I've been using these headphones for several months now, and here is my evaluation: they sound great, but they are one of the most uncomfortable in-ears that I have ever used. It's difficult to put them on due to their size or design, and you really feel them after a while. The cord is very thin and seems fragile, but that is just the appearance, I hope. The good part is that they have good attenuation of exterior noise, and they are very detailed. I would buy them again because of the price, for sure. They are worth it.
