These headphones are designed goods, comfortable to wear and, most balanced output sound with excellent bass. The noise of the cables are well filtered. I think the price / quality ratio is exceptional. I did some comparative listening with friends who have much more expensive models, and were surprised by the result, which compares favorably. In short I am delighted with this purchase and can only recommend this product! PS flaw though: identifying GD is not great because little visible, especially if it is dark.
