They cost like Phonak 232s. You know it wont be long before we get a compare. I suspect the Sony's will be cheaper, looking for more distribution while making their own drivers for easy assembly. Along with the Finals, W4, 535se and the MA's, there looks to be a new wave of contenders.
Sony's are cheaper, too bad that there are not too many specs, the 4 driver XBA-4 model only cost 500 SGD(via Sony Singapore). Really wondering how does this compare with the other top-tier offerings now since it is pretty expensive for a 3 driver BA. That being said how much did your MDR-CD900STs cost? I would like to pick those up sometime.
