An effective and pleasant stereo headphones

The +
* Sennheiser sound quality that I like, the headset may not be as neutral as some want, but it's enough "fun" for the majority of the population
* Comfortable, completely covers the ears even with glasses. Can be worn for several hours without a problem. I also added that unlike some headsets leather helmets, they do not heat foam (so you do not sweat and does not tire the ears).
* With my settings, I can get a powerful sound evenly and ensure that at no time did I saturation. The sound is nice and quality in all circumstances.

Les -
* The design may seem mean, you can not say he does cheap or luxurious, we end up with a hybrid product category, which is a shame for a stereo headset
* Insulation is quite low (even for an open helmet), and when pushed a little too hard on his neighbors benefit fairly quickly. I specifically was looking for an open helmet so I knew what to expect, but I do not think it would be as isolated from my other open helmets

I'll just emphasize its qualities which are of sound quality, comfort, accuracy of sound (except the bass perhaps) and being an open helmet (I do not like closed helmets). It would be a shame to take all these qualities for granted on the pretext that there is better elsewhere (there will surely always better elsewhere). Having recently been disappointed by some helmets dating from 2012 and 2013, I learned my lesson and will restrict myself on quality helmets recognized like this.

For me the HD 518 headphones became my only dedicated to music listening and watching videos. I clearly asked nothing more of a helmet that everything he already has, so I am 100% satisfied and I recommend it very highly!
