“What your headphones say about you?”
My 2 favorite IEM's are the Rockit Sound R-50 and the TF10. I think what they say about me is that I like great SQ for a great price. I have others that cost more but they don't sound any better than those 2. They say I like a balanced sound with good clarity along with a good soundstage and I think that's what the 4.Ai is about as well.
