Pros: Nice sound, comfortable
Cons: Nothing comes to mind.
I opened the box when these arrived and spent the next four hours listening to these. I was quite impressed right out of the box. My normal phones are Shure SE 530 and 535 IEMs. I bought these mainly due to the buzz that these are great cans for a low price. I am very pleased with them! I have been running them in for the last couple of days. I hooked them up to a Squeezebox and let them play. I have read that them warm up nicely after 40 hours or so. I liked them just fine out of the box, if they improve I'll call that a bonus!
