It is really good bang for you buck with this bundled package. 16 different binaural beat tracks and headphones. I have purchased others before and it seems like you have to get a new $20 cd for every single different thing and here it just includes everything!!! i really like using it for meditation, as i have used a lot of different types of meditation music before this does not get stagnant as you can switch between different CDs depending on how you are feeling. I do notice i tend to use the Alpha CD a lot more then the others, it just tends to resonate with me better.
Itsu sync has become part of my daily routine, alpha in the morning, beta or gamma mid day and delta/theta before bed. ahhhh the happiness, relaxation and peace it brings me.
Worth every penny. you cannot put a price on your brain and this keeps it sharp so it is a must for everyone. I highly recommend it.
If you want to meditate just use the ITSU CDs They really work. I am getting a second set just so I am never without them. I can say enough about how fantastic these products are and how they have helped me.
