I am really looking into getting a pair of custom IEM's and seeing how I like them. I have come across countless reviews and impressions and have found myself at wanting the Heir Audio 4A's. I enjoy all kinds of music and am really looking for accuracy, clarity, and clean/tight bass. I have also come across 1964 Ears quad driver and the JH5's, are there any other recommendations in the $500ish region? I am getting my ear impressions this week, is there anything specific that I should tell the audiologist before the impressions? Thank you guys very much, I appreciate it!
