Headphoneus Supremus
Maybe, I am treble sensitive and don't like harsh highs, but I don't find ZSTs to be comfortable when I wear them for extended periods of time. I ordered ZS3 from gearbest as it is just $10. I know that they are not going to be as detailed and clear as the ZSTm but I hope I will like them. They are getting good praise on these threads.
People are also saying I have the same problem as you, I think we will like our ZS3s better.
