Then there are many other interesting IEMs below $150 -
Brainwavz M3 (quite balanced but without neglecting the "fun" part),
Fidue A73 (dark-ish v-shape, I love it personally as a "fun" IEM that is not too exaggerated) and
A65 (smooth and dark-ish, somewhat warm signature),
Pai Audio MR3 (relatively neutral, really good soundstage & imaging) and
MR2 (bassy with a peak in the upper treble, good soundstage & imaging),
DUNU's Titan series (all somewhat v-shaped, but the amount of bass you get highly depends on your ear anatomy and by the amount of by how much the inner facing vents are blocked) (whose treble is on the undeniably brighter side though), the
Apple IEMs (not too far away from AKG K701's signature with regular insertion depth, becomes more full-bodied and darker with deep insertion),
Phonak Audéo (fairly balanced with the grey filters) and
UE600 (fairly balanced) (if you can somehow get one of those two somewhere),
Fostex TE-02 (balanced IEM and one of the very few models where I would say sound quality is clearly above the price - even beats some of the single-BA IEMs below $150 I love on the technical side),
Havi B3 Pro I (warm-ish balanced sound, large soundstage, excellent for its price, but there is something that I don't 100% like about it - doesn't sound 100% coherent to me although it is technically a top IEM for its price),
MEE audio A151 2nd generation (dark-ish and warm, quite good soundstage).
Just to name the models that I like and would recommend.
I think the model with the least risk would be the Fidue A73.
