Yeah. I'm in the same boat. I used the XBA-3 at work today and connected from my DACport feeding all Flac was a great experience. If only the cable was a normal Y and not a J type. I'm usually ok with J type cable but on the Sony the left cable is way too short and the intersection block alway grab my collar. Just very annoying. But they sound good .
Are you using a clip? I had to grab a clip off of my other iem's and use it on the xba3's to save me from being driven bonkers. Now I actually like the setup... I often need to take the drivers out of my ears (you know, like when forced to interact with people), and I find it nice how they hang on the chest out of the way, yet are ready for action :)
