The music quality option is not working on my Iphone 5

Why isn't there any difference when I switch the music quality from normal to exreme, it sounds much more worse than I listen it from my Mac.

It is possible your app is playing data it has cached previously which it does to save bandwidth and data usage on mobile devices. If you do a quick clean reinstallation (although you will need to resync any offline content) and then make sure the quality is set to Extreme before streaming your tracks you will definitely hear them at full quality.

I already tried that before but it doesnt seem to be working, I even deleted the app and reinstalled it but it sill not work. I also tried to stream in the "extreme" quality but it is also not working.

Are you listening via headphones or external speakers?

I am using a headphone shich is from Bose and I was also using the same headphone when I was listening with my Mac.

And the differences between listening the same song with my mac and my iphone is quite big too.
