Bought these headphones twice in a row. Bought only for the built-in microphone, very good. As for the sound itself and other things, I can’t say anything, since they hang around my neck, and there are other headphones in my ears, and you know why? Because they rub their ears terribly. It's just not possible. The wire got tangled in the same place on both models. Now I ordered SteelSeries Siberia v2, so I'm waiting. I advise you to order them too.
