You can tell the difference in quality when compared to sunglasses hut they are have the price. I ordered a WHITE with GRAY marble & thought it would be a glossy look but it’s NOT. Me sucedió que, a medio entrenamiento, una de las patas delanteras se abrió y se soltó la bici. I havent noticed any issues with the functionality of the cord, but I am sure the durability and lifespan of this product is compromised and it certainly was not in pristine condition. And comfortable to wear. You dread hitting the cold floor- but wait! I am using it for purses and backpack and it is holding all that weight so far! I returned the two that I originally ordered. To finish off this review, Im going to mention the pros and cons of this headset. Hands-down, my most fav headphones Ive ever owned!
