I don't think you should have given them away tbh as I know you don't have a high budget set and these are probably the best iem's you can get in this price range. Hopefully the CKS77x will be the one for you but if not, you will have to spend more if you want an iem that is as good as these CKN70's.
+1. I'm sure the CKS77X will be awesome. AT just keeps getting better and better with every release. Hyped for the newest solid bass tech.
Don't blast em too high, lol. If they're too loud to listen to, that is good enough.
