This is an experimental blend/mix of isochronic tones, it does requires headphones or a headset, otherwise it sounds weird. I mainly made this video for myself, but it seems that many others like this combination of frequencies as well. I like to listen to it, sounds good and feels good in my brain/body. However it isn't a pure isochronic tone, I have no idea what effect it has ( if it have any), I'm not a"healer". So if you experience any discomfort listening to this video, please stop.
