I find them quite comfortable headphones and take very well. They are not necessarily very discreet but it is not very important. I understand that they can interfere in time, the tip is badly drawn and effect "boost" low fit into the hole way too pronounced which can make it difficult after one hour. However well it takes me an hour before I find it really annoying, before it goes nickel and all the more I realized there not too long ago that we could adjust the atria vertically, has greatly improved the comfort of the helmet!
In short: a good helmet for sports on sessions under an hour.
