I use it for 2 months. I have the AKG K55. Basically it's the same with bass présenetent. Regarding sound, I'd say the price / quality ratio is good. It needs to be adjusted over time when the head too often looks like a lot of headphones. But it is lightweight and can plug into a jack 6.35 or 3.5 and it is rather beautiful, it makes it even better.

For purists and lovers of details, see the headphones or X 5 times more expensive. So for the price, I would do this choice.
