My UES are coming tomorrow. Your colleague Vidal doesn't appear to like them much according to his quickie. Their precessedor, the UE are the highest rated earphones on thephonograph.net, even higher than the ZS10. BUT: their criticism is that the mids are not quite audiophile grade. Hope this was improved in the UES. You said they are coming close to the UE900S. Well, we will find out soon. I have also signed up to write a review as I had bargained down the price by $7 (the present market value of a review of mine). I feel they certainly deserve another thorough head fi review including some measurements.
