I had the CKM55 and I can tell you right now those don't come anywhere close to the complete sound of the CKM500. I don't know if it was because it was your first iem but believe it or not the CKM55 was the single worst iem out of all the previous CKM earphones. Even the older CKM50 was better than those..You are in for a nice surprise..Considering these are an improvement over the CKM77 and the CKM99.
You can only imagine just how much of an upgrade in overall sound quality you are getting over what you had before. Believe me there is no comparison between the older CKM55 vs these CKM500. As for your music what you will hear is clarity and detail with your depth of music.The lack of any detailed highs on the CKM55 was a killer for me. Lower mids were muffled on those with the bloaty bass those were the only CKM iem I returned. I couldn't believe how lacking those were. Nice choice on the upgrade you will hear proper now. I look forward to your take on these. All 4 of them vids sound nice. I especially enjoyed Hendrix the best out of the 4..Been a while for me to hear some Eddie Money.
