I would pretty much agree with the below
Let me throw in one other thing (because I know some are wondering who have the AT earphones). Is the IM70 better sounding than the CKN70? Yes! I'm doing a sneak comparison now. The dual dynamics are beating the micro-CNT .... Simply, the IM70 has a fuller, taller, and more detailed sound than the outstanding CKN70. All of these AT earphones are wonderful, and as Dsnuts, waynes world, sf, and DannyBai can all attest, I've never been a AT fanboy. I loved the JVC house sound more than the AT house sound. But that changed with the CKS1000, and then the CKN50, CKN70, and now the IM70. Happy listening.
