Basically the xba-3's are $150 and the xba-4's are $200 at harvey norman right now... Thats cheaper than ebay! Its worth getting them for that price, i got the xba-4's and I'm very satisfied with them. Although does anyone even want the xba's anyway? They seem very unpopular in australia, my...

well, i want a high end IEM, but im not sure about all the pro's and cons of armature IEM's and single dynamic driver IEM's. And i want to know if the XBA3/4's are any good, especially with bass and clarity of mids/highs.   And anything else with bass and cool stuff.
