So after browsing Kaymu for a couple hours and being mind blown by such cheap offers and their whole "free shipping, pay on delivery, 7 day return, etc" system, I feel like it's too good to be true. I was particularly searching for headphones under 2k and found so many steel series offers such as the 3h, 5xb, and the 7h but the prices are dirt cheap..... How can this be? Are these fake or legit?
