Ok enough of this , I am neither a nokia fan nor of that of sony . I have used many products from both these brands like n91 , k750 , psp , w810 , father uses w960 , neighbour has k850 etc I am here to tell only the truth . There is no phone brand present as of now that can touch the quality of an ipod . K850 and n81 are far behind . The only phones that comes close is n91 and w950 (not w960 ) .If someone disagrees to this then i am sorry that you have not heard from the ipod. Even the iphone's sound quality is not good as the ipod . I agree that cowan has some brand that can beat ipod but they are not a phone . Regarding k850 and n81 any normal person who listens to both with the same headphone will agree that n81 is slightly good in music but overall k850 is a better phone since it is a cybershot . Honestly speaking there is no difference in sound quality in k850 or w960 ,w910 and many other SE brand , the only difference is the volume output .A dedicated 3.5mm jack makes a huge difference . There is no 3.5mm adapter that can use the full potential of the phones sound output , for this try listening to the music from the same phone with a bluetooth stereo headphones then u will see what i mean to say .Reviews from gsmarena or mobile-review.com are only subjective and actual checking is required to to test the capabilities of the phones .
Now , sony and nokia fans can continue to pull their hair and post vulgar comments about each other , smart people know the truth , they will just read and laugh at what these fanboys have to say .
