Comment: Treble tuning is one of the best up to $200 range. Neutral bright decently tuned, decent soundstage, surprising treble tuning Limp bass with zero texture, might be too bright for some

Sounds like vocalists are asphyxiating. Very thin note-weight. Precogvision Youtube Channel
Budget tech king due to neutral bright tuning. Needs and loves power. My favourite sub-50 set so far. Might come out as shouty/hot. Responds well to EQ and Moding. Beaten by CRA(bassy) and Titan S for my library.

Nice tone, great overall sound with only a few issues. Jaytiss Youtube Channel
A warmer/less sharp EW200, a slightly more resolving BLON Z300, price might be an issue tho Jays Audio Youtube Channel
