I would guarantee you that those TRN V80's sound every bit as good as your SE215's if not better. In fact I think they sound better than any other IEM you can get for under $150. BTW the TRN V80's have quad drivers compared to your SE215's which have only one. ChiFi is the real deal. Maybe it is not to late for you to return these SE215's

I only use them when I am outside the house and they tend to take a beating. When I am at home I listen to my Sennheisers and never touch IEM's.
One last note Betty. What type of audio files do you even listen too because if you are still listening to MP3/4's then you no right to be commenting on what is/isn't proper HiFi.
