o the headphones are fully plastic and have beginning at head movements / chewing movements (chips etc.) creaked, but oil could be eliminated by a small splash of silicone - since noiselessly
+ Good processing- ever fallen down, but no damage
+ Good wearing comfort - especially the semi-open system, that the ears can not cook :-)
++ Great sound for movies / TV - especially with the loudness function (now do not know how it's called). Deep bass' clear highs and midtones. For music before anything comes through the Cowon J3 or similar Cowon product ;-)
+ Music is a problem - as I had read when buying in a recession, the volume is throttled when a certain number of decibels, which is very striking. A great pity, because the sound of the handset really crystal clear with great bass (I repeat myself, but it's really true) 'So a super dynamics (even at low volume) penetrates your ear.
+ After habituation, easy access to the side of the right earpiece attached controller, I though the regulator no longer anpacke (about 70 '% volume on the handset and the base volume via the amplifier rules).
+ No noise by radio etc. - In silence Kannes sometimes slightly noise, but this can be turned off by the earpiece volume is set high - Strengthen rest (see above)
Previously had the RS 170 that shone only with tinny sound '- there are worlds 170-180.
Can only recommend, if you use it primarily for TV / Movies headphones. Otherwise, the corded points.
