Hello Lilasrose,
First, welcome to the forum and I hope you amaze yourself with the benefits you get from BrainEv.
No, I would not read, do homework or anything else while you do your BrainEv session.
BrainEv is a subtle and extremely effective entrainment program.... therefore you will want your brain to be free of extraneous activity so that your entire brain is free to deal with entraining - believe me, this is already a big mental workout.
By the way, you don't have to attentively 'listen' to the track, you just relax as deeply as you can, put on your headphones, and let go........ the magic of entrainment happens when you deeply let go.
Best of luck, Pure Bliss
