I use these headphones for 3 months and it regularly. Its sound quality is good, the highs are very detailed and the bass present but did not crush it. He seems quite sturdy, its Achilles heel in my opinion is the small cable that connects any end to the amp or whatever. Fortunately, it's replaceable. I use it as headset for voice recording, it leaves little efcape her. It also reduces outside sounds good. Price or it can be found (55 € in Paris) is a very good investment. In short, it's good.
