An important note regarding iTunes settings
We've already pre-encoded all of our BrainEv audio sessions into the perfect, high-quality MP3 format for you.
If you're putting the file into iTunes, for copying to your iPhone/iPad/iPod, make sure that the 'Convert higher bit rate songs' option on your device 'Summary' tab is NOT ticked.
iTunes tries to save space on your iPhone, iPad or iPod, by reducing the audio 'bandwidth' of songs. Most of the time, the difference is so subtle, it's not even noticeable. So it makes sense to compress regular songs in this way, and save space as a result.
