I purchased these on Amazon and used them for about six months for FPS games (several hours a day). The heat has dissipated, and I don't really need high-performance earphones anymore, so I'm selling them. These earphones made it very easy to discern the difference in footsteps and judge the distance to enemies. The outer box has some wrinkles and dents, but the product itself is in good condition. I only used the white ear tips, but I switched to separately purchased tips after about a month.
