendering lacks some dynamism in the treble, but the whole is fairly balanced, we arrive at a satisfactory adjustment of sound with the equalizer smartphone. These headphones are very well recognized by the Compact Z3 and therefore the noise reduction function is activated. This reduction is very effective and particularly remarkable in noisy environments like an airplane: you hardly hear the sound of engines! The only complaints we could do to SONY are not having integrated a microphone and a pouch for transport and prevent the cable tangling in the pocket.
