The sound is perfect: clean, detailed, clear, clean, good image sonore..Pour this price, I think we can do better, a notch or two above (100-200 or what) would produce a sound of a clarity and infinite precision.
But also a lively sound: the sound is not neutral and empty, on the contrary we feel good music whether for voice, treble, bass, bass ..
whether calm or dynamic music (except electro I have not tried).
However the sound is not distorted is faithful remnant. For that price, it's worth it. After it will be necessary to have at least 100-200 a precision sound "infinite".
Too bad I can not find the same very high standard.
After there was just low enough that are raised relative to the rest, one likes or dislikes.
Hardware side there is a jack, a pocket with 4 additional bundle (3 different sizes of tip), an extension cable and the main cable has a "knot" for removable formed a V above cable to the headphones (I not sure if I am clear.)
Be careful though to choose its size tip: the one set by default is too big for many people (which explains the com negative part)
