- They completely isolate from the outside: Ideal in public transport, ideal in a noisy work environment (I work in trading room, so open space particularly noisy and I wear them all day to stay focused).
- Which leads me to the point "comfort": In the stationary (ie sitting, at work for example), they are totally forget! It is a remarkable comfort, attention is paid to the quality feel of the materials. I spend my days with no problems. When walking, it feels a little weight but they do not move. However, it does not count playing sports with. And yes, the metal that is beautiful, it's class, it's good for the sound but it is heavy !! And since the headphones, remote control, and the small separation between the right side and the left side are metal ... they tend to slip during major repeated movements.
- The quality of materials / finishes: no complaints, I have for a while now and they have not moved. Used every day, dragged around with me, they are still as good as new! The braid is solid and allows especially cable does not become entangled (we slip in a pocket and the springs, they are already unraveled! It changes the cables of Apple headphones!). For the rest, it is similar, it does not move. For finishes, there is frankly no possible reproaches so this is exceptional.
Finally, go for it! They are much better than competing intras I've tested in sound quality, comfort and finish (Bose, Sennheiser, Beats / Monster Koss Jays ...).
