I'm kinda new to here, so if possible, please don't use technical terms .... Thanks in advance 
I've been trying to buy a new headphone for my new phone (which I haven't bought yet, but probably it will be the Xperia Z), and I was stuck between the in-ear earphone XBA-40 or the over-ear, wireless headphone MDR-1RBT.
And yes, I'm a Sony fanboy.
Originally I want to buy xba-4 as many sites say that xba-4 sounds good, but then Sony released the newer xba-40. From what I read in this forum, xba-40 sounds better than the xba-4.
What got my eyes with the MDR-1RBT is its design and the wireless function, and studio quality sound. At first I also considered the noise-canceling version MDR-1RNC. Although most says the sound and the noise canceling function is good, some also says that it hisses in quite environment.
I usually listen to pop and rock music, instrumentals (mostly game or movie soundtracks), and some classical musics.
Could you tell me which one I should buy? Or any other recommendations (price range 300~500 USD)?
Thx a lot 
p.s.
I'm studying in China now, so I'm buying my headphone there. The thing is, the pricing is different than in USA. If the item is sold by official seller + made in China, it's usually cheaper than in USA (MDR-1RNC for 2300 yuan in Sony Store - about 380 USD), but if it's not meant to be sold in China, like it has to be imported in small quantity, it's ridiculously expensive (MDR-X10 for around 3000 yuan - or almost 500 USD).
















), I just like how smooth things sound and it plays pretty loud! With iPad2, although it didn't play as loud as iPhone Original but it sound really really good! With iBasso D7, it give in too much bass for my taste. Overall, I find it sound best with pop, rocks, classical, acounstic because of it's ted metallic sound. If probably drived, I much prefer this over MDR-1R.
Because I like to hear the details of my musics, but I also like to hear the 'thump' on my ear. Plus, I really love the design of MDR-1R series
