thanks everyone
i have listtened to w700i w810i ( i have both right now) and w810 snd quality is defnitely better i cant say it technically but i am sure of it
x360 ipod quality it very gud xcept for earphone
both my bro and sis have it but i dont want to carry two gadgets while travelling
like amd64 said i think its better to wait for 4 days as gsma conference is abt to start and nokia and se r going to announce new smart phone and may be prices of current top two will probably drop
thanks everyone i will tell what i bought soon
