I do not recommend those drivers, the sound quality is very POOR, you will only get high frequency and some medium that's all, when you apply low frequency those drivers can't handle. I'm very unhappy. Money throwed away.
Very pleasantly surprised by these drivers. They give a new and better life to my hopeless Sony MDR-ZX600 headphones. These are closed cup headphones, so it's still a little dominant in the midrange, but now they're quite enjoyable. Plenty of bass, plenty of high. The sound is crisp and detailed. I may order again for a semi closed cup headphone. Thanks.
