Bests & Worsts Reviews from Amazon

Bought these for my fiancé for work , the sound was good but they have already stopped working on the right side after less then two months( even with only a few hours of use each night and gentle use) . We also were supposed to get a free pair from a card the seller sent with the order but that never happened either.. Won't be buying from them again at this point... Update : so a month later and I get an email from this seller : "I am sorry that there is a problem with the quality of our products. If you are willing to delete your review, we are willing to refund you $ 30 as an apology. We are collecting feedback and improving the product." Steer clear of this seller ,they don't stand behind their products and don't even offer a refund for the purchase price ..
