I think it depends on how long you have been giving the tones a try for. If you have done each of them once or twice with no effect, I would say that may not be enough of a chance. Maybe try to find one that you really enjoy listening too and stick with it for say, a week or more. Sometimes things like this affect people differently and you really need to give it a good solid go with a little trial and error. Also, I would recommend that you don't make this listening experience a "chore" but more of a fun and enjoyable thing to do instead.

I actually tried the healing Iso-Tone on the site you listed because of some sore throat troubles I've had lately and it actually relaxed me quite a bit. Now I didn't really get much relief from my throat but I expect it may take a few more tries to possibly see results. I personally would try the same tone at least five times before I made my decision if it was for me or not.

I can't really say why you had a good experience with the headache tone and not with the others. Maybe you were more open to resolving the pain that was shooting through your head at the time, then you were to whatever issue the other tones were for.

Look at the positive side, at least one tone did work for you so you can't really say it has been a lost cause. Give a few you enjoy a handful more plays if you haven't already and then make your final decision.

It might also help to have a decent pair of stereo headphones on. I know that helps me quite a bit when I listen to binaural beats or something similar that is used to relax my mind.

Hey Bridget
I think it's a bit like wine when you look at the label or read a label on a bottle of wine.

Dark ruby with crimson glints. Good Tuscan black cherry and a hint of blueberry liqueur on the nose. Dark cherries and black plum flavors and a whiff of fragrant black pepper; very dry and built on a sturdy acidic framework.

Nice poetry but it's how it taste to you that is what counts.
I was wondering how would the Iso-tones work in in a blind test. If you didn't know what they were supposed to do or what the effects were . I think a bit of what makes them work is the placebo effect.
With that said I also downloaded a few of them and have them as MP3 files on my mobile-telephone so I can listen to them just about anytime(as long as I remember to have ear-buds with me ;) )
I like Hazy I find it relaxing. and Third-eye is also a favorite.I usually listen to them in relaxed unstressed atmosphere / meditation.
I do not use them that regularly maybe once or twice a week. But do enjoy them! I have tried others in the past and they did not have the same effect (could also be a download issue,bad stereo modulation). So if the headache recording works keep at it.
peace
