Former owner of a pxc 310 bt (headphones active noise re-education) who accompanied me a little over a year and a half, I'm very happy with the purchase of this Sennheiser HD25-1 II. If they disregard the style of the adidas version, which may please or not, these headphones produce a very good sound, clear and limpid. I find it very balanced in its audio response, whether on electro (it's a DJ headset to the base) or the French variety, and even classical. In terms of isolation, these headphones are really good. Although active noise reduction headset isolated from my old best, passive isolation of the HD25 is really on top of breath and also prevents an active insulation, which can be heard when the latter running. I'm just a little disappointed with the quality of the plastic, which I think for 180 euros, could have done a little less fake. But I quibble might be a bit because I abusing my lot headphones that accompany me everywhere. If you prefer a more austere style, this headset exists in many versions.
I recommend this helmet for people like me, listen to music very often nomadic way and also at home, to appreciate the richness of their song library.
