Query: Not worth it!

Do not get me wrong these are good in-earphones and bass is really amazing. However there are several caveats.(1)Around the ear pieces are very flimsy and can easily snap off;(2)You have to achieve a good-fit or seal with the provided plugs to hear the truly remarkable bass reproduction. Once you achieve the seal these earphones are extremely uncomfortable in your ear canal. They are not quite conducive to extended listening. I often listen to radio while in bed and these earphones were remarkably uncomfortable for extended use.(3) I also used them once in the plane and it turned out to be a very bad idea. These snug fits in your ear canal are not quiet good for changes in air pressure.(4) Each time I use these ear phones it is a struggle to get the right fit.I would recommend IE2 Bose headphones any day! Agreed the base reproduction for Bose is not quite as good. But what is the use if can't use these phones.
