I have never written a proper review before, so please don't judge me too hard. Tested the unit with iBasso DX160.
I was pleasantly surprised with this IEM. Very musical and non fatiguing sound despite it being full BA set (BA timbre and treble eating the "natural sound" away a bit but not bad). Also the bass is nice for BA. Very clean and just the right amount, only the slam is missing but that's understandable. Nice sub-bass, but there's a small dip around 55hz compared to 30hz which is noticeable.
Mids and treble are great to my ears. Pretty bright, but somehow non fatiguing. I have pretty young ears and I can hear over 17khz but still no problem listening them for many hours (in comparison DT1990 I can do 30 minutes max, Lokahi seems to have just as much airiness but the treble wont overwhelm the mids/bass.). Great separation and a ton of detail. Soundstage is average, though is feels that I'm hearing further behind than front. Fits all kind of music, even trebly metal music. Sometimes male voices sound a tiny bit more distant than others.
Build quality and fit is okay, you can tell it's hand built. Also I don't know if the vent does anything, with silicone tips I get very bad vacuum effect. Overall very nice set, goes straight to my top 3.
Thanks Linsoul for offering this and thanks BGGAR for informing me about this great set!
