Sorry to keep bothering you joker but I just found out that my brother (the guy im buying these IEMs for) doesn't really care for an extra emphasize of bass, so that basically screwed up my selection of headphones lol. The important aspects to him would probably be isolation and comfort since he will be using them on transits everyday. He listens to mostly alternative stuff like Lana Del Ray and Ed Sheeran with a mix of hip hop like J. Cole, Kendrick Lamar, Frank Ocean so what would be a best all-rounder I guess. The GR07 looks good at this point but don't know anymore haha. Thanks again for the help!
