I just got these and am quite impressed with them. Not much burn in - just about 8 hours. From the get go, they sound better than the Atrio M5 and the IE8. They may be quite close to the Monster Pro Copper even, very clean and natural sound with very good extension on both ends, without messing up the midrange. They sound really quite satisfactory and have excellent comfort. I may end up preferring them over the Monster line after all but yet to give them more burn in time and test them with more music styles, amp and unamped, different tips, etc.
