I have a similar type of headphones by
Tooks...some materials creep me out and these work pretty well...Noticed them when I bought my daughter a winter hat with the headphones built in.
When My insomnia is only a little bad listening to showtunes/soundscapes on my local cable channel just a tiny bit below a normal volume helps (mostly no words). When it gets a little worse, a golf program on the TV helps ALOT.
