I'm not sure weather they sound really good with my SP as I don't know the output impedance of my SP.
can u help me how to find the output impedance of my Xperia SP. (Stuck at this point).
It'll work alright with your phone, the volume might be marginally lower than other phones. I've used my XBA-3 with a bunch of phones and I wouldn't say it performed badly on any. It worked fine on all smartphones. On the Nokia X1, however, there was a very faint hissing noise in the background. The XBA-3 will work fine on your smartphone, but it'll definitely, hugely benefit from an amp or dac+amp to bring out its sound.
I'd also like you to know that I've had the XBA 3 for almost a year now. I did enjoy it for a few months initially, but for the last few months, its been lying in my drawer. I've been using the Soundmagic E30 as my primary IEM.
The XBA 3 is still 'technically' a better IEM. It is more refined. But after a while, I realized that theres a few things that the E30 does better, and those are the things that I value more in an IEM. The E30 is airier, has a nice tight bass and is more spacious.
Basically, what I'm trying to say is, the XBA3 isn't a bad pair of earphones, and is definitely worth the ~$100 price point (maybe not the ~$200 price point that I paid for it a year ago). But while it is a great IEM, its not a very enjoyable one. Its hard to understand this difference before you've really spent time listening to different types of sound signatures, and I doubt you'll know what I'm trying to say.
The E10 is a very enjoyable iem and the XBA3 is a very technically impressive iem. Both are worth your money. But I think that E10 is safer as it has a more 'likable' and immediately understandable sound signature.
Remember XBA3 was sony's first attempt at using balanced armatures. They have shortcomings. These were apparently fixed in the XBA-30, but I can't find it for sale in india.
If you really want to spend money on your first purchase, I'll also tell you to consider the Logitech UE600. This is available from proaudiohome at around 5000 rupees. This one's a BA too.
