Summary: For people who want to suppress unwanted noise (like the drone of jet engines) but have little space (like the seats in coach-class jets), this little sucker is for you. It cuts out almost all outside noise, can plug into i-pods or airplane movie jacks and give you crystal clear sound.
Summary: Excellent quality sound for a reasonable amount of money. The build quality comes in for some criticism, you can't have everything and good sound as well, well you can if you want to pay 3 or 4 times as much.
Pros: Very good quality in ear head phone - excellent noise cancellation - it is possible to simply relax and enjoy a very musical experience
Cons: slight hiss on occasions but not really audible when listening to music. I think these headphones are slightly unforgiving with old or not so great recordings. I personally don't find this a problem
Excerpt: I use this headset for about 3 weeks, daily. Despite the lightweight GNR blows at the start of Systm active, the overall efficiency for rduction background noise is terrible. When APRS good hour away, the j'teins Systm active, I am always surprised at the magnitude of the ambient background noise!
Excerpt: J'utilise ce casque depuis environ 3 semaines, quotidiennement. Malgré le léger souffle généré lors de la mise en route du système actif, l'efficacité globale pour la réduction du bruit de fond est redoutable.
