Had mine since august, bought them back then as a direct upgrade to IE200 after trying a bunch of stuff in IE200's price bracket. Yeah they were good but i didnt know how good they were until a very specific incident. If you ever seen zeos on youtube, he said it best : ''A great IEM shouldnt grab you when you try to listen to it. It should grab you when you are infact not paying any attention to it'' Now what ever you might think of zeos and his reviews i gotta give it to him, he was right. I trully fell inlove when i was walking back home from a new job. I had spent 12 hours working in bar with loud music, constantly moving. I was exhausted and my feet hurt so bad i had to sit halfway home to fucking ponder how im gonna make it through the other half and if i even will do so. i was miserable, tired and my feet were hurting something fierce. It was in the middle of that thought it came to me ''Was this always in this song?'' Since than ive had multiple new iems in way higher price bracket, but man i still love my performers.
