I could check these effects is not, however, after a few times listening detected that a strong physical rest effect is noticeable. The spherical sounds are underlaid with overtones. Each piece of music is a different frequency in the brain produce (4, 7, 7, 4, 5, ...). A headset is not necessary.
This CD is ideal to come down after a stressful day. I would have expected that I would wegdrösel and warm and heavy (like actually mostly when I go into theta). But that was not the case. After listening to I feel balanced and relaxed. I highly recommend this CD can recommend to buy!
