if you really dont know what the model number j22i j22a etc mean... m doin this review for you..
the j22 j33 or j55 etc are just earphones with no remote for mic or other control buttons.
if you want a controller and mic.. you have j22i or j55i etc to be used in a apple product.
for android and other users you have j22a j55a etc..
a for android
i for apple
nothing for nothing
