I bought these headphones based on a recommendation of a friend, who was very confident of them and more bought on stock. As the price could hardly be lower, I have decided to also equal to buy two pairs and was not disappointed. I already had a lot of headphones. From sports headphones up to 50 euros, about 5 euros headphones to headphones as free giveaway. Especially cheap headphones have a very unique, "wrong" sound that I've tried on my MP3 player via equalizer for improvement. These headphones should be good, however, unusually loud friend, so they were infected out of the box and in fact: Such a sound I've never get for 10 euros. The sound quality was subjectively no worse than my already gone to break 50 Euro headphones, if not better. After about six months, they are still running as the first day, so I can only recommend. For this price, there is probably no better headphones on the market!
