Can i use this headphones with xperia sp??
Sony headphones work best with Sony smartphones.
If you want mobile,those seem to be good.
I am using the SONY MDR-XB400
I am an audiophile,had the MDR-ZX100,ZX300,ZX310,and these headphones top it off,and i payed 60$ for them.The sound is clear,sound isolation is perfect(you only hear the music,and others arround you cant hear what you listen to),they are extremely plesant to have on the head,those coushins feel like clouds(so soft!),and the bass blows you away.The headphones are so good,they were worth every penny.
