Got 7k baht Sony's on now, hardly any better than wax ear plugs for cutting out noise. I was replying to a previous post, you must have missed this:
.' Here is a better idea: Buy a pair of Noise Cancelling Headphones. Either Bose QC II/III or Sony XM4/5 will do the trick. I have both. The Bose are in my village bungalow, the Sony's are here at my house in the city. Both work well, but the Bose are better. Mind you they are expensive, but they absolutely get rid of loud noise without the hassle of trying to find good neighbors. They're also portable so use them in shopping malls, extremely loud concerts, festivals, weddings, funerals,' etc.
