i just get xb1 at singapore jaben come with one year official warranty card by sony =)

btw,xb1 really bang bucks! worth the price and this is the sound signature that i am finding all the way~ =D
i tried xba 1,xba2 n xba3. xba2 just stay at my ear 5 sec only, it sound very weird to me. xba3 more better in overall, got 3 driver which each driver do their work nicely but my personal preference is vocal, xba1 vocal more warm, more magnetic ~!

i do compare with er6i, er6i vocal become dull, and dry; xb1 sound more musical,warm and magnetic (in another term is the mid very nice)~

bass is there but not strong.as i use to etymotic er4p and er6i bass respond, xba1 bass is just nice, the quantity of bass is better than etymotic series =)

as i say,rm199 really worth for the sound signature =) even in i play directly frm my samsung tab 7.7, the sound still very impress me =D for sure, with a proper amp,it will become more better, some how with amp,the bass will be more good~

ohya,i do compare to klipch x10 and triplefi10, i still prefer xba1 xD

*the review is based on my own preference song which is more toward vocal, like emi fujitra, 蔡琴， corrine may, olivia ong

do bear in mind that double amping most probably will make the sound worst, i use line out frm itouch with a proper LOD + zeroD amp do make xba1 fly =D
