The sound quality is excellent, but there are two problems with this product:
1) The cord isn't long enough. I use it with my iMac and it's barely enough to reach me. Yes, there is an accordion spiral, but that doesn't help much because the more tension you place on it, the more it wants to spring back into place. If I want to lengthen it, I find I have to put a paperweight on the cord to keep it from springing back into its original shape.
2) This headphones get HOT. My ears get so warm that wearing these headphones becomes uncomfortable. And what's the point of excellent sound if you don't want to wear these...
If I could get my money back, I'd probably invest in a different pair.
