So I've been content with my JH16s for over 2 years now and have been avoiding head-fi as much as possible during that time for the sake of my wallet. Though the JH16s are still performing like a champ, my ears are so accustomed to the sound and I don't enjoy it as much as I did. Hence I'm in the market for a new pair of IEMs. After my 2 years hiatus, there are now so many new companies and quite frankly, I'm so lost I don't know where to start.
I discovered Heir Audio recently and read through many of their threads, it seems like they have a great track record so far. News of their anniversary sales is simply icing on the cake and I'm eyeing the 5.0. But I want to do my homework properly so may I hear your opinions about other alternatives in the price range ~$500-600, and their advantages over the 5.0 (if any).
