I dunno what's going on exactly but we're getting into a lot of vaguery here, I think. The "energy of the music" or detailed but not resolving...I find that, conventionally, V-shaped IEMs sound more vibrant especially to people who don't chase very neutral IEMs, don't think a mid-scoop even traditionally makes the IEM lose "energy", but I could be wrong!
In my case, the Tape felt somewhat hollow until I found the right tips. I really dislike that the shape and placement inside the ear play such a huge role because I cannot be sure at all what everyone else is hearing. At first it had potential but the large treble hill just made all the instruments mush together on louder parts. Now I am really satisfied with it, but rather than saying oh it's just the fit just experiment with it, I think it's a big drawback to an IEM when it's this finnicky. It could also be me but I've never had this problem with any past pair (granted I'm not a collector/"hobbyist" so I haven't owned really that many). Compared to my current over-ear pair, the K240 MKII, which is very much operating in the midrange, I don't hear a lack of energy either, just the presentation is very different, especially with the vocals
Not sure, but for instance... this sounds amazing with the Tape
while a song like Sister Sledge sounds hollow and thin.
