The MP8320 will surprise you..Much better mids and highs on them with solid sound staging for earphones. The only problem with them is how big they are and better tips is a must.
By the way I just saw this on the for sale forums. Ulogin is selling his SHE9700 for $20. Anyone that want an actual improved version of the SHE3580.. The She9700 is an older iem but I am sure uses the same driver that is in the SHE3580 but with a bigger longer housing..The results is better instrument separation, a bit more highs and mids as well as the bass. It is more of the SHE3580 sound.. http://www.head-fi.org/t/607800/everything-must-go-er4s-and-x10-added-worldwide-shipping
