Apologies if my description is not very in depth, as I am just beginning to get into audiophile-grade sound.
As a background, I usually listen to Rap/Hip-Hop and quite a lot of Techno, so I am very fond of IEM's with prominent lows and mids, and less prominent highs. I tend to like neutral-to-darker sounding IEM's. I listen to everything out of my LG V20. I own the following IEM's: Sennheiser IE80, Shure SE215, TFZ Series 2, and Sony MH1c.
