The MH1s are more laid back sounding with great musical detail in the upper to mid registers. The bass end is not as tight as the CKM500s I think timbre detail is better and more defined on the CKM500 as a result for me at least, overall enjoyment I still prefer my CKM500 over them but MH1s are very nice sounding iems in their own right. And is probably the kings of value for the cash right now. I don't plan on selling off my CKM500 for the MH1 let me put it that way. I know there are some guys that claim the MH1 is the best sounding iem for them having them sell off all their other more higher end iems but to me they are similar in value and ranking sound wise to the CKM500. FXD70...These 3 iems MSRP wise is very similar too. Just that the MH1s are now being sold in bulk for much cheaper which gives them the edge in value. The cord for the MH1 is truly not good.
