Well, just thought I'd share this little tip with all you owners of the XBA-4s who might be a bit nonplussed by the veiled nature of the mids on these.
After becoming very frustrated by the muddiness of mine, when playing through my Samsung Galaxy S3 (international version, which has the 24bit Wolfson dac chip), I sat down today and thought I'd have a look at the filters in these things.
It seems what Sony had done - in my pair at least - was ram a lengthy wodge of very thin foam in the nozzle. Not just a thin gauze filter like most iems I've owned (and I've owned a fair few in my time), but a sizeable lump of this stuff. Presumably with the idea of damping down the highs.
So, being intrepid, I took that sh*t out and tried the 'phones without any material in them at all.
Et voila - huge layer of mud was removed from the mids, and all the clarity and depth I could wish for and a veritable tsunami of beautiful noise was suddenly hitting my ears and giving me a stupid-faced grin.
I'm utterly blown away by how good these things are and how much of a transformation there's been in the sound. Instead of contemplating taking them back to the shop, I now want to sleep with them and have their babies.
What were Sony thinking??????
Or maybe its just the pair I got? Anyone else willing to try and report back?
